The dinosaurs that comingled with our ancient ancestors were modern birds—the closest natural relatives to the extinct dinosaurs—which means that we live with dinosaurs too. Dinosaurs were the dominant species for nearly 165 million years, during a period known as the Mesozoic Era.
What lived in the Mesozoic Era?
The dominant land animals were reptiles. The first dinosaurs, marine reptiles, lizards, and tortoises appeared. Mammals appeared during the Triassic, but they remained insignificant until their competitors, the dinosaurs, became extinct at the end of the Cretaceous. Crocodiles were abundant.
Can humans live in Mesozoic Era?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
