 RIO DE JANEIRO, Brazil (AP) - A dinosaur claw fossil found in Brazil reinforces the theory of an evolutionary link between dinosaurs and birds, a new study says. Brazilian scientists dubbed the dinosaur the dino-bird, which they said was found in Minas Gerais state, about 370 miles northwest of Rio.
Ismar de Souza Carvalho, who co-authored the study, said Thursday that it likely belonged to an unknown group of dinosaurs who walked the Earth some 70 million years ago.
"The anatomic structure of this claw shows, quite possibly, the link between carnivore dinosaurs and birds that exist today," said Carvalho, a member of the Paleontological Investigation Center at Minas Gerais state university.
