Its distribution ranged from southern Bolivia and the Pampas in the north southwards to the southernmost part of Patagonia at around 52 - 53 degrees south, the furthest south of any Pleistocene ground sloth, with some of
357-433: A combination of both factors. Mylodon was named by Richard Owen on the basis of a nearly complete lower jaw with teeth, which was found by Charles Darwin in a consolidated gravel cliff at Bahía Blanca , during the survey expedition of HMS Beagle . At several sites, preserved hide and dung have been discovered, and are in such a state of conservation that the people who first discovered them believed they belonged to
476-413: A comprehensive description. Characteristic of the skull was the narrow snout and a closed nasal arch, which was formed by the firm adhesion of the nasal bone to the middle jaw bone. Furthermore, the dentition consisted of a total of 16 teeth, the upper front canine-like tooth was reduced in each case, in the lower jaw, however, sat four molar-like teeth each. Reinhardt noticed similarities to M. darwinii in

On Christmas Eve 2003, the city as others in east central coast of Florida received snow from the ocean effect , when cold air passes over the considerably hotter ocean and causes the rise of air with higher temperature to bring moisture into the higher portions of the atmosphere . Tropical flora typical of more southerly locations is grown in
714-506: A greater fiber content. Such a digestive system could reduce the amount of processed food in the mouth and thus ultimately also have compensated for the small total chewing surface in Mylodon . Direct analysis of the food resources used is possible, among many other things, due to the numerous dung residues in the form of coprolites. These are available not only from the Cueva del Milodón in

Two years later, however, Owen discarded the name Glossotherium again. This occurred in the course of processing a nearly complete skeleton that had been discovered
952-693: A later stratum. In 1925 attention shifted to the Melbourne golf course. A crushed human skull with finger, arm, and leg bones was found in association with a horse tooth. A piece of ivory that appeared to have been modified by humans was found at the bottom of the stratum containing bones. Other finds included a spear point near a mastodon bone and a turtle-back scraper and blade found with bear, camel, mastodon, horse, and tapir bones. Similar human remains, Pleistocene animals and Paleo-Indian artifacts were found in Vero Beach , 30 miles (48 km) south of Melbourne, and similar Paleo-Indian artifacts were found at
1071-469: A living animal, instead of to an extinct species. The discovery of fresh-looking samples of skin and dung sparked a small wave of expeditions during the early 20th century to search for a living example of the animal. The samples have since been found to be around 10,000 years old, although they look fresh because of the extreme cold and stable conditions in the caves in which they were found. Well preserved samples of Mylodon remains have been discovered in

On parietal, significant temporal lines were present, but no head crest formed. The zygomatic arch was slim, the anterior attachment began above the third and fourth molars. It did not form
1309-521: A partially ossified nasal septum, it can be assumed that relatively high chewing forces acted when the food was chopped up. In contrast to the sometimes huge representatives of the Megatheriidae , the joint between the lower jaw and the skull of the Mylodonts was relatively low, roughly at the chewing level of the teeth. The resulting decreasing lever arm of the masseter muscle experiences through

Melbourne has a distinctly seasonal precipitation pattern, with a hot and wet season (late May through October) and a warm and dry season (November through April). The climate is strongly influenced by the nearby Atlantic Ocean and Gulf Stream, as well as incursions of cold fronts from
1785-412: A solid end with the rear arch attachment. As is usual with sloths, the front arch base consisted of three appendages: one ascending, one horizontal, and one descending, the former of which was the longest. The rear arch formed a triangular plate. The occiput bent at an angle of 120° from the roof of the skull. The underside of the occiput was at about the level of the occlusal plane. When viewed from behind,

It was drawn in on the shaft and widened at the joint ends, with the upper joint end showing more pronounced curves than in Glossotherium . The hand comprised a total of five digits (I to V), whereby the metacarpal bone was fused with the large polygonal bone on the first digit. This created
2023-528: A very slow metabolism concluded. The latter is the case with today's sloths. This is due to the long passage time of the food of up to a week through the large, multi-chambered stomach. It can be assumed that this also applies to the extinct sloths. Possibly this made the stomach of the mylodonts a functional equivalent to the complex stomach of the ruminants, whereby a long passage time of the food enabled efficient digestion, in which even more difficult to access nutrients could be provided, for example from foods with

