The Cretaceous period.
The earliest period that dinosaurs existed was the Triassic period, some 225 million years ago. These were not the huge dinosaurs of the later period. Most dinosaurs of that age were small creatures that ate meat and walked on hind legs. Shaaron
Early Dinosaurs that evolved from the Jurrasic times.
Grass only evolved late in the Cretaceous period so only the dinosaurs near the end of the age of dinosaurs would have had grass available. Remains of early grasses have been found in dinosaur coprolites of this period.
Jurassic Period. That's pretty much it. Its the middle of the Age of Dinosaurs.
The "Age of Dinosaurs" came to an end with the extinction event at the end of the Cretaceous.
The ice age began at the end of the Jurassic period, a theory of why the dinosaurs became extinct. <33
"Age of the dinosaurs" is a common nickname for the Mesozoic Era because it was a period when dinosaurs dominated the Earth.
The Triassic Period is a geological time period that occurred from about 251 to 201 million years ago. It followed the Permian Period and preceded the Jurassic Period in the Mesozoic Era. The Triassic Period saw the diversification of early reptiles and the rise of dinosaurs.
No. Mammoths are from the ice age not the Mesozoic era (dinosaur age).
