An illustration of Early Permian life in Texas. The Temnospondyl
Eryops lunges for the freshwater shark
Orthacanthus. A
Trimerorhachis is seen in the foreground.
Eryops was roughly 5 feet in length.
N.B. The picture shows
Eryops with 5 digits on its hand. We now know that they had only 4 digits on their manus, or forelimb.
