Cladiscites is an extinct genus of cephalopods in the ammonoid order Ceratitida. These nektonic carnivores [2] lived during the Triassic, from Carnian to Rhaetian age. [1]
Fossils of species within this family have been found in the Triassic of Afghanistan, Hungary, Italy, Oman, Tajikistan, United States [2] and the East Indies.
Arcestes is a genus of extinct ceratitid ammonites found in Triassic-aged marine strata.
Zeuchthiscus is a genus of prehistoric ray finned fish that lived in Australia during the Early Triassic Period. It is believed to have been a nektonic omnivore. Closely related fish had a wide distribution in the northern hemisphere.
Psiloceras is an extinct genus of ammonite. Psiloceras is among the earliest known Jurassic ammonites, and the appearance of the earliest Psiloceras species form the definition for the base of the Jurassic. Unlike most earlier ammonites, which had complex shell shapes and ornamentation, Psiloceras had a smooth shell.
Ptycholepis is an extinct genus of prehistoric ray-finned fish having the head and opercular bones ornamented with ridges of ganoin, minute teeth, and thick scales.
Pessosaurus is an extinct genus of ichthyosaurs which existed during the Middle Triassic period.
Gymnites is a genus of ammonoid cephalopod from the Middle Triassic belonging to the ceratitid family Gymnitidae. These nektonic carnivores lived during the Triassic period, the Anisian age.
Episageceratinae is a subfamily of the Medlicottiidae, a family of prolecanitid ammonites. The Episageceratinae, proposed by Ruzhencev, 1956, is based on the genus Episageceras previously included in the subfamily Medlicottiinae and lived during Late Permian and Early Triassic times. So far only three confirmed genera are included: Episageceras, Latisageceras, and Nodosageceras.
Ampullina is an extinct taxonomic genus of deep-water sea snails, marine gastropod molluscs in the clade Caenogastropoda. These sea snails were epifaunal grazers. They lived from the Middle Triassic period to the Lower Pliocene age.
Lopha is a genus of marine bivalve molluscs in the family Ostreidae.
Neophylloceras is an extinct genus of cephalopod belonging to the Ammonite subclass.
Metoioceras is an extinct genus of cephalopod belonging to the Ammonite subclass which lived during the Cenomanian.
Parapopanoceras is a ceratitid ammonite with a small, smooth, very involute and moderately globose shell that lived during the middle Triassic.
Dagnoceras is a ceratitid ammonite from the Lower Triassic that has a basically evolutute, discoidal shell with an arched venter and ceratitic sutures. The Treatise 1957 includes it in the Meekoceratidae although it has since been placed in the Dinaritidae.
Daxatina is a fossil ammonoid cephalopod included in the trachyceratid family of the order Ceratitida that lived during the middle of the Triassic.
Olenekoceras is an ammonoid cephalopod from the Lower Triassic included in the ceratitid family Sibiritidae, once included in the Noritaceae but now in the Ceratitaceae.
Hedenstroemia is an extinct genus of Early Triassic (Olenekian) cephalopods in the ammonoid order Ceratitida. They were nektonic carnivores.
Ptychites is an extinct genus of cephalopods belonging to the family Ptychitidae. These nektonic carnivores lived during the Triassic period, from Anisian to Ladinian age.
Monophyllites is an extinct cephalopod genus belonging to the family Ussuritidae that lived during the Triassic period, from Anisian to Ladinian age.
Rhacophyllites is an extinct genus of cephalopods belonging to the family Discophyllitidae. These nektonic carnivores lived during the Triassic period, from Carnian to Rhaetian age.
Brotheotrachyceras is a genus of ammonite cephalopod belonging to the order Ceratitida. It was living during the Carnian age of the Late Triassic Epoch.
