article_snippet.sent: A new lineage of dinosaur that grazed on plants, despite being closely related to notorious carnivore Tyrannosaurus rex, has been discovered in Chile.
article_snippet.sent: Experts initially thought Diego had unearthed several species, due to Chilesaurus unusual combination of features.
article_snippet.sent: Most of the specimens discovered are the size of a turkey, but some isolated bones reveal the maximum size of Chilesaurus was around 10 feet (three metres) long, according to Chilean and Argentinian palaeontologists from institutions including the University of Birmingham who have studied the skeletons.
article_snippet.sent: The different parts of the body of Chilesaurus were adapted to a particular diet and way of life, which was similar to other groups of dinosaurs.
article_snippet.sent: As a result of these habits, different regions of the body of Chilesaurus evolved resembling those present in other, unrelated groups of dinosaurs - a phenomenon called evolutionary convergence.
article_snippet.sent: Chilesaurus represents one of the most extreme cases of evolutionary convergence.
article_snippet.sent: Chilesaurus fossils were found at the Toqui Formation in southern Chile, marked with a red star on the map, right .
article_snippet.sent: Chilesaurus provides a good example of how evolution works in deep time and it is one of the most interesting cases of convergent evolution documented in the history of life. '
article_snippet.sent: Chilesaurus shows how much data is still completely unknown about the early diversification of major dinosaur groups.
article_snippet.sent: Chilesaurus believes that this study will force palaeontologists to take more care in identifying fragmented and isolated dinosaur bones.
article_snippet.sent: Dr Fernando Novas, of the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires, Argentina, led the research on Chilesaurus.
article_snippet.sent: Experts initially thought Diego had unearthed several species, due to Chilesaurus unusual combination of features.
article_snippet.sent: Chilesaurus is the first complete dinosaur from the Jurassic Period found in Chile and represents one of the most complete and anatomically correct documented theropod dinosaurs from the southern hemisphere.
article_snippet.sent: Chilesaurus was an odd plant-eating dinosaur only to be found in Chile.
article_snippet.sent: However, the recurrent discovery in beds of the Toqui Formation of Chilesaurus bones and skeletons clearly demonstrates that Chilesaurus was, by far, the most abundant dinosaur in southwest Patagonia 145 million years ago.'
