The evolving co-dependence of insects and seed plants that characterized a recognizably modern world had its genesis in the Late Devonian Epoch. The development of soils and plant root systems probably led to changes in the speed and pattern of erosion and sediment deposition. The rapid evolution of

The climate would have affected the dominant organisms in reefs ; microbes would have been the main reef-forming organisms in warm periods, with corals and stromatoporoid sponges taking the dominant role in cooler times. The warming at the end of the Devonian may even have contributed to the extinction of the stromatoporoids. At

Other rare species recorded in Devon include seahorses and the sea daffodil. The botany of the county is very diverse and includes some rare species not found elsewhere in the British Isles other than Cornwall. Devon is divided into two Watsonian vice-counties : north and south,

This formation stretches from Bideford to Bude in Cornwall, and contributes to a gentler, greener, more rounded landscape. It is also found on the western, north and eastern borders of Dartmoor. The sedimentary rocks in more eastern parts of the county include Permian and Triassic sandstones (giving rise to east Devon's well known fertile red soils); Bunter pebble beds around Budleigh Salterton and Woodbury Common and Jurassic rocks in
1260-664: A terrestrial ecosystem that contained copious animals opened the way for the first vertebrates to seek terrestrial living. By the end of the Devonian, arthropods were solidly established on the land. The Late Devonian extinction is not a single event, but rather is a series of pulsed extinctions at the Givetian-Frasnian boundary, the Frasnian-Famennian boundary, and the Devonian-Carboniferous boundary. Together, these are considered one of

The island arcs of the region, such as the Balkhash-West Junggar Arc, exhibited biological endemism as a consequence of their location. Siberia was located just north of the equator as the largest landmass in the Northern Hemisphere. At the beginning of the Devonian, Siberia was inverted (upside down) relative to its modern orientation. Later in

Later, the area began to experience Saxon incursions from
5796-710: The Armorican Terrane Assemblage, split away from Gondwana in the Silurian and drifted towards Laurussia through the Devonian. Their collision with Laurussia leads to the beginning of the Variscan Orogeny , a major mountain-building event which would escalate further in the Late Paleozoic. Franconia and Saxothuringia collided with Laurussia near the end of the Early Devonian, pinching out the easternmost Rheic Ocean. The rest of

This sequence of rifting and collision events led to the successive creation and destruction of several small seaways, including the Rheno-Hercynian, Saxo-Thuringian, and Galicia-Moldanubian oceans. Their sediments were eventually compressed and completely buried as Gondwana fully collided with Laurussia in

Marine faunas continued to be dominated by conodonts, bryozoans , diverse and abundant brachiopods , the enigmatic hederellids , microconchids , and corals . Lily-like crinoids (animals, their resemblance to flowers notwithstanding) were abundant, and trilobites were still fairly common. Bivalves became commonplace in deep water and outer shelf environments. The first ammonites also appeared during or slightly before

9324-661: The beginning of the Mississippian subperiod of the Carboniferous. In 19th-century texts the Devonian has been called the "Old Red Age", after the red and brown terrestrial deposits known in the United Kingdom as the Old Red Sandstone in which early fossil discoveries were found. Another common term is "Age of the Fishes", referring to the evolution of several major groups of fish that took place during
9450-530: The boundary being an irregular line approximately across the higher part of Dartmoor and then along the canal eastwards. Botanical reports begin in the 17th century and there is a Flora Devoniensis by Jones and Kingston in 1829. A general account appeared in The Victoria History of the County of Devon (1906), and a Flora of Devon was published in 1939 by Keble Martin and Fraser. An Atlas of
9576-437: The coat of arms, but following the loss in 1998 of Plymouth and Torbay re-adopted the coat of arms. In April 2006 the council unveiled a new logo which was to be used in most everyday applications, though the coat of arms will continue to be used for "various civic purposes". Devon also has its own flag which has been dedicated to Saint Petroc, a local saint with dedications throughout Devon and neighbouring counties. The flag
