A new study has been published by researchers at Florida State University, which challenges the idea that ancient dinosaurs were cold blood creatures that required tropical temperatures to survive. Paleontologists from Florida State University and Alaska Fairbanks University published a new study that found that almost all types of dinosaurs, ranging from small and bird-like creatures to massive Tyrannosaurus, not only reproduce in the Arctic , but they lived there throughout the year.
Researcher Pat Duckenmiller, the lead author of the document and director of the Allaska University Museum, says that researchers have clear evidence, dinosaurs were annising in the Arctic. This study marks the first time that anyone has shown that dinosaurs could reproduce such tall latitudes. The findings in the new cross-section passed through dinosaurs migrated to the lowest latitudes during the winter.
Researchers say that findings provide some convincing evidence that prehistoric creatures were hot blood. Druckenmiller and other researchers have been doing field work in Prince Creek training in northern Alaska for more than a decade. In this formation, they have unearthed the diversity of dinosaur species, pointing out that most of them are new in science. His last discovery provided evidence that dinosaurs lived near the ancient Arctic Ocean in the early stages of his life.
The researchers found small teeth, some less than two millimeters in length and bones of seven species of perinatal dinosaurs. The perinatal term describes the dinosaurs of babies that are embryonic or have simply incubated. The Gregory Erickson Study Coauthor says that one of the most important mysteries about the dinosaurs of the Arctic was if they migrated seasonally to the north or lived there throughout the year. Erickson says that the team unexpectedly discovered the remains of perinatals that represent almost all kinds of dinosaurs in the formation, calling it a type of prehistoric maternity room.
Scientists will try to identify and compare fossils to similar specimens of creatures who lived in lower latitudes such as Alberta and Montana. The team says that the previous research shows the incubation period for the types of dinosaurs that are 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 was heated in the spring, the offspring would be too young to migrate in the autumn. That suggests that they lived in the region throughout the year.