The ungulates are mostly used as analogous examples, in which shapes with high tooth crowns and broad-lipped mouths are usually grass-eating, such as various cattle, horses or the white rhinoceros. In contrast, those with low tooth crowns and narrow snouts such as the duiker or the black rhinoceros feed largely selective from various leaves and other soft vegetable foods. In contrast to other large mylodontid sloths such as Glossotherium , Paramylodon or Lestodon ,

From a global perspective, numerous larger animals became extinct during the transition from the Pleistocene to the Holocene, which is why this event is considered a Quaternary extinction wave. In South America, this coincides with the first appearance of humans. Whether the two are causally related is the subject of much controversy. In addition to potential hunting and possible landscape overprinting by early human hunter-gatherer groups, climatic changes may also have had an influence.

He confirmed in 1889, the separation of both M. darwinii and M. robustus not only at the species level, but also at the genus level. Deviating from Reinhardt, but agreeing with Owen, he considered the mandible of M. darwinii and the skull fragment of Glossotherium to belong together. Since in this scenario Glossotherium possessed priority over Mylodon (Owen mentioned

Investigations of the plant residues showed 80 to 95% grasses and 5 to 20% sedges . Herbaceous plants, on the other hand, could only be detected in traces. Accordingly, Mylodon led, at least in southwestern Patagonia, a diet consisting almost exclusively of grasses. The food is reflected in

Mylodon chronologically overlapped with Paleoindians , the first humans to inhabit the Americas, evidence from several sites suggest that they may have hunted Mylodon . The extinction of Mylodon may be the result of climatic change, hunting by Paleoindians, or

During this period, the possibly closely related form Archaeomylodon also occurred in the Pampas region, whose foremost canine teeth of the upper dentition were greatly reduced in size, but not yet completely reduced. Among the early and more northerly finds of Mylodon is, for example, a skull from the El Palmar Formation in the Argentine province of Entre Ríos, which dates to

The majority of these attest to at least a coexistence of humans and ground sloths over an extended period of time. Direct associations of human cultural products and fossil remains of Mylodon are found, among others, at Gruta del Indio in the eastern foothills of the Andes, at Piedra Museo or Las Buitreras, all in Argentina, and at Tres Arroyos in Tierra del Fuego, respectively. Mylodon

Even more northerly points of discovery, such as Ñuapua in Bolivia, are tangent to the 20th parallel south. Finds reported from Paraguay, however, are considered rather uncertain. The first occurrence of Mylodon may have been in
4879-420: The Pampas, with the Patagonian remains belonging to the separate species Mylodon listai. The taxonomic history of Mylodon is complex. It has involved confusion and equivocation with other mylodont forms such as Glossotherium and Paramylodon over a long period of time. Some of this complexity can be attributed to the first describer of the genus itself, who is Richard Owen (1804-1892). Owen, one of

These include the important archaeological site of Paso Otero in Buenos Aires Province, the locality of Arroyo de Vizcaíno in southern Uruguay, and the Chuí River. As with many of the other large ground sloths, most of the Mylodon material is from the Upper Pleistocene, with a focus toward the end of the last glacial period. It

The upper data are among the most recent obtained directly from finds of the sloth vertebrate. Mylodon' s close relatives include the ground sloths of the genera Glossotherium and Paramylodon . The latter genus has often been confused with Glossotherium , but Paramylodon
5474-401: The angular process does not reach the occlusal plane. The dentition of Mylodon differs greatly from that of the other placental mammals and usually consists of five teeth at the top and four teeth at the bottom per jaw arch, meaning a total of 18 teeth. In the mylodonts, the first tooth was often caniniform while the rear teeth were more molariform . Within the sloth, this structure of

