Early Cretaceous Period
The discovery of fossils of Deinonychus in Montana in the 1960’s revealed that dinosaurs were much more bird-like and active than previously believed. Deinonychus, Velociraptor, and other dromaeosaurs (sometimes called ‘raptors’) were closely related to modern birds and fossils indicate that, like modern birds, they had feathers.
