Eryops megacephalus
Eryops megacephalusEryops megacephalus was a robust, apex ambush predator that prowled the lowland swamps and river margins of equatorial Pangaea during the early Permian. Supported by a stout spine and thick, sprawling limbs, it could haul its heavy body onto land but remained tied to water for breeding and hunting. Its massive, flattened skull housed dozens of curved, labyrinthodont teeth designed to clamp down instantly on slippery fish and smaller tetrapods.