9702-684: The continent (such as Greenland and Ellesmere Island ) established tropical conditions, most of the continent was located within the natural dry zone along the Tropic of Capricorn , which (as nowadays) is a result of the convergence of two great air-masses, the Hadley cell and the Ferrel cell . In these near-deserts, the Old Red Sandstone sedimentary beds formed, made red by the oxidised iron ( hematite ) characteristic of drought conditions. The abundance of red sandstone on continental land also lends Laurussia
9828-548: The continents Laurentia (modern day North America) and Baltica (modern day northern and eastern Europe). The tectonic effects of this collision continued into the Devonian, producing a string of mountain ranges along the southeastern coast of the continent. In present-day eastern North America, the Acadian Orogeny continued to raise the Appalachian Mountains . Further east, the collision also extended
9954-421: The county has attractive rolling rural scenery and villages with thatched cob cottages. All these features make Devon a popular holiday destination. In South Devon the landscape consists of rolling hills dotted with small towns, such as Dartmouth , Ivybridge , Kingsbridge , Salcombe , and Totnes . The towns of Torquay and Paignton are the principal seaside resorts on the south coast. East Devon has
10080-592: The county is ranked fourth by area (due to the creation of Cumbria) amongst ceremonial counties and is the third largest non-metropolitan county . The island of Lundy and the reef of Eddystone are also in Devon. The county has more mileage of road than any other county in England. Inland, the Dartmoor National park lies wholly in Devon, and the Exmoor National Park lies in both Devon and Somerset. Apart from these areas of high moorland
10206-598: The diocese of Wessex, while nothing is known of the church organisation of the Celtic areas. About 703 Devon and Cornwall were included in the separate diocese of Sherborne and in 900 this was again divided into two, the Devon bishop having from 905 his seat at Tawton (now Bishop's Tawton ) and from 912 at Crediton , birthplace of St Boniface. Lyfing became Bishop of Crediton in 1027 and shortly afterwards became Bishop of Cornwall . The two dioceses of Crediton and Cornwall, covering Devon and Cornwall, were united under Edward
10332-405: The early Devonian Period around 400 Ma. Bactritoids make their first appearance in the Early Devonian as well; their radiation, along with that of ammonoids, has been attributed by some authors to increased environmental stress resulting from decreasing oxygen levels in the deeper parts of the water column. Among vertebrates, jawless armored fish ( ostracoderms ) declined in diversity, while
10458-568: The east around 600 AD, firstly as small bands of settlers along the coasts of Lyme Bay and southern estuaries and later as more organised bands pushing in from the east. Devon became a frontier between Brittonic and Anglo-Saxon Wessex, and it was largely absorbed into Wessex by the mid ninth century. A genetic study carried out by the University of Oxford & University College London discovered separate genetic groups in Cornwall and Devon. Not only were there differences on either side of
10584-641: The east bank of the River Tamar in 936 AD. Danish raids also occurred sporadically along many coastal parts of Devon between around 800AD and just before the time of the Norman conquest, including the silver mint at Hlidaforda Lydford in 997 and Taintona (a settlement on the Teign estuary) in 1001. Devon was the home of a number of anticlerical movements in the Later Middle Ages . For example,
10710-662: The east. Major tectonic events include the closure of the Rheic Ocean , the separation of South China from Gondwana, and the resulting expansion of the Paleo-Tethys Ocean . The Devonian experienced several major mountain-building events as Laurussia and Gondwana approached; these include the Acadian Orogeny in North America and the beginning of the Variscan Orogeny in Europe. These early collisions preceded
10836-544: The easternmost parts of Devon. Smaller outcrops of younger rocks also exist, such as Cretaceous chalk cliffs at Beer Head and gravels on Haldon, plus Eocene and Oligocene ball clay and lignite deposits in the Bovey Basin, formed around 50 million years ago under tropical forest conditions. Devon generally has a cool oceanic climate, heavily influenced by the North Atlantic Drift . In winter, snow
