Gavialosuchusest un genre éteint de crocodiliens de la sous-famille des Tomistominae (famille des Gavialidae) qui vivaient au début du Miocène en Europe. Le genre Gavialosuchus a été créé en 1885 par les paléontologues autrichiens (1845-1920) et (1856-1923). L'espèce type, Gavialosuchus eggenburgensis, est connue du Miocène ancien autrichien. Albert C. Myrick Jr. (2001) a proposé de synonymiser Gavialosuchus americanus avec Thecachampsa antiqua. (2007) ont cependant préconisé de transférer à la fois G. americanus et G.
TomistomaTomistoma is a genus of gavialid crocodilians. They are noted for their long narrow snouts used to catch fish, similar to the gharial. Tomistoma contains one extant (living) member, the false gharial (Tomistoma schlegelii), as well as potentially several extinct species: T. cairense, T. lusitanicum T. coppensi, and T. dowsoni. However, these species may need to be reclassified to different genera as studies have shown them to be paraphyletic, for example: previously assigned species T.
PenghusuchusPenghusuchus is an extinct genus of gavialid crocodylian. It is known from a skeleton found in Middle to Upper Miocene rocks of Penghu Island, off Taiwan. The taxon was described in 2009 by Shan and colleagues; the type species is P. pani. It may be related to two other fossil Asian gavialids: Toyotamaphimeia machikanensis of Japan and Hanyusuchus sinensis of South China. It was a medium-sized gavialid with an estimated total length of . On 25 March 2006, on the coast of Neian, Shiyu, Penghu Islands, an excavator driver Mr.
HarpacochampsaHarpacochampsa is a poorly known Early Miocene crocodilian from the Bullock Creek lagerstätte of the Northern Territory, Australia. The current specimen consists of a partial skull and fragments of a long, slender snout reminiscent of that of a false gharial, demonstrating that it was a piscivore in life. It was originally tentatively placed within a group of Australian crocodilians now known as the Mekosuchinae, although this has been frequently disputed, with other authors instead suggesting it may have been a more basal crocodyloid or a type of gavialid.
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.
GavialidaeLes Gavialidae sont une famille de crocodiliens. Elle a été nommée par le médecin-militaire Andrew Adams (1827-1882), zoologiste britannique en 1854. Cette famille ne comporte qu'une seule espèce actuelle : Gavialis gangeticus, le gavial du Gange. Autrefois classé dans le même genre, le faux-gavial de Malaisie (ou gavial de Schlegel) fut ensuite inclus dans les Crocodylidae sous le nom de Tomistoma schlegelii. Des doutes persistent quant à sa position systématique (cf.
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.

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.
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.
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.
