GavialoideaLes Gavialoidea sont l'une des trois super-familles de crocodiliens, les deux autres étant les Alligatoroidea et les Crocodyloidea. Alors qu'on en connaît de nombreuses espèces éteintes, il n'en subsiste plus que le Gavial (Gavialis gangeticus) et, peut-être, le Faux-gavial de Malaisie (Tomistoma schlegelii). Les Gavialoidea contiennent la famille des Gavialidae et plusieurs autres genres primitifs aujourd'hui éteints tels que Thoracosaurus et Eosuchus.
DollosuchoidesDollosuchoides, colloquially known as the Crocodile of Maransart, is an extinct monospecific genus of gavialoid crocodilian, traditionally regarded as a member of the subfamily Tomistominae. Fossils have been found in the Brussel Formation of Maransart, Belgium and date back to the middle Eocene. The holotype, IRScNB 482, was discovered in 1915 and it was prepared during 1926–1927 by M. Hubert, J. Mehschaert and M.
KentisuchusKentisuchus is an extinct genus of gavialoid crocodylian, traditionally regarded as a member of the subfamily Tomistominae. Fossils have been found from England and France that date back to the early Eocene. The genus has also been recorded from Ukraine, but it unclear whether specimens from Ukraine are referable to Kentisuchus. The genus Kentisuchus was erected by Charles Mook in 1955 for the species "Crocodylus" toliapicus, described by Richard Owen, in 1849.
MaroccosuchusMaroccosuchus zennaroi is an extinct gavialoid crocodylian from the Early Eocene of Morocco, traditionally regarded as a member of the subfamily Tomistominae. Below is a cladogram based on morphological studies comparing skeletal features that shows Maroccosuchus as a member of Tomistominae, related to the false gharial: Based on morphological studies of extinct taxa, the tomistomines were long thought to be classified as crocodiles and not closely related to gavialoids.
ParatomistomaParatomistoma (meaning "next to or near Tomistoma") is an extinct monospecific genus of gavialoid crocodylian. It is based on the holotype specimen CGM 42188, a partial posterior skull and lower jaw discovered at Wadi Hitan, Egypt, in Middle Eocene-age rocks of the Gehannam Formation. The skull is unfused but considered morphologically mature. Paratomistoma was named in 2000 by Christopher Brochu and Philip Gingerich; the type species is P. courti in honor of Nicholas Court, who found CGM 42188.
TomistominaeLes tomistominés (Tomistominae) constituent une sous-famille de crocodiliens dont une seule espèce existe encore aujourd'hui, le faux-gavial de Malaisie du genre Tomistoma. Tomistoma Müller, 1846 et les genres fossiles : Dollosuchoides Brochu, 2007 Dollosuchus Owen, 1850 Eotomistoma Young, 1964 Ferganosuchus Efimov, 1982 Gavialosuchus Toula & Kail, 1885 Kentisuchus Mook, 1955 Maroccosuchus Jonet & Wouters, 1977 Megadontosuchus Mook, 1955 Paratomistoma Brochu & Gingerich, 2000 Penghusuchus Shan, Wu, Cheng &
Tomistoma cairenseTomistoma cairense is an extinct species of gavialoid crocodilian from the Lutetian stage of the Eocene era. It lived in North East Africa, especially Egypt. Remains of T. cairense have been found in the Mokattam Formation, in Mokattam, Egypt. Tomistoma cairense did not have a Maxilla process within their lacrimal gland, whereas all extant (living) crocodilians do.
AlligatorLes alligators forment un genre de crocodiliens de la famille des Alligatoridés. Ce terme constitue à la fois un nom vernaculaire et un nom scientifique. Selon : Alligator mississippiensis (Daudin, 1802) — Alligator d'Amérique Alligator sinensis Fauvel, 1879 — Alligator de Chine Espèces fossiles : †Alligator prenasalis (Loomis1, 1904) - datant de l'Oligocène et trouvé dans le Dakota du Sud. Le mot alligator est emprunté à l’anglais, lui-même issu d’une déformation de l'espagnol el lagarto, littéralement « le lézard », selon le nom donné par les conquistadors espagnols à ce reptile qui leur était jusqu’alors inconnu.
EosuchusEosuchus ("dawn crocodile") is an extinct genus of eusuchian crocodylomorph, traditionally regarded as a gavialoid crocodilian. It might have been among the most basal of all gavialoids, lying crownward of all other known members of the superfamily, including earlier putative members such as Thoracosaurus and Eothoracosaurus. Fossils have been found from France as well as eastern North America in Maryland, Virginia, and New Jersey. The strata from which specimens have been found date back to the late Paleocene and early Eocene epochs.
Crocodile de JohnstonCrocodylus johnsoni, le Crocodile de Johnston, est une espèce de crocodiliens de la famille des Crocodylidae. thumb|left|Distribution Cette espèce est endémique du nord de l'Australie. Elle se rencontre dans le Territoire du Nord, dans le nord du Queensland et dans le nord-ouest de l'Australie-Occidentale. Ce petit crocodile d'eau douce possède, comme tous ses congénères, des pattes palmées que prolongent des griffes servant à agripper les rives et à creuser un nid pour déposer ses œufs.
