Pleuroceras is a genus of ammonite from the lower Jurassic, upper Pliensbachian. [1]
Pleuroceras has a planulate shell with a quadrate whorl section, bearing strong radial ribs ending in ventro-lateral tubercles. The venter is tabulate with a strong serrated keel.
Species of this genus were fast-moving nektonic carnivores. Its fossils have been found in Canada and Europe (Bulgaria, France, Germany, Hungary, Italy, Montenegro, Romania, Serbia, Spain and United Kingdom). [2]
Aegoceras is an evolutionary wound ammonite, with wide spaced ribs, from the Early Jurassic (England) included in the Liparoceratidae and superfamily Eoderoceratidae. Related genera are Leparoceras and Beaniceras.
Arcestes is a genus of extinct ceratitid ammonites found in Triassic-aged marine strata.
Pleurocera is a genus of freshwater snails with an operculum, aquatic gastropod mollusks in the family Pleuroceridae.
Bradfordia is a moderately involute to involute genus included in the ammonoid cephalopod family Oppeliidae, coiled so that the outer whorl encloses most, or much, of the previous, but with a small umbilicus exposing inner whorls. The shell is compressed, whorl height much greater than width, extending well out from the contact with the adjacent inner whorl. Outer flanks are finely ribbed and the rounded venter is smooth.
Diplesioceras is an extinct genus from a well-known class of fossil cephalopods, the ammonites. It lived during the Bajocian.
Eudmetoceras is an extinct genus from a well-known class of fossil cephalopods, the ammonites. It lived during the Jurassic Period, which lasted from 171.6 to 168.4 million years ago.
Euaptetoceras is an evolute hildoceratoid ammonite from the lower Middle Jurassic, included in the family Hammatoceratidae and the subfamility Hammatoceratinae. The genus may be a junior synonym for Eudmetoceras of Buckman, 1920.
Ermoceras is a genus of ammonite belonging to the Thomboceratidae family of the Middle Jurassic found in deposites of central Arabia, Sinai, and Algeria with strong primary and secondary ribs and a single row of lateral tubercles; described as having a deep ventral groove
Epistrenoceras is an extinct genus from a well-known class of fossil cephalopods, the ammonites. It lived during the Bajocian to the Bathonian.
Eocephalites is an extinct genus from a well-known class of fossil cephalopods, the ammonites. It lived during the Bajocian.
Emileia is an extinct genus from a well-known class of fossil cephalopods, the ammonites, that lived during the early part of the Bajocian.
Sthenarosaurus is an extinct genus of rhomaleosaurid pliosauroid discovered in the Toarcian-aged 'Main Alum Shale' in Whitby, England. The type species, S. dawkinsi, was named and described in 1909. The type specimen is MMUM LL 8023, a set of postcrania discovered in Whitby. Other indeterminate specimens are known, including a pectoral girdle described in 1911.
Arctosomus is an extinct genus of prehistoric bony fish that lived during the Early Triassic epoch.
Promicroceras is an extinct ammonite genus from the upper Sinemurian of Europe, named by Leonard Spath in 1925. Promicroceras is included in the family Eoderoceratidae, which is part of the ammonitid superfamily Eoderoceratoidea.
Tarasiiformes is an extinct order of prehistoric ray-finned fish.
Lopha is a genus of marine bivalve molluscs in the family Ostreidae.
Titanites is an extinct ammonite cephalopod genus within the family Dorsoplanitidae, that lived during the late Tithonian of the Late Jurassic.
Sowerbyceras is a genus of ammonoid cephalopods belonging to the family Phylloceratidae. These nektonic carnivores lived during the Jurassic period, from Oxfordian to Kimmeridgian age.
Pleuroceras spinatum is a species of ammonite from the lower Jurassic, upper Pliensbachian period. Species of this genus were fast-moving nektonic carnivore.
Harpoceras is an extinct genus of ammonite belonging to the family Hildoceratidae. These cephalopods existed in the Jurassic period, during the Toarcian age from the Falciferum zone to the Commune subzone of the Bifrons zone. They were fast-moving nektonic carnivores.
