Eucritta melanolimnetes (Clack 1998, 2007; Viséan, Early Carboniferous, 340 mya; ~25cm in length) was originally considered a loxomatid amphibian, due to keyhole shaped orbits. Eucritta nests as a basal reptilomorph. Five specimens are known. Another skull is shown below. Eucritta grew isometrically wth greater ossification in larger specimens, including longer ribs. |
