Throughout the Mesozoic era the roles mammals could take on was limited because many of those roles were already filled by dinosaurs. After the extinction event that competition was removed and the mammals could take on new roles.
The current era is the "great age of mammals," the Cenozoic. The Mesozoic was the age of dinosaurs.
Mammals first evolved during the Mesozoic, the age of dinosaurs. After the dinosaurs died out, the Cenozoic began and mammals diversified until they dominated the land. Currently, we still live in the Cenozoic, so, technically, the Cenozoic could be called "the age of mammals."
It is thought that the age of mammals started when the dinosaurs died out 65 million years ago.
No. Mammoths are from the ice age not the Mesozoic era (dinosaur age).
Primitive mammals, with fur, did exist during the age of dinosaurs. It has sometimes been speculated that mammals caused or helped to cause the extinction of the dinosaurs by eating dinosaur eggs.
The modern era that began approximately 65 million years ago with the mass extinction of the dinosaurs is called the Cenozoic era. It is also known as the Age of Mammals, as mammals began to dominate the Earth during this time.
"Age of the dinosaurs" is a common nickname for the Mesozoic Era because it was a period when dinosaurs dominated the Earth.
Between 65.5 and 146 million years ago.
Yes. The first mammals appeared only about ten million years after the first dinosaurs in the Triassic period.
the paleozioc was the age of dinosaurs. the first small mammals first appeared in this time
The age before the dinosaurs, also known as the mesozoic era, was the paleozoic era, which started apprx. 570 million years ago and ended apprx. 245 million years ago
there was no dinosaurs during the ice age
