Susisuchus
''Susisuchus'' is an extinct genus of neosuchian mesoeucrocodylian crocodyliform from the Early Cretaceous of Brazil. Fossils have been found from the Nova Olinda Member of the Aptian-age Crato Formation in the Araripe and Lima Campos Basins of northeastern Brazil. Named in 2003, ''Susisuchus'' is the sole member of the family Susisuchidae, and is closely related to the clade Eusuchia, which includes living crocodilians. The type species is ''S. anatoceps'', known from a single partial articulated skeleton that preserves some soft tissue. A second species, ''S. jaguaribensis'', was named in 2009 from fragmentary remains.
==Species==
The genus ''Susisuchus'' was first erected with the description of the type species ''S. anatoceps'' in 2003. ''S. anatoceps'' was found in the Aptian-age Crato Formation in the Araripe Basin, and was the first crocodyliform to be described from the formation. The holotype skeleton is the most complete known specimen of ''Susisuchus'', including most of the bones except for those of the hindlimbs, and even traces of soft tissue. The specimen is thought to have been a desiccated carcass before it was buried and later fossilized. A second species, ''S. jaguaribensis'', was named in 2009 from the Lima Campos Basin about from where the skeleton of ''S. anatoceps'' was uncovered.
A new crocodyliform specimen from the Crato Formation was described in 2009. It can be distinguished from the two other crocodyliforms known from the formation, ''Araripesuchus'' and the trematochampsid ''Caririsuchus'', on the basis of characteristics of the fibula and proportions of the femur and tibia. Since the limb elements differ from all other known crocodyliforms from the Araripe Basin, the specimen was tentatively classified as cf. ''Susisuchus'' sp.
