Pachycephalosaurus carried one of the most extraordinary skulls in the fossil record. Its thick dome may have served in combat, display, recognition, or several purposes at once—and its changing shape reveals how much paleontology still has to learn.
Explore the Jurassic world of Pangaea, colossal sauropods, ocean predators, pterosaurs, Archaeopteryx, and the small mammals that quietly prepared for the future.
Hatzegopteryx was one of the largest flying animals ever known. Its massive skull, reinforced bones, and unusual anatomy reveal how this Transylvanian pterosaur lived in the island world of the Late Cretaceous.
Carnotaurus was a uniquely specialized abelisaurid: a swift, horned predator with a deep skull, powerful hind limbs, vestigial arms, and exceptionally preserved skin impressions. Its anatomy reveals how isolation shaped an unusual predatory strategy in Patagonia.
Parasaurolophus was a Late Cretaceous herbivore whose extraordinary hollow crest may have helped it communicate across floodplains, warn its herd, and identify members of its own kind.
With towering back plates, a low-slung body, and a weaponized tail, Stegosaurus was far more than an easy meal. Explore its Jurassic world, defensive anatomy, discovery, and enduring scientific mysteries.
