Amazing story of Argentina’s dinosaur that had feeble arms but fearsome bite!

The mention of dinosaurs usually brings up the image of big and/or fearsome creatures walking around on their four limbs but now scientists have come across an unusual type which has hardly any forearms as reported in sciencealert.com.

This new species has been discovered by palaeontologists in Argentina and has been christened as Guemesia ochoai and determined with the help of a single skull. This has been suggested to belong to the family of abelisaurids – carnivores that had tiny arms and were found in India, Africa, Europe and South America. This group disappeared nearly 66 million years ago.

G. ochoai’s skull discovered in Argentina’s northwest region is dated to be about 70 million years old and is one of its kind and what distinguishes it from other abelisaurids is its “remarkably small” braincase. This creature whose brain was 70 per cent of Carnotaurus genus which roamed South America’s southern tip was in fact the smallest-brained abelisaurids.

Going by its Patagonian counterparts, this new found animal’s arms dangled on the sides of its broad chest uselessly. These could neither bend nor were there any claws on them.
