"Perlaku uncontrollably aggressive in modern vertebrates, not least (some) birds and crocodiles," said Joseph Peterson, who presented his research at the Society of Vertebrate Paleontology, North Carolina.

He said several vertebrate animals or vertebrates today also have aggressive behavior to attack enemies. For example, the crocodile has attacked the crocodile behavior of others using head movements, besides bird uses its beak to peck.
