Dibothrosuchus elaphros (Early Jurassic, Wu and Chatterjee 1993) is known from an incomplete skeleton, lacking hind limbs and distal tail. So we don't know whether this was a biped or quadruped. Derived from a sister to Saltoposuchus and Sphenosuchus, Dibothrosuchus was basal to Simosuchus and all living crocodyliformes.
Distinct from sister taxa, the rostrum was perforated for the lower fang to enter. The lateral temporal fenestra was elaborated with a quadrate with three dorsal heads for a strong articulation with the skull roof. The cervicals and their ribs were quite robust. The proximal carpals were longer than the metacarpals.
