Otocoelus Dissorophus post crania
Dissorophus

Dissorophus multicinctus (Cope 1895; Late Carboniferous, 280 mya) also had a large head and short trunk, but more dermal and subdermal ossifications. This terrestrial basal tetrapod was originally considered a "bratrachian armadillo" with its double-layer armor. Distinct from most basal tetrapods, except frogs, the limbs were quite large.