The extraordinary length of the skull of Mylodon was mainly due to elongations in the rostrum . Seen from above, the rostrum narrowed towards the front. This is where the most important difference to most of the other representatives of the Mylodontidae can be found: The nasal bone
5712-454: The armadillos' shells, the bone platelets form a single layer and do not appear stacked. Since all skin residues were found isolated from the body skeletons, it is sometimes difficult to assign the skin areas with a dense and thin arrangement of bone platelets to a specific part of the body. However, it can be assumed that the back was largely armored and the stomach was free. In the sections with dense osteoderm formation, these were larger than in

Mylodon was mainly distributed in the southern part of South America. Fossil finds are known from Argentina, Chile, southern Bolivia, Uruguay, Paraguay and southern Brazil. Thus, the colonized regions include very far southern sites on

On the surface, they showed individual dimples. In cross-section, they consisted of numerous bundles of fibers mixed with hard bone blades (osteoma). This made their structure much simpler than that of

Similar to other large ground sloths, the hand of Mylodon made contact with the ground with the outer side edge and thus sat up rotated. This is indicated by the long metacarpal bones of the external digits and the decreasing number of phalanges on them. The special hand position protected

8330-541: The land that was used for that program makes up most of what is currently the Melbourne Orlando International Airport . In 1969, the cities of Eau Gallie and Melbourne voted to merge, forming modern-day Melbourne. In the 1950s, Babcock Street was extended north to intersect with US 1. The Melbourne Shopping Center was constructed on Babcock, the area's first strip mall . Consumers were sufficiently attracted to this new mall, that
8449-405: The large ground sloths is even more difficult. One piece of evidence is often considered to be Quebrada de Quereo, a site on an ancient coastline in northern Chile. From here come, among other things, skeletal remains of two individuals of Mylodon , distributed in each case over a narrowly defined area, but in two different stratigraphic units and at a spatial distance of 21 m from each other. One of
8568-421: The last molar and formed an angle of 140° to the occlusal plane. The crown process rose up to 20 cm. In contrast, the articular process was lower, roughly at the level of the occlusal plane, resulting in a low cranial-mandibular connection. The angular process at the rear end of the lower jaw was clearly visible. Sometimes it tipped down and was below the lower edge of the horizontal bone body. The upper side of
8687-431: The laterally elongated head of which did not allow any major rotational movements. These features can be interpreted as adaptations to a purely terrestrial lifestyle. Finally, the muscle attachment points on the first cervical vertebra referenced, which are more developed than for example with Paramylodon . Correspondingly, the occipital joint surfaces are also somewhat further apart. Both can be interpreted as meaning that
8806-454: The long claws of the inner digits, which did not penetrate the ground while walking. A functionally similar but fundamentally different hand position can be found in the ankle duct of the distantly related present-day great anteater. The elbow joint was pointed slightly outwards when standing on four feet and the arms were thus angled slightly inwards, which is evident from the position of the olecranon yields. The hands came to rest slightly within
8925-419: The lower ones had retained their strikingly pointed shape. In contrast to this, Glossotherium and Lestodon had the original decayed teeth. The flat, flap-like and largely indented structure of the molariform teeth can be emphasized as a characteristic of the mylodonts, which clearly differs from that of the Megatheriidae and Megalonychidae with their two transverse raised ridges per tooth. The shapes of
9044-410: The mandible of M. darwinii with Reinhardt's Grypotherium and subsequently recovered Grypotherium darwinii . Smith Woodward assigned the skull fragment of Glossotherium to M. robustus by analogy with Reinhardt. The mylodontids (particularly Mylodon itself) are often considered to be pronounced grazers because of their dental structure with flat chewing surfaces on the molar-like teeth. This
