'Most bizarre dinosaur ever found' is missing evolutionary link – study

Originally classified as a relative of T rex, analysis shows Chilesaurus belongs to a different dinosaurian group, with implications for the dinosaur family tree

An unusual vegetarian dinosaur with the silhouette of a flesh-ripping velociraptor, whose fossilised remains were unearthed in southern Chile 13 years ago, is a missing link in dinosaur evolution, researchers have said.

A revised assessment of the kangaroo-sized Chilesaurus diegosuarezi , reported in the journal Biology Letters, bolsters a theory unveiled earlier this year that threatens to upend a long-standing classification of all dinosaurs.
