Sunosuchus

Sunosuchus is an extinct genus of goniopholidid mesoeucrocodylian. Fossils are known from China, Kyrgyzstan, and Thailand and are Jurassic in age, although some may be Early Cretaceous. Four species are currently assigned to the genus: the type species S. miaoi and the species S. junggarensis, S. shartegensis, and S. shunanensis. All species are from China. Goniopholis phuwiangensis, also from Thailand, was reassigned to Sunosuchus by Andrade et al. (2011). The material from Kyrgyzstan has not been assigned to any species.

==Description== Sunosuchus has a long, narrow snout and a small skull table. Several characters help diagnose Sunosuchus and distinguish it from other taxa. For example, there are wide pits on the back of the frontal bone. The frontal bone also has a distinctive ridge along part of its midline. The lower jaw has a long symphysis where the two halves come together. This symphysis is formed mostly from the mandibles, but also partially by the splenials. Unlike other goniopholidids, the squamosal bone (which is found near the back of the skull) is narrow.