10962-569: The end of the Devonian, the first seed-forming plants had appeared. This rapid appearance of many plant groups and growth forms has been referred to as the Devonian Explosion or the Silurian-Devonian Terrestrial Revolution. The 'greening' of the continents acted as a carbon sink , and atmospheric concentrations of carbon dioxide may have dropped. This may have cooled the climate and led to
11088-412: The equator to the poles was not as large as it is today. The weather was also very arid, mostly along the equator where it was the driest. Reconstruction of tropical sea surface temperature from conodont apatite implies an average value of 30 °C (86 °F) in the Early Devonian. Early Devonian mean annual surface temperatures were approximately 16 °C. CO 2 levels dropped steeply throughout
11214-632: The first seaside resort to be developed in the county, Exmouth and the more upmarket Georgian town of Sidmouth , headquarters of the East Devon District Council. Exmouth marks the western end of the Jurassic Coast World Heritage Site . Another notable feature is the coastal railway line between Newton Abbot and the Exe Estuary: the red sandstone cliffs and sea views are very dramatic and in
11340-459: The formation of the single supercontinent Pangaea in the Late Paleozoic. The period is named after Devon , a county in southwestern England, where a controversial argument in the 1830s over the age and structure of the rocks found throughout the county was resolved by adding the Devonian Period to the geological timescale. The Great Devonian Controversy was a lengthy debate between Roderick Murchison , Adam Sedgwick and Henry De la Beche over
11466-492: The free water column as well as high ecological competition in benthic habitats, which were extremely saturated; this diversification has been labeled the Devonian Nekton Revolution by many researchers. However, other researchers have questioned whether this revolution existed at all; a 2018 study found that although the proportion of biodiversity constituted by nekton increased across the boundary between
11592-581: The home of the Dumnonii Celtic Britons . The Anglo-Saxon settlement of Britain resulted in the partial assimilation of Dumnonia into the kingdom of Wessex in the eighth and ninth centuries, and the western boundary with Cornwall was set at the Tamar by king Æthelstan in 936. The name Devon derives from the name of the Brythons who inhabited the southwestern peninsula of Britain at
11718-744: The increased overall diversity of nekton in the Devonian to a broader, gradual trend of nektonic diversification across the entire Palaeozoic. A now-dry barrier reef, located in present-day Kimberley Basin of northwest Australia , once extended 350 km (220 mi), fringing a Devonian continent. Reefs are generally built by various carbonate -secreting organisms that can erect wave-resistant structures near sea level. Although modern reefs are constructed mainly by corals and calcareous algae , Devonian reefs were either microbial reefs built up mostly by autotrophic cyanobacteria or coral-stromatoporoid reefs built up by coral-like stromatoporoids and tabulate and rugose corals . Microbial reefs dominated under
11844-425: The increasing competition, predation, and diversity of jawed fishes . The shallow, warm, oxygen-depleted waters of Devonian inland lakes, surrounded by primitive plants, provided the environment necessary for certain early fish to develop such essential characteristics as well developed lungs and the ability to crawl out of the water and onto the land for short periods of time. Finally, the Late Devonian started with
11970-403: The jawed fish (gnathostomes) simultaneously increased in both the sea and fresh water . Armored placoderms were numerous during the early ages of the Devonian Period and became extinct in the Late Devonian, perhaps because of competition for food against the other fish species. Early cartilaginous ( Chondrichthyes ) and bony fishes ( Osteichthyes ) also become diverse and played a large role within
12096-481: The land lay under shallow seas, where tropical reef organisms lived. The enormous "world ocean", Panthalassa , occupied much of the Northern Hemisphere as well as wide swathes east of Gondwana and west of Laurussia. Other minor oceans were the Paleo-Tethys Ocean and Rheic Ocean . By the early Devonian, the continent Laurussia (also known as Euramerica ) was fully formed through the collision of
