Dinosaurs
For more than 150 million years, life on Earth was dominated by giant reptiles. Such as dinosaurs on land, winged pterosaurs in the sky and a range of sea monsters in the ocean. Find out about what they looked like, when and when they lived and what they ate.
Dinosaurs lived in the Mesozoic
Era, which lasted from 252 to
65 mya. This era is further
divided into the Triassic,
Jurassic and Cretaceous periods.
Dinosaurs died out at the end of
the Cretaceous period, around
65 mya. The earliest hominids
(the first members of the human
family) appeared around 4.4 mya.
Jurassic giants
Dinosaurs continued to evolve in the Jurassic and became the dominant life forms on land. Some grew to huge sizes, such as the theropod Archaeopteryx, took to the air.
Primates emerge
The era after the Mesozoic is called the Cenozoic era. It contains the Palaeogene period, in which primates, the mammalian ancestors of humans first appeared.
