A research group has found a new species of dinosaurs in Alaska, this duck-billed prehistoric creature being able to resist during the long months of cold nights and maybe experienced snowfall. The Americans say that the distant place they are discovering might hold have a lot more dino fossils.
Paleontology is a pretty intense work, mostly when they want to discover dinosaurs that could endure cold harsh environments. To get to remote areas of Canada with places having many fossils of animals who roamed in the prehistoric Arctic regions, experts have to wait for those regions to unfreeze. Then arrive in small planes and go with their boats down the waterways surrounded by failing coves. When they reach the prehistoric site without an aircraft accident or a stream of rocks, they meet cold rainfalls, snowfalls and lots of nasty flying bugs — in addition to boars, wolves, bears and other scary animals.
The duck-billed dinosaur is a lot more interesting than your regular fossil discovery. The prehistoric creature, which was formerly considered to be a part of a popular variety of dinosaurs, was extremely numerous more than 65 million years ago. Experts have already discovered around 10,000 bone fragments from these animals.
The new creature, known as Ugrunaaluk kuukpikensis, is presented in a research released these days in the paleontology journals. At 25 feet in length, this plant eater seemed to be a close relative of the Edmontosaurus, the duck-billed animal discovered in Alberta. But the numerous bone fragments, which the scientists believe that are found in one area because a group of younger dinosaurs were killed, revealed enough little variations to raise their doubts. Specific researches performed by US experts confirmed that this creature was truly a new species.
When these dinosaurs roamed the Alaskan regions, their area would have an average temperature ranging in the mid 40s. For reptilian requirements, that is fairly cool for them, so paleontologists think that this variety of dinosaurs must have developed unique modifications to live in the colder climate. These were animals living at the limit of what people think that dinosaurs were capable to endure from a physical standpoint
The scientists are particularly enthusiastic about looking at how easily the new dinosaurs evolved, which might tell them if they used an uncommonly slowly metabolic rate to handle the very low temperatures. They can monitor development levels by studying the collections of prehistoric bone fragments, which are generally the same in many species.
In inclusion to cool climate and periodic snowfall, the animals also had to deal with darkness: the area was very dark for four to six months every season, and there are no indications that these dinosaurs moved to other warmer regions. The scientists already have proof of other varieties of dinosaurs living permanently in these unfriendly regions, and they believe that they will discover even more species, along with a few unidentified ones.
It is fascinating for experts to consider how dinosaurs lived through those periods of pitch-black nights. They are just discovering this entirely new range of dinosaurs that they did not know that they lived.
