Scientists had found the bones of these two enormous dinosaurs on the beaches of Morocco, together with four other bones from feared predators of a similar built. Researchers were puzzled as to how six predators who were on top of the food chain would have survived in the same area. This created one of the greatest riddles on dinosaurs; how did these six predators survive in the same location without destroying each other.
Abelisaurs may have had feathered bodies for the most of their frames. They may have been slightly smaller than the T-Rex due to bone structure. But from the physiology they were pound-for-pound just as vicious as their competitor.
"They may have looked a bit odd as they were covered in feathers with tiny useless forelimbs," according to Discovery News. "But make more mistake, they were fearless killers of their time."After closer examination of the femur bone of the Abelisaur and its exact location, it is evident that the riddle may be much straight forward than initially thought. The Predators may not have lived in the same environment. But through earth shifting and other tectonic movements the bones may have settled in the same layer due to similar density and structure.
