Psephoderma had a long tail, up to about 80 cm (31 inches), covered in bony scutes.1
Its shell was split into two pieces: one over the ribs and another over the pelvis.1
The largest known Psephoderma fossil is 180 cm (5.9 feet) long.3
Its skull had a narrow, straight snout with grooves that led to the nostrils.1
Psephoderma had no teeth at the front of its mouth, only four large crushing teeth on each side of the palate.1
