The Treatise on Invertebrate Paleontology (or TIP ) published by the Geological Society of America and the University of Kansas Press, is a definitive multi-authored work of some 50 volumes , written by more than 300 paleontologists , and covering every phylum, class, order, family , and genus of fossil and extant (still living) invertebrate animals. The prehistoric invertebrates are described as to their taxonomy , morphology , paleoecology , stratigraphic and paleogeographic range. However, taxa with no fossil record whatsoever have just a very brief listing.
22-502: See text The Plectoceratidae is a family of tarphycerids in the suborder Barrandeocerina established as a place for the genus Plectoceras ; defined (Sweet 1964) simply as coiled, costate barrandeocerids with subcentral adult siphuncle . According to Sweet, in the original Treatise Part K, the Plectoceratidae included only Plectoceras . Flower, 1984, however added six other genera, two new and four removed from both
44-453: A committee and a chief editor for each volume, with yet other authors and researchers assigned particular sections. Museum collections that had not been previously described were studied; and sometimes new major taxonomic families—and even orders—had to be described. More attention was given to transitional fossils and evolutionary radiation —eventually producing a much-more complete encyclopedia of invertebrate paleontology. But even in
66-472: A result, each publication became a comprehensive compilation of everything known at that time for each group. Examples of this stage of the project are Part G. Bryozoa , by Ray S. Bassler (the first volume, published in 1953), and Part P. Arthropoda Part 2, the Chelicerata by Alexander Petrunkevitch (1955/1956). Around 1959 or 1960, as more and larger invertebrate groups were being addressed,
88-665: Is classified according to a cladistic arrangement, with three subphyla and a large number of classes replacing the original two classes of Articulata and Inarticulata. All these discoveries led to revisions and additional volumes. Even those taxa already covered were expanded: Books such as those regarding the Cnidaria (vol. F), the Brachiopoda (vol. H) and the Trilobita (vol. O) each went from one modest publication to three large volumes. And yet another volume regarding
110-426: Is implied. Either that or it was able to retreat deep into its portable lair. As for whatever arms or tentacles they may have had, no indication has been found. They probably went through two stages, first a younger more active and swimming stage with simple coiled shells, followed by a less active, bottom-dwelling stage with shells that diverge during which they mated and produced, probably a single litter of young, like
132-542: Is the thin-walled connecting rings in their siphuncles. A 1988 classification divides the Tarphycerida into suborders Tarphycerina and Barrandeocerina, which were previously defined as separate orders. Tarphycerids are more closely related to the diverse Oncocerida , through the ancestral Bassleroceratidae in the Lower Ordovician, than to the other nautiloid orders. The Oncocerida, in turn, gave rise to
154-648: The Barrandeoceratidae and Apsidoceratidae . Genera according to Flower, 1984 are: Plectoceras Hyatt -type genus Avilionella -removed from Barradeoceratidae Bodeiceras , Flower 1984. added Chidleyenoceras - removed from the Apsidoceratidae Metaplectoceras , Flower (?synonym for Plectoceras) Laureloceras Flower 1957, removed from Barrandeoceratidae Laurelplecoceras Flower 1984 -added According to Flower, 1984, Plectoceras , and therefore
176-542: The Nautilida which include the recent Nautilus and Allonautilus . This puts the Tarphycerida in the broad group that includes the nautilids. It makes them also separate from the groups that include the Discosorida , Actinocerida , Endocerida , and Orthocerida , and from the superficially similar Ammonoidea . The tarphycerid animal must have been rather elongated, like squid, although no close relationship
198-483: The Treatise are revised. Raymond C. Moore , the project's founder and first editor , originally envisioned this Treatise in invertebrate paleontology as comprising just three large volumes, and totaling only three thousand pages. The project began with work on a few, mostly slim volumes in which a single senior specialist in a distinct field of invertebrate paleozoology would summarize one particular group. As
220-675: The Plectoceratidae, is derived from the Tarphyceratid genus Campbelloceras while Barrandeoceras , and therefore the Barrandeoceratidae, is derived from Centrotarphyceras . The inclusion of Laureloceras expands the range of the Plectoceratidae into the Middle Silurian from the Upper Ordovician when it had been with only Plectoceras Tarphycerida The Tarphycerida were the first of
242-592: The ancestral Bassleroceratidae. The Estonioceratidae, Tarphyceratidae, and Trocholitidae are primitive forms characterized by siphuncles with thick-walled connecting rings. The Ophidioceratidae are derived offshoots. The barrandeoceratid and plectoceratid families were once combined in the Barrandeocerida, determined to be invalid due to having multiple ancestors in the Tarphyceriatidae and therefore abandoned. The common characteristic of these forms

The tarphyceratids comprise the Tarphycerida of the Treatise on Invertebrate Paleontology Part K to which Flower added

Kaesler at The Paleontological Institute at the University of Kansas in Lawrence, Kansas. The current editor is Bruce S. Lieberman . All previously published volumes are now available open access by clicking here . From the beginning, the character of the Treatise volumes has followed and further developed
308-562: The coiled cephalopods , found in marine sediments from the Lower Ordovician (middle and upper Canad ) to the Middle Devonian . Some, such as Aphetoceras and Estonioceras , are loosely coiled and gyroconic; others, such as Campbelloceras , Tarphyceras , and Trocholites , are tightly coiled, but evolute with all whorls showing. The body chamber of tarphycerids is typically long and tubular, as much as half

Furthermore, each Treatise article includes (j) the date, authorship, and scientific history of the taxa . Finally, there is (k) a comprehensive bibliography and list of references. Not only that, but the more recent volumes and revisions also include (l) new fossil and phylogenetic discoveries, (m) advances in numerical and cladistic methods, (n) analysis of

This is followed by (f) a listing and technical description of every known genus, along with (g) geographic distribution (usually by continent only, but occasionally by country) and (h) stratigraphic range. Next come (i) one or two representative species illustrated by line drawings (in
374-401: The incompleteness of the then-current state of affairs became apparent. So several senior editors of the Treatise started major research programs to fill in the evident gaps. Consequently, the succeeding volumes, while still maintaining the original format, began to change from being a set of single-authored compilations into being major research projects in their own right. Newer volumes had

Younger, wholly coiled forms were probably more active, nektobenthic, certainly more maneuverable. The Tarphycerida comprise three phylogenetically related groups of families. They are: the tarphyceratid group consisting of the Estonioceratidae , Tarphyceratidae , Trocholitidae , and Ophidioceratidae ;

The Tarphycerida evolved from the elongated, compressed, exogastric Bassleroceratidae , probably Bassleroceras , around the end of the Gasconadian through forms like Aphetoceras . Close coiling developed rather quickly, and both gyroconic and evolute forms are found in the early middle Canadian . Tarphycerids tend to uncoil in
440-442: The modern but unrelated coleoids . Treatise on Invertebrate Paleontology Publication of the decades-long Treatise on Invertebrate Paleontology is a work-in-progress; and therefore it is not yet complete: For example, there is no volume yet published regarding the post- Paleozoic era caenogastropods (a molluscan group including the whelk and periwinkle ). Furthermore, every so often, previously published volumes of

Following their lead, the Treatise includes in a typical article (a) a description of the basic anatomy of the modern members of each invertebrate group, (b) distinctive features of the fossils, (c) a comprehensive illustrated glossary of terms, (d) a short discussion of the evolutionary history of
