Description and taxonomy

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] The largest known skull indicates a body length of up to 7.7 metres (25 ft 3 in).^[1]

Phylogeny

Restoration of E. cherifiensis

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]