12222-575: The low, carpet-like vegetation during the early part of the Devonian. Also, the first possible fossils of insects appeared around 416 Ma, in the Early Devonian. Evidence for the earliest tetrapods takes the form of trace fossils in shallow lagoon environments within a marine carbonate platform/shelf during the Middle Devonian, although these traces have been questioned and an interpretation as fish feeding traces ( Piscichnus ) has been advanced. Many Early Devonian plants did not have true roots or leaves like extant plants, although vascular tissue
12348-645: The main centres of surfing in Britain. A geological dividing line cuts across Devon roughly along the line of the Bristol to Exeter line and the M5 motorway east of Tiverton and Exeter. It is a part of the Tees–Exe line broadly dividing Britain into a southeastern lowland zone typified by gently dipping sedimentary rocks and a northwestern upland zone typified by igneous rocks and folded sedimentary and metamorphic rocks . The principal geological components of Devon are i)
12474-616: The mid-fourth century AD, Christianity was introduced to Devon. In the Sub-Roman period the church in the British Isles was characterised by some differences in practice from the Latin Christianity of the continent of Europe and is known as Celtic Christianity ; however it was always in communion with the wider Roman Catholic Church . Many Cornish saints are commemorated also in Devon in legends, churches and place-names. Western Christianity came to Devon when it
12600-562: The name "the Old Red Continent". For much of the Devonian, the majority of western Laurussia (North America) was covered by subtropical inland seas which hosted a diverse ecosystem of reefs and marine life. Devonian marine deposits are particularly prevalent in the midwestern and northeastern United States. Devonian reefs also extended along the southeast edge of Laurussia, a coastline now corresponding to southern England , Belgium , and other mid-latitude areas of Europe. In
12726-625: The naming of the period. Murchison and Sedgwick won the debate and named it the Devonian System. While the rock beds that define the start and end of the Devonian Period are well identified, the exact dates are uncertain. According to the International Commission on Stratigraphy , the Devonian extends from the end of the Silurian 419.2 Ma, to the beginning of the Carboniferous 358.9 Ma – in North America , at
12852-411: The nearby microcontinent of Amuria (now Manchuria , Mongolia and their vicinities). Though certainly close to Siberia in the Devonian, the precise location of Amuria is uncertain due to contradictory paleomagnetic data. The Rheic Ocean, which separated Laurussia from Gondwana, was wide at the start of the Devonian, having formed after the drift of Avalonia away from Gondwana. It steadily shrunk as
12978-461: The old Roman walls of Exeter, are nearly always near the coast, as in those days travelling was done mainly by sea. The Devonian villages of Petrockstowe and Newton St Petroc are also named after Saint Petroc and the flag of Devon is dedicated to him. The history of Christianity in the South West of England remains to some degree obscure. Parts of the historic county of Devon formed part of
13104-401: The oldest known plants with woody tissue. By the Middle Devonian, shrub-like forests of primitive plants existed: lycophytes , horsetails , ferns , and progymnosperms evolved. Most of these plants had true roots and leaves, and many were quite tall. The earliest-known trees appeared in the Middle Devonian. These included a lineage of lycopods and another arborescent, woody vascular plant,
13230-703: The order Agoniatitida , which in later epochs evolved to new ammonoid orders, for example Goniatitida and Clymeniida . This class of cephalopod molluscs would dominate the marine fauna until the beginning of the Mesozoic Era. The Middle Devonian comprised two subdivisions: first the Eifelian , which then gave way to the Givetian 387.7 Ma. During this time the jawless agnathan fishes began to decline in diversity in freshwater and marine environments partly due to drastic environmental changes and partly due to
13356-403: The period continued, as the two major continents approached near the equator in the early stages of the assembly of Pangaea . The closure of the Rheic Ocean began in the Devonian and continued into the Carboniferous. As the ocean narrowed, endemic marine faunas of Gondwana and Laurussia combined into a single tropical fauna. The history of the western Rheic Ocean is a subject of debate, but there
