Argentina scientists unearth dinosaur with ‘puny arms’ and hard head

Dinosaur probably belongs to carnivorous group called abelisaurs and may have used its head to ram its prey

Scientists in Argentina have unearthed the remains of a previously unknown species of meat-eating dinosaur that lived about 70m years ago that had puny arms and may have used its powerful head to ram its prey.

The fossil skull of the Cretaceous period dinosaur, named Guemesia ochoai, was discovered in Argentina's north-western Salta province. The researchers said it likely belongs to a carnivorous group of dinosaurs called abelisaurs, which walked on two legs and possessed only stub-like arms, even shorter than those of North America's Tyrannosaurus rex.
