CHILESAURUS IS MISSING LINK IN DINO FAMILY TREE.

Researchers said on 16th August, 2017 (Wednesday) an oddball, vegetarian dinosaur with silhouette of a flesh-ripping velocireptor, whose fossilised remains were unearthed in Chile 13 years ago, was a missing link in dino evolution. Researchers from the University of Cambridge and the Natural History Museum in the United Kingdom used a dataset to analyse over 450 anatomical characteristics of early dinosaurs and correctly placed the creature, known as Chilesaurus, in the dinosaur family tree. The results, published in the journal Biology Letters, suggest that Chilesaurus effectively fills a large gap between two major dinosaur groups, and shows how the divide between them may have happened. Chilesaurus, which lived about 150 million years ago, has an odd collection of physical characteristics. Its head resembles that of a carnivore, but it has flat teeth for grinding plant matter. 
"Chilesaurus almost looks like it was stitched together  from different animals, which is why it baffled everybody", said Matthew Baron, a Ph.D student at Cambridge. Early research suggested th dinosaur belonged to the group Theropoda, the 'lizard-hipped' group, but the new study said it was probably an early member of Ornithischia group or the 'bird-hipped' group.
However, Chilesaurus does not possess the distinctive 'beak' like bird-hipped dinosaurs, researchers said. "This shows in bird-hipped dinos, the gut evolved first, and jaws evolved later - it fills the gap quiet nicely", Baron said.