13482-472: The period it moved northwards and began to twist clockwise, though it was not near its modern location. Siberia approached the eastern edge of Laurussia as the Devonian progressed, but it was still separated by a seaway, the Ural Ocean . Although Siberia's margins were generally tectonically stable and ecologically productive, rifting and deep mantle plumes impacted the continent with flood basalts during
13608-529: The period. Older literature on the Anglo-Welsh basin divides it into the Downtonian, Dittonian, Breconian, and Farlovian stages, the latter three of which are placed in the Devonian. The Devonian has also erroneously been characterised as a "greenhouse age", due to sampling bias : most of the early Devonian-age discoveries came from the strata of western Europe and eastern North America , which at
13734-522: The resorts railway line and beaches are very near. North Devon is very rural with few major towns except Barnstaple , Great Torrington , Bideford and Ilfracombe . Devon's Exmoor coast has the highest cliffs in southern Britain, culminating in the Great Hangman , a 318 m (1,043 ft) "hog's-back" hill with a 250 m (820 ft) cliff-face, located near Combe Martin Bay. Its sister cliff
13860-613: The rise of the Caledonian Mountains of Great Britain and Scandinavia . As the Caledonian Orogeny wound down in the later part of the period, orogenic collapse facilitated a cluster of granite intrusions in Scotland. Most of Laurussia was located south of the equator, but in the Devonian it moved northwards and began to rotate counterclockwise towards its modern position. While the most northern parts of
13986-628: The terminus of the Devonian, Earth rapidly cooled into an icehouse , marking the beginning of the Late Paleozoic icehouse . The Devonian world involved many continents and ocean basins of various sizes. The largest continent, Gondwana , was located entirely within the Southern Hemisphere . It corresponds to modern day South America , Africa , Australia , Antarctica , and India , as well as minor components of North America and Asia . The second-largest continent, Laurussia,
14112-571: The time of the Roman conquest of Britain known as the Dumnonii , thought to mean 'deep valley dwellers' from Proto-Celtic * dubnos 'deep'. In the Brittonic languages , Devon is known as Welsh : Dyfnaint , Breton : Devnent and Cornish : Dewnens , each meaning 'deep valleys'. (For an account of Celtic Dumnonia , see the separate article.) Among the most common Devon placenames
14238-535: The time straddled the Equator as part of the supercontinent of Euramerica where fossil signatures of widespread reefs indicate tropical climates that were warm and moderately humid. In fact the climate in the Devonian differed greatly during its epochs and between geographic regions. For example, during the Early Devonian, arid conditions were prevalent through much of the world including Siberia, Australia, North America, and China, but Africa and South America had
14364-599: The traditional orchard-visiting Wassail in Whimple every 17 January, and the carrying of flaming tar barrels in Ottery St. Mary , where people who have lived in Ottery for long enough are called upon to celebrate Bonfire Night by running through the village (and the gathered crowds) with flaming barrels on their backs. Berry Pomeroy still celebrates Queene's Day for Elizabeth I . Devon's total economic output in 2019
14490-521: The warmer conditions of the early and late Devonian, while coral-stromatoporoid reefs dominated during the cooler middle Devonian. By the Devonian Period, life was well underway in its colonization of the land. The moss forests and bacterial and algal mats of the Silurian were joined early in the period by primitive rooted plants that created the first stable soils and harbored arthropods like mites , scorpions , trigonotarbids and myriapods (although arthropods appeared on land much earlier than in
14616-555: The world saw the disappearance of an estimated 96% of vertebrates like conodonts and bony fishes , and all of the ostracoderms and placoderms. Land plants as well as freshwater species, such as our tetrapod ancestors, were relatively unaffected by the Late Devonian extinction event (there is a counterargument that the Devonian extinctions nearly wiped out the tetrapods ). The reasons for the Late Devonian extinctions are still unknown, and all explanations remain speculative. Canadian paleontologist Digby McLaren suggested in 1969 that
