One of the most diverse groups of mollusk Cephalopods to exist in the Paleozoic Era, fossils of more than 2, extinct species have been found till now. Popular examples of such organisms that existed around - million years ago are the Discitoceras, Rayonnoceras, Endoceras, Cameroceras, etc. McAlester, A. Lee (Arcie Lee) Overview.

Nucinella owenensis is a species of small, monomyarian, nuculoid bivalve. It was first found at a depth of 3, metres (11, ft) in the Arabian Sea. It is suspected of benefiting from chemosymbiosis with sulphur-oxidizing bacteria. ReferencesFamily: Nucinellidae. average durations of genera in the twogroups (1, 13).

The earliest Permian faunal successions of central Patagonia show compositional changes that probably reflected the environmental warming at the end of the Gondwana glaciations. Bivalves of Asselian to probably Early Tastubian age are described. A new genus,Sueroa, is proposed to reunite a previously known species and a new species,Sueroa andreisi n. by: 9.

Type Species of Paleozoic Nuculoid Bivalve genera,Memoir,2 tables and 36 plates. Paperback – January 1, Author: McAlester. A major obstacle to phylogenetic and systematic study of the Class Bivalvia is inadequate knowledge of hundreds of obscure and poorly defined Paleozoic genera.
This study provides redescriptions and modern illustrations of the type species for all Paleozoic nuculoid bivalve genera, which make up about 10 percent of the generic names proposed for Paleozoic bivalves.

The type species of the early Paleozoic nuculoid pelecypod genus Tancrediopsis Beushausen,is shown to be Ctenodonta contracta Salter,from Middle Ordovician rocks of File Size: 8MB. The new nuculid bivalve Trigonucula (Gonionucula) aciloides new subgenus and species from the upper Triassic Nayband Formation of Central Iran is described.
Gonionucula differs from Trigonucula s.s. by the presence of oblique ribs, which either deviate from a concentric pattern at the anterior shell part, or, as in the newly described type species, consist of a complex pattern of chevron-like Cited by: 4.

Bivalves are very ancient and successful conchiferan mollusks (both in terms of species number and geographical distribution). Despite their importance in marine biota, their deep phylogenetic relationships were scarcely investigated from a molecular perspective, whereas much valuable work has been done on taxonomy, as well as phylogeny, of lower by:
