Not really a lizard, nor a dinosaur: the last surviving species of its kind, the tuatara still exists today and can be found only in New Zealand. Tuatara lived alongside some of the first dinosaurs and separated from other reptiles 200 million years ago in the Upper Triassic period.

Will humans go extinct?

Humanity has a 95% probability of being extinct in 7,800,000 years, according to J. Richard Gott’s formulation of the controversial Doomsday argument, which argues that we have probably already lived through half the duration of human history.

What was before dinosaurs?

The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
