A new study was published by researchers from Florida State University which challenges the notion that old dinosaurs were cold-blooded creatures that required tropical temperatures to survive. The paleontologists of the State University of Florida and the University of Alaska Fairbanks have published a new study, which finds that almost all types of dinosaurs, ranging from creatures in the form of small and massive birds Tyrannosaurus, not only reproduced in the Arctic but lived there all year round.
Researcher Pat Druckenmiller, Head of the Journal and Director of the University of Alaska Northern Museum, said the researchers clearly have dinosaur evidence nested in the Arctic. This study marks the first time that anyone demonstrated that dinosaurs were able to reproduce such high latitudes. The conclusions of the new study against past assumptions that dinosaurs migrated to reduce latitudes during the winter.
The researchers say that the conclusions provide convincing evidence that prehistoric creatures were warm. Druckenmiller and other researchers did work on the ground in Prince Creek’s training in northern Alaska for more than ten years. In this training, they destroyed the diversity of dinosaur species noting that most of them are new for science. Their last discovery provided evidence that dinosaurs lived near the ancient Ocean of the Arctic during the first stages of their lives.
The researchers have found tiny teeth, a length of less than two millimeters and seven species of perinatal dinosaur. The perinatal term describes babies dinosaurs that are either embryonic or hatched. Co-author co-author Gregory Erickson says one of the largest mysteries of Arctic dinosaurs was whether they were seasonally migrated in the North or lived there all year round. Erickson says the team unexpectedly found perinatal vestiges representing almost all types of dinosaur in the training, calling for a type of prehistoric maternity room.
Scientists will then try to identify and compare fossils with similar specimens of creatures that lived at lower latitudes such as Alberta and Montana. The team stated that previous research show the incubation period of the types of dinosaurs found between three and six months depending on the species. The Arctic summers are short, so if the dinosaurs put their eggs as soon as it warm up in the spring, the offspring would be too young to migrate in the fall. This suggests that they lived in the region all year round.
