A Living Fossil

The tuatara is one of the rarest creatures on earth. Tuataras are the only living members of an ancient group of reptiles called rhynchocephalians, or “beak-heads.” They are sometimes referred to as living fossils, because they have lived on Earth ever since the time of the dinosaurs. Tuataras are only found on a few small islands off the coast of New Zealand. They look fierce, but are actually very sleepy and slow-moving. This living fossil is so lazy, in fact, that it would rather move into the burrow of a bird called the sooty shearwater, than dig its own underground home.

Vocabulary
