The scientific tourist #214 — Postosuchus kirkpatricki

Another fine specimen from the Petrified Forest National Park visitor’s center in Arizona:

Postosuchus kirkpatricki

Postosuchus was another odd creature in the Triassic that looked much like a dinosaur, but wasn’t — it was an archosaur, to be specific, a rauisuchian (close relative to the crocodiles).

During the late Triassic (228 – 202 million years ago), Postosuchus was the apex predator — and one of the largest carnivorous reptiles around. Just think of him as a large (up to 4 meters / 13 feet long and weighing up to 300 kg / 660 lb), fast, occasionally bipedal, armored crocodile — and you’re most of the way there.
