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.
CrocodiliaCrocodilia (parfois orthographié Crocodylia et francisé en crocodiliens) est un ordre de vertébrés tétrapodes aquatiques ovipares et carnivores qui vivent dans les zones tropicales et subtropicales de la planète. Ils sont apparus sous leur forme actuelle il y a au moins , c'est-à-dire vers le milieu du Jurassique. Les conceptions modernes situent l'origine des crocodiliens parmi un sous-groupe d'archosauriens terrestres du Trias ancien, il y a environ .
GavialisGavialis est un genre de crocodiliens de la famille des Gavialidae. Ce genre ne comporte qu'une seule espèce actuelle : Gavialis gangeticus, le gavial du Gange. Gavialis gangeticus se rencontre en Asie du Sud. Selon : Gavialis gangeticus (Gmelin, 1789) ou Gavial du Gange et les espèces fossiles : †Gavialis curvirostris Lydekker, 1886 †Gavialis breviceps Pilgrim, 1912 †Gavialis bengawanicus Dubois, 1908 †Gavialis lewisi Lull, 1944 Oppel, 1811 : Die Ordnungen, Familien und Gattungen der Reptilien, als Prodrom einer Naturgeschichte derselben.
Gavial du GangeGavialis gangeticus, le Gavial du Gange, est une espèce de crocodiliens de la famille des Gavialidae. C'est la seule espèce actuelle du genre Gavialis. thumb|left|Gavial du Gange Sa longueur peut atteindre plus de six mètres, soit autant que le crocodile du Nil et le crocodile marin. Il est reconnaissable à ses mâchoires particulièrement étroites et allongées. Chez les mâles de plus de quatre mètres, la longueur de la protubérance spongieuse sous le museau peut atteindre jusqu'à six fois sa largeur.
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.
IkanogavialisIkanogavialis est un genre de crocodiliens de la famille des Gavialidae, aujourd'hui disparu. Ses fossiles ont été retrouvés dans la formation d'Urumaco au Venezuela, dans une strate datant de la fin du Miocène, plutôt que du Pliocène comme on l'a pensé dans un premier temps. L'espèce type du genre Ikanogavialis est I. gameroi. Cette espèce est nommée en 1970 à partir de fossiles issus de la formation d'Urumaco.
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.
CrocodyloideaCrocodyloidea is one of three superfamilies of crocodilians, the other two being Alligatoroidea and Gavialoidea, and it includes the crocodiles. Crocodyloidea may also include the extinct Mekosuchinae, native to Australasia from the Eocene to the Holocene, although this is disputed. Cladistically, it is defined as Crocodylus niloticus (the Nile crocodile) and all crocodylians more closely related to C. niloticus than to either Alligator mississippiensis (the American alligator) or Gavialis gangeticus (the gharial).
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.
