Protosuchia

Protosuchians are early crocodilians that were small in size (~1 meter in length) and terrestrial.

Protosuchian genera
Recent phylogenetic analyses have not supported Protosuchia as a natural group. However, two studies found a clade of Late Triassic-Early Jurassic animals:


 * Orthosuchus
 * Protosuchus
 * Hemiprotosuchus
 * Edentosuchus

Both of these studies also found a clade more closely related to Hsisosuchus and Mesoeucrocodylia consisting of Late Jurassic-Late Cretaceous genera:


 * Zosuchus
 * Sichuanosuchus
 * Shantungosuchus
 * Neuquensuchus

However, other possible protosuchians from the Late Cretaceous of China-Mongolia, the Gobiosuchidae (Gobiosuchus and Zaraasuchus), have been found to either intermediate between these two clades, or members of the or the Sichuanosuchus-clade.
