Giant Salamander-Like Predator Dominated Prehistoric Swamps

Gaiasia jennyae, a top predator with a unique skull, lived 40 million years before dinosaurs in the icy swamps of ancient Namibia.

  • Gaiasia jennyae had a two-foot-long skull and was larger than a person.
  • It used its toilet seat-shaped head and interlocking fangs to ambush prey.
  • The species thrived in cold, swampy environments near the 60th parallel south.
  • Its discovery challenges previous beliefs about early tetrapod distribution.
  • Named for the Gai-As Formation in Namibia and paleontologist Jenny Clack.
