In an article printed Thursday, paleontologists stated that they had found a brand new apex predator with an enormous head and little arms, like these of the Tyrannosaurus rex.
The findings have been printed within the journal Present Biology and recommend that the small entrance limbs weren’t an accident of evolution however quite helped the creature survive in its period.
Meraxes gigas, named after a dragon within the Recreation of Thrones books, was excavated over 4 years of discipline expeditions in northern Patagonia, Argentina. The cranium was first present in 2012.
