The reason for the fowl breath of dinosaurs


The mechanism by which Dinosaurs may have breathed have been found by the biologists and paleontologists at the University of Manchester.

It has been discovered that theropod dinosaurs like Velociraptor has respiratory systems as in present day diving birds. Dinosaurs had many similarities to birds and this similarity has been found to be present in the respiratory system as air sac respiratory system.

Studies were conducted on the fossil remains of Maniraptoran dinosaurs and Achaeopteryx. They were found to possess breathing structures called as uncinate processes as in birds. The dinosaurs which were examined were found to have long uncinate processes as in diving birds.

This also proves that dinosaurs were highly active animals.
