The world then
The continents drift apart. The Atlantic widens, India heads north and a shallow sea splits North America in two. Warm, with some of the highest sea levels and temperatures in the Phanerozoic. Flowering plants spread and reshape the forests. Highest of the Mesozoic by the Late Cretaceous.
Epochs
- Early Cretaceous: 143.1 to 100.5 Ma
- Late Cretaceous: 100.5 to 66 Ma
Key events
- Flowering plants appear and spread
- Tyrannosaurs, horned dinosaurs, duck-billed dinosaurs and armoured dinosaurs diversify
- The longest period of the three, nearly 80 million years
- An asteroid strikes Mexico 66 Ma, ending all non-avian dinosaurs
