Dinosaurs, especially carnivorous species have always been a very captivating subject for science people. From the carnivorous family, the most known species is the infamous T-Rex. There are many fossils of this great prehistoric beast mostly found in the low-mild latitudes of Asia and North America.
But the new discovery seems to change what the scientists knew about Tyrannosaurs. They discovered a fossil of a new species of Tyrannosaur that lived 70 million years ago in the late Cretaceous era. These fossils were found in Alaska and it reveals a new smaller kind of Tyrannosaur but deadly just as well.
The new species of Tyrannosaur discovered is called Nanuqsaurus Hoglundi and it appears to be smaller than the great T-Rex, with an adult skull of about 25 inches, in comparison to the 60 inches T-Rex skull. The new research studies show that this species may have lived in an extreme weather in high-latitude continental environment in the northern edge of Cretaceous North American areas.
The scientists recovered the new species of Tyrannosaur fossils from Prince Creek Formation in Northern Alaska and analyzed the skull, jaw and maxilla, comparing it to other tyrannosaur known species. The new discovery may bring out some new insight regarding the evolution and adaptability skills of tyrannosaurs in a different, colder environment like the Arctic.
New Species Of Tyrannosaur can offer new information about the Prehistoric Arctic
Anthony Fiorillo from the Perot Museum Of Nature and Science in Texas says that the new “pygmy” tyrannosaur can give us more info on how the environment in the ancient Arctic looked like. The new study appeared in the Plos One journal and further explains: “Nanuqsaurus hoglundi also tells us about the biological richness of the ancient polar world during a time when the earth was very warm compared to today.” Details about the new species of tyrannosaur will be further revealed.
