Discovering Dinosaurs
Learning Objective
I can name different types of dinosaurs.
Key Concepts
One theory suggests dinosaurs evolved from reptiles called archosaurs, which split into two groups: one leading to crocodiles, the other to dinosaurs.
During the Triassic period, the supercontinent Pangaea began to fragment, and early dinosaurs like the Eoraptor and celophysis emerged.
The Cretaceous Period saw the rise of the Tyrannosaurus Rex, but ended with an asteroid impact that wiped out 75% of Earth's species, though some avian dinosaurs survived and evolved into birds.
