RIO DE JANEIRO, BRAZIL - Ypupiara lopai is the latest Brazilian dinosaur species, it belongs to the dromaeosauridae family whose best known member is the velociraptor. It lived sometime between 72 and 66 million years ago, just before the fatal asteroid hit the Earth and extinguished all dinosaurs.
The dromaeosauridae are a subgroup of the theropods - dinosaurs that walk on two legs and are typically carnivorous, such as the tyrannosaurus.
Yet the Ypupiara is closer to today's birds than to the T-Rex. "It's as if it were the birds' uncle, and the tyrannosaurs were the great-grandparents," explains . . .
