There were no ice caps. Except for coastal areas, much of the land was indeed hot and dry. There were frequent violent monsoons.
When did the dinosaurs disappear from the Earth?
Dinosaurs mysteriously disappeared at the end of the Cretaceous Period, around 65 million years ago.
When did dinosaurs live in a single supercontinent?
At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea.
How did the dinosaurs survive on the Earth?
Most dinosaurs were herbivores, or plant-eaters, but some were carnivorous and hunted or scavenged other dinosaurs in order to survive. At the time the dinosaurs arose, all of the Earth’s continents were connected together in one land mass, now known as Pangaea, and surrounded by one enormous ocean.
