Awesome Dino had comical Arms

Dinosaurs Arms
With its blade-like teeth and frightening claws, Majungasaurus crenatissimus was one of the world’s most formidable predators, but new study reveals that it also obsessed some of the animal kingdom's negligible and most peculiar arms.

Tyrannosaurus rex and other well known greedy dinosaurs also had condensed forelimbs. While Majungasaurus, which lived 66 million years ago in Madagascar, was not a close T. rex family member, some lifestyle factors might have caused them to develop convinced similarities.

"The development of small arms in greedy dinosaur’s remains secrecy, but fossils like this is a significant sign in understanding the process,"

"Only by discovering the stops foremost from 'normal' longer arms in the family forms, to the short and strange ones in Majungasaurus and its close relatives, can we trust to clarify the evolutionary series and its causes."

The forearm skeletons are only a quarter of the length of the higher arm bones, but would have been broad and brawny. The wrist bones, however, aren't even ossified, and the short fingers probably lacked claws.
