LEEDS, England, April 25 (UPI) -- Like the exodus of early humans out of Africa, dinosaurs made a break from Europe during the Early Cretaceous Period.
Researchers came to the realization after mapping the movement of dinosaur families through the Mesozoic Era, which lasted about 180 million years and included the Triassic, Jurassic, and Cretaceous periods. It's the first time scientists have used "network theory" to visualize dinosaur migrations.
