Eryops ( /ˈɛəri.ɒps/) meaning "drawn-out face" because most of its skull was in front of its eyes (Greek ερυειν, eryein = drawn-out + ωψ, ops = face) is a genus of extinct, semi-aquatic temnospondyl amphibian found primarily in the Lower Permian-aged Admiral Formation (about 295 million years ago) of Archer County, Texas, but fossils are also found in New Mexico and parts of the eastern United States. Eryops also occurs in older Pennsylvanian strata of the Conemaugh Group in West Virginia. Eryops averaged a little over 1.5-2.0 meters (5–6 ft) long, making it one of the largest land animals of its time. It weighed about 90 kilograms (200 lb). It probably had few predators, although it would have likely been preyed upon by Dimetrodon, which was larger and was the apex predator at the time. Several complete skeletons of Eryops have been found in the Lower Permian, but skull bones and teeth are the most common fossils.

In The Land Before Time

Eryops makes its first appearance in the opening narration of The Land Before Time VI: The Secret of Saurus Rock, where a red individual appears climbing on top of a rock in a swamp environment. Another individual appears in the opening narration of The Land Before Time X: The Great Longneck Migration. It appears as a large quadrupedal reptilian creature that behaves much like a crocodile. One is seen trying to catch two dragonflies. More are seen resting on a small island on a swamp.
