Beasts of land and skies and the winner of the longevity award
The descendants of Homeosaurus are alive and well today in New Zealand.
Homeosaurs looked like plump lizards from the outside. But their inner structure was distinctive. The skull was rigid so the snout couldn’t flex the way a lizard’s can. Plus, the teeth worked like self-sharpening scissors to slice through tough-skinned prey.

Homeosaurs were the Ultimate Jurassic Survivors. They came from an old group that first evolved far back in the preceding Period, the Triassic. Today a homeosaur descendant, the Tuatara, still lives along the coast of New Zealand. No other family of Jurassic reptile has lasted so long with such little change.
How did they do it? What’s the secret behind homeosaur survival? We don’t know….yet. What do you think?