14742-537: Was adopted in 2003 after a competition run by BBC Radio Devon . The winning design was created by website contributor Ryan Sealey, and won 49% of the votes cast. The colours of the flag are those popularly identified with Devon, for example, the colours of the University of Exeter , the rugby union team, and the Green and White flag flown by the first Viscount Exmouth at the Bombardment of Algiers (now on view at
14868-472: Was approved by both Devon County Council and Torbay Council to create a Combined County Authority with various powers such as transport, housing, skills, and support for business devolved from the UK Government. The main settlements in Devon are the cities of Plymouth, a historic port now administratively independent, Exeter, the county town , and Torbay , the county's tourist centre. Devon's coast
14994-680: Was by far the largest continent on the planet. It was completely south of the equator, although the northeastern sector (now Australia) did reach tropical latitudes. The southwestern sector (now South America) was located to the far south, with Brazil situated near the South Pole . The northwestern edge of Gondwana was an active margin for much of the Devonian, and saw the accretion of many smaller land masses and island arcs. These include Chilenia , Cuyania , and Chaitenia , which now form much of Chile and Patagonia . These collisions were associated with volcanic activity and plutons , but by
15120-442: Was mostly a passive margin, hosting extensive marine deposits in areas such as northwest Africa and Tibet . The eastern margin, though warmer than the west, was equally active. Numerous mountain building events and granite and kimberlite intrusions affected areas equivalent to modern day eastern Australia , Tasmania , and Antarctica. Several island microcontinents (which would later coalesce into modern day Asia) stretched over
15246-469: Was named after Devon by Roderick Murchison and Adam Sedgwick in the 1840s and is the only British county whose name is used worldwide as the basis for a geological time period. Devon's second major rock system is the Culm Measures, a geological formation of the Carboniferous period that occurs principally in Devon and Cornwall. The measures are so called either from the occasional presence of
15372-438: Was northwest of Gondwana, and corresponds to much of modern-day North America and Europe . Various smaller continents, microcontinents , and terranes were present east of Laurussia and north of Gondwana, corresponding to parts of Europe and Asia. The Devonian Period was a time of great tectonic activity, as the major continents of Laurussia and Gondwana drew closer together. Sea levels were high worldwide, and much of
15498-519: Was over a long period incorporated into the kingdom of Wessex and the jurisdiction of the bishop of Wessex. Saint Petroc is said to have passed through Devon, where ancient dedications to him are even more numerous than in Cornwall: a probable seventeen (plus Timberscombe just over the border in Somerset), compared to Cornwall's five. The position of churches bearing his name, including one within
15624-413: Was over £26 billion, larger than either Manchester, or Edinburgh. A 2021 report states that "health, retail and tourism account for 43.1% of employment. Agriculture, education, manufacturing, construction and real estate employment are also over-represented in Devon compared with nationally". Devonian The Devonian ( / d ə ˈ v oʊ n i . ən , d ɛ -/ də- VOH -nee-ən, deh- )
15750-577: Was the newest addition to the Asian microcontinents, it was not the first. North China and the Tarim Block (now northwesternmost China) were located westward and continued to drift northwards, powering over older oceanic crust in the process. Further west was a small ocean (the Turkestan Ocean), followed by the larger microcontinents of Kazakhstania , Siberia , and Amuria . Kazakhstania was
15876-546: Was very similar to that found in Cornish 'tre-' settlements, however these are generally described with the local placename -(a)cott , from the Old English for homestead, cf. cottage . Saxon endings in -worthy (from Anglo-Saxon worthig ) indicate larger settlements. Several 'Bere's indicate Anglo-Saxon wood groves, as 'leighs' indicate clearings. Devon has a variety of festivals and traditional practices, including
