It turns out, T-Rex's relatives was the plant eaters

When we heard the news about the Tyrannosaurus rex (T. rex) generally are reminded of a very large body size, has a fierce and ferocious face. However, the impression is quite different from the fossils of T-Rex 's relatives that found in Chile.

Chilesaurus diegosuarezi walked on its hind legs 
as other theropods did. It also had robust forelimbs 
that looked like those of other Jurassic theropods, 
such as the Allosaurus, the researchers said.

Chilesaurus diegosuarezi is the relatives of Tyrannosaurus rex alias the renowned ancient carnivorous meat eater. However, Chilesaurus diegosuarezi was not follow the footsteps of their relatives, and evolved into herbivores.

"When I saw the shape of the bones, there seems to be different," said Fernando Novas, one of the researchers of Berbardino Rivadavia Museum of Natural Sciences in Buenos Aires, Argentina.

He argues, this dinosaur seem unusual because different combinations of the three types of groups other dinosaurs.

When it was in 2010, two geologists found several fossils around Chile. One is Chilesaurus diegosuarezi. Since these findings, the Chile and Argentina cooperate researching dozens of fossil Chilesaurus.

Although not all parts of the dinosaur was discovered, researchers found something different. Chilesaurus had a small skull, long neck but large, and the legs are not straight. "Chilesaurus's legs is to walk, not for run," said Novas.
Chilesaurus diegosuarezi has characteristics of three different dinosaur groups. Its pubic bone points backward like that of an ornithischian dinosaur, perhaps because it provided the gut more surface area with which to digest plant matter, the researchers said.

Meanwhile, according to Thomas Carr of Carthage College in Wisconsin, Chilesaurus an amazingly unique species. Because, through Chilesaurus findings can be known about the evolution of dinosaurs. Such as the type of theropod dinosaurs that walked on foot and meat eaters, it can evolve into herbivores or plant eaters.. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]
