Dinosaurs come in all shapes and sizes but there has been nothing quite so unusual as a species found in the Patagonian fossil fields of Chile, scientists have said.

A study of the 150m-year-old remains of a Tyrannosaurus-like dinosaur showed that although it shares many of the features of its more fearsome carnivorous cousin, it grazed exclusively on plants.

Scientists studying the anatomy of Chilesaurus diegosuarezi said that it is the “platypus” of dinosaurs because of its bizarre combination of specialised features normally seen in quite unrelated animals – similar to the egg-laying, fur-covered features of the duck-billed platypus.
