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.
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.
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).
EothoracosaurusEothoracosaurus is an extinct monospecific genus of eusuchian crocodylomorphs found in Eastern United States which existed during the Late Cretaceous period. Eothoracosaurus is considered to belong to an informally named clade called the "thoracosaurs", named after the closely related Thoracosaurus. Thoracosaurs in general were traditionally thought to be related to the modern false gharial, largely because the nasal bones contact the premaxillae, but phylogenetic work starting in the 1990s instead supported affinities within gavialoid exclusive of such forms.
AlligatoroideaLes Alligatoroidea sont une super-famille de reptiles apparue à la fin du Crétacé et contenant la famille des Alligatoridae. Cladistiquement, ils sont définis comme comprenant Alligator mississippiensis (Alligator américain) et tous les crocodiliens qui lui sont plus apparentés qu'à Crocodylus niloticus (Crocodile du Nil). Leurs groupe frère est celui des Crocodyloidea. le clade Globidonta comprend: la famille Alligatoridae: †Brachychampsa, Gilmore 1911 †Stangerochampsa, Wu et al.
