While abelisaurids resembled T-Rex in general appearance with tiny stubby arms, they had unusually short, deep skulls which often bore crests, bumps and horns.<\/p>\n<p>&#8220;A peculiarity of this dinosaur is that it has cavities in the ear area that other abelisaurids did not have, which could have given this species different auditory capacities, possibly a greater hearing range,&#8221; Gianechini told Reuters.<\/p>\n<p>The elephant-size\u00a0dinosaur\u00a0had a strange, short skull with rough bones, so in life its head had bulges and prominences similar to current reptiles such as the Gila monster or some iguanas, the study shows.\u00a0<\/p>\n<p>However it may have lived, the fossil evidence of Llukalkan&#8217;s adaptations suggests that abelisaurids were flourishing right before the dinosaurs went extinct.<\/p>\n<p>&#8220;These dinosaurs were still trying out new evolutionary pathways and rapidly diversifying right before they died out completely,&#8221; said study co-author Ariel Mendez from the Patagonian Institute of Geology and Palaeontology in Argentina.<\/p>\n<p>The study was published in the peer-reviewed\u00a0Journal of Vertebrate Paleontology.<\/p>\n<p>Source: <a href=\"https:\/\/www.usatoday.com\/story\/news\/nation\/2021\/03\/31\/dinosaur-discovery-new-species-the-one-who-causes-fear\/4823612001\/\" target=\"_blank\" rel=\"noopener noreferrer\">Read Full Article<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Story Highlights These groups of dinosaurs were flourishing right before they went extinct.
