Genus Eosuchus Dollo, 1907
Type species: Eosuchus lerichei Dollo, 1907 .
Species assigned.— Eosuchus lerichei Dollo, 1907 and Eosuchus minor ( Marsh, 1870) .
Definition.—A stem−based group name including the type species, E. lerichei Dollo, 1907 , plus E. minor ( Marsh, 1870) and all gavialoids more closely related to them than to Eogavialis africanus .
Emended diagnosis.—A basal gavialoid that can be differentiated from any other crocodylian by the following combination of characters: an unusually enlarged foramen aereum, dentary alveoli arranged in couplets, evident “quadrate crest” ventrally developed at least on quadrates and pterygoids, nasals reaching and deeply entering between premaxillae, W−shaped basioccipital tuberosity. A further peculiarity could be represented by the presence of an unusual “steplike” widening of the orbital margin of prefrontal.
