While the origin of flowering plants may go back as far as the Triassic Period, we don't see much evidence of them in the fossil record at the start of the Cretaceous. However, by the end of the ...

The Mesozoic Era extinctions formed the world as we know it today. Read about what caused them and which animals survived.

The mid-Cretaceous period, spanning roughly 100 to 90 million years ago, was a time of significant evolutionary transformation. Flowering plants were rapidly diversifying, dinosaurs still dominated ...