9163-441: The masseter and musculus pterygoideus to a limited extent. It can therefore be assumed that forwards and backwards directed chewing movements dominated in Mylodon . The flat tooth crowns lead to a comparatively small size of the total available chewing surface. In Mylodon , this amounts to a good 1320 mm corresponding to other mylodonts of the same size. The Indian rhinoceros, which is comparable in terms of its dimensions, has, on
9282-552: The molar-like teeth (from Greek μυλη ( myle ) for "molar" and ὀδούς ( odoús ) for "tooth", thus translating as much as "molar tooth"), with the species epithet darwinii honoring Darwin as finder of the voucher specimen . As a second species besides M. darwinii Owen referred in his paper to M. harlani . This form was based on a mandible and clavicle, both of which came from the Big Bone Lick in Boone County in
9401-548: The most important explorers of the Victorian era, was concerned from 1836 with fossil finds brought back by Charles Darwin from his pioneering voyage on HMS Beagle to South America . The collection also included a mandible from Punta Alta near Bahía Blanca in the south of the Argentina Buenos Aires Province (specimen number NHM 16617). The nearly complete specimen was distinguished by
9520-414: The mouth of Mylodon is relatively narrow. A special feature is the closed nasal arch, which is heavily roughened in its front area and thus offers muscle attachment points for a mobile upper lip. Something similar can be said about individual depressions in the vicinity of the infraorbital foramen, which also functioned as starting points for individual muscle strands in the nose and lip area. Maybe Mylodon
9639-452: The name could be applied to almost any extinct mammalian form because almost all of them had the posterior molars. Moreover, the name would be inappropriate because, starting from the Latin version dens molaris for "molar tooth" and the second part of speech don (from dens for "tooth"), there is a duplication that would translate as "molar tooth-tooth". Regardless, Owen's establishment of
9758-455: The new species M. robustus. The skull fragment that he had originally placed in Glossotherium he now associated with M. darwinii . As a result of this study, three species of the genus Mylodon already existed in the 1840s. A skull including mandible found at Pergamino in Buenos Aires Province served the Danish zoologist Johannes Theodor Reinhardt (1816-1882) in 1879 as the basis for
9877-549: The north in winter months. Melbourne averages 51 inches (1,300 mm) of rainfall annually, much of it coming in convective thunderstorms in the late May to early October time period. The record rainfall occurred on August 20, 2008, when Tropical Storm Fay dropped 18.21 inches (463 mm). Melbourne can sometimes have moderate to severe drought conditions from late fall through spring, with brush fires occurring and water restrictions put in place. Melbourne averages 2 days per year with frost, although several years might pass without
9996-486: The occiput appeared almost circular and not as depressed as in Glossotherium and Lestodon . The palate was narrow and was more or less triangularly oriented towards the front of the skull. Numerous small bone openings were characteristic here. The glenoid pit, in which the joint of the lower jaw engages, corresponding to that of other mylodonts with its weak form, but this provided free rotation overall. The lower jaw of Mylodon varied in length between 42 and 48 cm. It
10115-410: The other hand, double to four times the value with 2660 to 5190 mm . The situation is similar with the hippopotamus, the total surface area of which is between 3290 and 5410 mm . The small total occlusal surface of the teeth in Mylodon probably resulted in a rather low processing capacity for the food in the mouth. This can result in either a high rate of fermentation in the gastrointestinal tract and/or
10234-412: The other large ground-living sloths. Especially in the construction of the skull, Mylodon differed significantly from other related forms. Its length varied between 59 and 71.5 cm, which is significantly longer than Glossotherium or Lestodon . At the skull it was between 16.5 and 22.5 cm wide, in the front nasal area between 11.3 and 15.5 cm. The height of the posterior skull was 14.0 to 19.0 cm and
10353-415: The outer armor of the armadillos, the bone platelets of the mylodonts were rather loosely scattered. Hermann Burmeister published the first finds of individual osteoderms of Mylodon as early as the 1860s. The remains of skin found in the caves of Última Esperanza give an impression of how they were embedded in the skin and distributed over the body. The bone platelets are all located in the lower section of
