Elosuchus is an extinct genus of neosuchian crocodyliform that lived during the Middle Cretaceous of what is now Africa (Niger, Morocco and Algeria).
Elosuchus had an elongated snout like a gharial and was probably a fully aquatic animal. The type species, E. cherifiensis from Algeria and Morocco, was originally described as a species of Thoracosaurus by Lavocat,[2] but was recognized as a genus separate from Thoracosaurus by de Broin in 2002. Elosuchus felixi, described from the Echkar Formation of Niger, was renamed Fortignathus in 2016 and is either a dyrosaurid relative or a non-hyposaurine dyrosaurid.[3][4]
de Broin (2002) created the family Elosuchidae to contain Elosuchus and the genus Stolokrosuchus from Niger.[3] However, recent phylogenetic analyses usually find Stolokrosuchus to be one of the basalmost neosuchian, only distantly related to Elosuchus.[5][6][7][8] Some analyses find a monophyletic Pholidosauridae that includes Elosuchus,[7] while other analyses find Elosuchus to nest with taxa like Sarcosuchus in a clade as a sister-taxon to the node Dyrosauridae+Pholidosauridae.[6][8]
