As per recent reports, it has been unveiled that fossilized skeletons of two monstrous creatures, a dinosaur and a three-horned plant eater have been found. The fossils have been found in the region of Hell's Creek.

It is said that they both had entered into a battle that killed them some 67 million years ago. Scientists were of the view that when they look at the fossil then it gives a hint of a smaller version of Tyrannosaurus rex.

Scientists said that they thought the same due to head and large limb. One thing that scientists have realized is that T. rex shared habitat with its smaller cousin known as Nanotyrannus.

Philip Manning, one of the members of the research team from the University of Manchester, was of the view, "T. rex has distinctive features, one being its very tiny arms. When you look at this specimen you can see the forearms are very large. The hand of Nanotyrannus is huge".

This confirms that Nanotyrannus is real, which was a matter of debate for a long time. It has now been unveiled that that rock containing the fossils might become part of an auction that could fetch up around $US9 million.
