The first species that comes to mind when people think of a small-armed dinosaur Tyrannosaurus Rex or better known as T-Rex. On the other hand, a new species from the same family attracted attention with its arms even smaller than those of the T-Rex. This newly discovered abelisaurus species had very short and thick arms.

Discovered in Argentina and known as the “carnivorous bull” Carnotaurus This interesting species, similar to its genus, was scientifically discovered for the first time. K. inakayali This species, as it is called, has no horns and its arms are smaller, but remains of both species have been discovered in rocky structures in the Patagonia region.

His arms touched his chest as he ran

The fossil discovered by the researchers didn’t actually have complete arm bones, but these dinosaurs’ motionless elbows, primitive wrists and small arms even touched their chests as they ran. In the late Cretaceous period, approximately Between 66 million and 90 million years ago abelisaurus species were the most common creatures in the world. The most complete and important examples of these creatures, which also lived in North America and Asia, were discovered in South America.

Scientists wonder why these species are like this small and dysfunctional arms They have no clear explanation for what they have. While some researchers think that the arms of these dinosaurs began to atrophy during the evolutionary process, some researchers think that they evolved such arms to hold their mates and attack them with their claws during the reproductive process.
