Yet another discovery – a dinosaur claw fossil. But, this time the finding reinforces the evolutionary link theory existing between birds and dinosaurs. A new study claims this. About 370 miles northwest of Rio, the fossil part was found in Minas Gerais state. The Brazilian scientists called the dinosaur the dino-bird, in accordance with the finding.
It has been predicted that this body-part belongs to a group of dinosaurs, still unknown to us. The dinosaur is thought to have romped the Earth about 70 million years ago. The study is co-authored by Ismar de Souza Carvalho.
Carvalho, a member of the Paleontological Investigation Center at Minas Gerais state university said,
The anatomic structure of this claw shows, quite possibly, the link between carnivore dinosaurs and birds that exist today.
But one expert, Thomas R. Holtz, Jr., a vertebrate paleontologist at the University of Maryland argues that a claw fragment can not reveal the existence of a dinosaur, which was previously unknown. He commented,
If this claw was all that was found, then it would be rather extravagant to create an elaborate theory based upon it. This claw doesn’t add particularly much to our knowledge of the origins of birds, but it does show that raptor dinosaurs were present in Brazil toward the end of the age of dinosaurs.