10472-452: The paleohabitat, as pollen analyzes show that the landscape at that time was tundra-like in character and was therefore almost free of trees with only a few low bushes. Occasional evidence of false beeches is interpreted as pollen carried by the wind. A 2021 study on stable isotope ratios concluded that Mylodon must have been at least sporadically omnivorous. In general, large mylodonts are ground-dwelling animals. The lower section of
10591-474: The same stratum mammoth, mastodon , horse, ground sloth , tapir , peccary , camel , and saber-tooth cat bones, all extinct in Florida since the end of the Pleistocene 10,000–8,000 BCE. At a nearby site a human rib and charcoal were found in association with Mylodon , Megalonyx , and Chlamytherium (ground sloth) teeth. A finely worked spear point found with these items may have been displaced from
10710-427: The second was about 4.2 cm long and the third at least 11.5 cm. It was tubular and went forward into an extension on which the claw rested. The first phalanges of the two outer digits were significantly reduced in length. Only individual root bones of the foot, such as the talus, are present. Mylodon is one of the few extinct mammals that has mummified skin remains. The most important location for such finds
10829-399: The shaft, the lowest value was reached just below the midpoint. Here the width was about 18 cm, the thickness about 7.5 cm. The joint ends, on the other hand, were markedly wider, around 30 cm at the knee end and around 26 cm at the foot end. The thighbone reached the shin with only about half of its length, a characteristic of mylodonts. This bone, too, was clearly flat with
10948-466: The size of Melbourne. Streetlights were gradually added until, by the early 1960s, streets east of Babcock Street had lights. Lights were added to streets west of Babcock after the early 1960s. In 1969, the city elected Julius Montgomery , its first black councilman. Montgomery was also the first African American student of Brevard Engineering College, later Florida Institute of Technology which named their Pioneer Award after him. On August 2, 1995,
11067-432: The skin, while the hairs originate in the upper sections. The distribution turned out to be very inconsistent. Some areas with a dense array of osteoderms contain between 83 and 95 platelets per 10 cm . For others, however, the number is very thin. However, even with a close arrangement, the osteoderms never unite to form a closed shell, but are always separated from one another by individual skin folds. In accordance with
11186-399: The so-called Metacrapal Carpal Complex (MCC for short), which is typical for many ground sloths. As a special feature of the wrist, the pea bone was clearly flat, its shape resembled that of Glossotherium , but differed from the corresponding bone of other Mylodonts with spherical, walnut-like or a pyramidal shape. The fourth digit had formed the longest metacarpal bone, while that of the fifth
11305-499: The standalone MFD market when they certified their first Flight Situation Display system in 1997. Avidyne's FlightMax Entegra line was first released in 2003 in the Cirrus SR22 —the first big-glass flight deck system for light general aviation aircraft. On November 3, 2005, Avidyne Corporation and Ryan International Company announced a merger of the two companies. Ryan International was founded in 1981 by CEO Paul Ryan, inventor of
11424-401: The structure of the zygomatic arch, mainly of the descending process, a certain compensation, so that there should have been only minor differences to the Megatheria with regard to the biting force. The extended mandibular joint allows a wide freedom of movement when chewing. Against this, however, is the zygomatic arch, which is not closed and therefore could only withstand the opposing forces of
11543-449: The teeth can be called original. A special feature of Mylodon was that the upper canine-like tooth of each row was completely regressed and only the molar-like four rear teeth were found here. In the lower row of teeth, the anterior caniniform tooth was transformed into a molariform. The dentition thus consisted of a total of 16 teeth. This is somewhat reminiscent of Paramylodon , in which the upper canine-shaped teeth were also missing, but
11662-409: The teeth present in Mylodon were simpler. In the upper jaw row, they had a rather round to oval outline, in the lower jaw row a more diamond -shaped outline. The typically more complex bilobed design of the molar-like teeth of Glossotherium and Lestodon , caused by a central constriction, only occurred on the lower rearmost tooth in Mylodon . In general, the rows of teeth diverged to the front, and
