The two large bones that were discovered almost 50 years ago have baffled experts for years. Some researchers thought these bones belonged to a frightening carnivorous dinosaur, while some believed that the bones belonged to an oversized sloth-like creature.

But now at last, the mystery has been solved. Scientists have reported that they have found the rest of the dinosaur and they have some new and really weird description of the dinosaur.

Scientists said that the dinosaur was much larger than it was earlier thought. It was a beast called Deniocheirus that lived 70 million years ago and belonged to an ostrich-like family of dinosaurs. At 14,000 pounds, it was 10 times heavier than its next-biggest relatives and it stood almost 16 feet high, taller than an elephant.

Scientists reported that the dinosaur had lanky back legs like an ostrich's, a toothless bill, an enormous hump on its back and also had a fan of long feathers on the end of its tail. The dinosaur fed itself on plants and fish, which made it the biggest omnivorous dinosaur.

Stephen Brusatte, a University of Edinburgh paleontologist, who is not connected to the new study, said, "For the last half-century, people have been going out to the Gobi Desert trying to find the rest of this animal. Thankfully, the reality of this thing turns out to be even crazier than what people were dreaming up".

Paleontologist Thomas Holtz of the University of Maryland said that they never suspected that the creature would look like a duck-billed ostrich camel.

Brusatte said that Deinocheirus is the biggest dinosaur which was an omnivorous.

Study co-author Yuoung-Nam Lee of the Korea Institute of Geoscience and Mineral Resources stated that he was totally stunned and thrilled. Lee said that he was very happy to find the creature he had been looking for in the Gobi desert.
