Dinosaurs are a diverse group of reptiles that first appeared between 243 and 233.23 million years ago.

Different Dinosaur communities were seperated by time and geography, the 'Age of the Dinosaur', also known as the Mesozoic Era, consisted of three consecutive geologic time periods.

• + The Triassic Period +

  252 to 201 million years ago

  Liliensternus, Herrerasaurus & Asylosaurus

• + The Jurassic Period +