11781-444: The teeth were very high crowned ( hypsodont ). The upper row of teeth ranges in length from 10.9 to 13.3 cm, the lower row was between 12.0 and 15.0 cm in length. Postcranial skeletons are far rarer in Mylodon than in the other large mylodontid sloths. As a result, the skeleton is less well documented. Only individual elements of the spine, such as the atlas and various thoracic vertebrae, have been described. The humerus
11900-479: The top hair being developed, while the undercoat is missing. This feature is similar to the two-toed sloths but less so than the three-toed sloths , which possess an undercoat. The length of the individual hairs vary between 5 and sometimes over 20 cm with the shortest in the area of the back of the head, medium-length hair on the back and very long hair on the limbs. Their known color ranges from yellowish to reddish-brown. The hair shafts are uniformly tubular, at
12019-574: The total population spoke languages other than English. The Melbourne City Council consists of the mayor and six district council members. Melbourne uses a Council-Manager form of government . City officials The following are appointed by the council: Melbourne city officials created the Babcock Street Redevelopment District in 1998 to stimulate new development along Babcock Street from U.S. 1 south to U.S. 192 . A 218-unit apartment complex built in 2005
12138-586: The traditional downtown, off New Haven, suffered. Urban blight was successfully mitigated in the 1980s. A board was created by the legislature to spend a 10% tax on electric bills. This was used by the Melbourne Civic Improvement Board to build the Melbourne Auditorium, the first library and fire station, and various parks. The board was dissolved when Melbourne was merged with Eau Gallie in 1969. That merger doubled
12257-416: The upper end they form blunt tips. As with today's sloths, the hair did not have a pith (medulla). In contrast to the hair of the two-toed sloth, they lack their characteristic longitudinal ribbing. The mylodonts are the only representatives of the sloths to have bony plates embedded in their skin. Such structures, called osteoderms , are known today to a greater extent only in armadillos. In contrast to
12376-416: The width of the elbow. Such an orientation of the arms can effectively support the large mass of Mylodon . As a result, the hands would also be in a line with the feet, which is also conveyed, among other things, by footprints from Paramylodon . The laterally limited articular surface of the femoral head severely restricted the mobility of the hindlimbs. The same applies to the forearm, the straight spoke with
12495-464: The year before in the flood plains of the Río de la Plata north of Buenos Aires . The largely intact skull was characterized by a short and broad snout and by a dentition consisting of a total of 18 teeth, of which the foremost tooth in each case showed a canine design. Based on the similarities in dental structure with the flat, molar-like teeth, Owen placed the skeleton in the genus Mylodon and introduced
12614-466: Was 65 years of age or older. The average household size was 2.22 and the average family size was 2.82. In 2000, the city the population was spread out, with 20.7% under the age of 18, 9.3% from 18 to 24, 28.4% from 25 to 44, 21.9% from 45 to 64, and 19.7% who were 65 years of age or older. The median age was 40 years. For every 100 females, there were 94.3 males. For every 100 females age 18 and over, there were 91.1 males. As of 2000, per capita income for
12733-493: Was a large representative of the Mylodontidae . Its total length was estimated to be around 3 to 4 m. Based on the size of the skull, a weight between 1 and 2 tonnes is assumed, with an approximate estimate of 1.65 tonnes. Thus, Mylodon had about the size of related forms such as Glossotherium or Paramylodon , but was significantly smaller than the giant Lestodon . In terms of physique, it largely corresponded with
12852-470: Was among the top 20 in home price appreciation from 2003 to 2004. In 2009, Forbes ranked the area 18th out of 100 Metropolitan Statistical Areas and first out of 8 metros in Florida for affordable housing, and short commute times, among others. Melbourne has two downtown business districts, a result of the merger of Eau Gallie into Melbourne: The city has three hospitals, day care for senior citizens, hospice, walk-in, and urgent care facilities. There
