Fossil found in US could help unravel mysterious dinosaur riddle

Melbourne, Sept. 10 : A fossil featuring two dinosaurs, one a top predator and the other a massive three-horned plant eater, could help unravel a mystery about a new type of dinosaurs.


It can be seen in the fossil that the carnivore had its skull smashed while teeth can be seen embedded in the neck of its prey, a Triceratops.

Their fossilised skeletons were found together in a remote and arid region of Montana known as Hell's Creek.

Taking one glance at the fossil, the six- to seven-metre long, two-legged meat eater looked like a smaller version of Tyrannosaurus rex, but there are differences, in particular the animals' graceful head and large forelimbs.

Scientists believe that the fossil has provided clear proof that T. rex shared its habitat with a smaller cousin, Nanotyrannus, similar to how lions and cheetahs hunt together on the African savannah, News.com.au reported.

The discovery could help end the debate among experts, who believe in Nanotyrannus, and the others who claim that the animals' fragmented fossils belong to a juvenile offspring of T. rex.