12971-479: Was caused by a massive internal epicondyle. The articular surfaces (capitulum and trochlea) were almost perpendicular to each other and did not form such an obtuse angle as in Glossotherium . The cubit was built gracefully. Their length was around 37 cm. The olecranon, i.e. the upper articular process, took up about 8.1 cm of it, which corresponds to about 22% of the total length and is significantly less than in comparison with Glossotherium and Lestodon . It
13090-607: Was described by Richard Owen in 1840 based on remains collected in the Pampas by Charles Darwin (for whom the species is named) during the Voyage of the Beagle . Some recent authors suggest that there were two species, with M. darwini restricted to the Pampas, with the Patagonian remains belonging to the separate species Mylodon listai. Mylodon went extinct at the end of the Late Pleistocene-beginning of
13209-416: Was elongated, more noticeable than in Glossotherium and Lestodon , since in Mylodon the area in front of the teeth, in particular, is strongly elongated. The horizontal bone body increased continuously in height towards the rear, below the last molar it was about 10.5 to 12.7 cm. The symphysis at the front end for the jointing of the two halves of the lower jaw was about 12.4 cm long. Here the lower edge of
13328-487: Was founded in 1885 and is still active. In the late 1890s, the Brownlie-Maxwell Funeral Home opened and it is still in business. The oldest black-owned business in the county is Tucker's Cut-Rate plumbing. It opened in 1934. In the early 1900s, houses were often built in the frame vernacular style. In 1919, a fire destroyed most of the original downtown along Front Street. At the time, it
13447-562: Was in turn named after the British Prime Minister William Lamb, 2nd Viscount Melbourne ). He is buried in the Melbourne Cemetery , along with many early residents in the area. The first school in Melbourne was built in 1883 and is on permanent exhibit on the campus of Florida Institute of Technology . By 1885, the town had 70 people. The Greater Allen Chapel African Methodist Episcopal Church
13566-526: Was laterally narrowed, which is also found in Paramylodon . The spoke largely resembled that of Glossotherium and was compact and straight built with a length of about 30 cm. The head was oval in shape with a prominent lip. The pelvis was extremely expansive and 114 cm wide between the two iliac bones. The thigh bone measured between 55 and 59 cm in length. It was typical of ground sloths, being flat in shape. Its width decreased significantly on
13685-402: Was long and narrow and curved downwards in the front area. At the front end, it connected to the middle jawbone, which was lengthened by an appendage, and which in turn fused with the upper jaw. This resulted in a completely closed nasal arch in adult individuals, which is largely unknown in other sloths. In comparison, the skulls of Glossotherium and Lestodon , but also of Paramylodon , showed
13804-429: Was massive and extremely long at 46 to 48 cm. The joint head, the diameter of which was over 10 cm, stood out due to its hemispherical, but laterally somewhat flattened shape. A distinct deltopectoral ridge ran down the shaft, which acted as an anchor point for the shoulder muscles. As with many ground sloths, the lower end of the joint extended far and brought it here to a width of almost 26 cm. In part, this
13923-400: Was more well-adapted to a mixed-vegetation diet, which was picked up with the help of a movable upper lip. The loss of the front teeth in the upper row of teeth also leads to the assumption that, comparable to cattle, there was a horn-like structure on the middle jawbone that could be used to pluck the food. The entire anterior cranial structure of Mylodon is relatively solid, combined with
14042-407: Was only slightly shorter. The respective bones measured there around 12.5 and 10.7 cm in length. As with Glossotherium and Paramylodon , only the three inner digits were probably clawed, but only of the second digit have all bone elements been documented. The metacarpal bone was 7.8 cm long and was built very gracefully. The first phalanx was extremely short and only about 2.5 cm long,
14161-621: Was rebuilt west of US Hwy 1. During the Jim Crow years, black people were required to enter movie theaters via a different entrance from whites and sit in the balcony. Gas stations had signs for rest rooms labeled "Men", "Women", and "Colored." This persisted until integration in the late 1960s. In late 1942 the Naval Air Station Melbourne was established as a site to train newly commissioned Navy and Marine pilots for World War II . The program ran until 1946, and
