Baby Dinosaur Fossils Show That Some Dino Families Called the Arctic Home

This discovery changes our understanding of the adaptive nature of dinosaurs. The earlier opinion was that dinosaurs lived in environments that were filled with sunlight and forests and lakes. To escape the heat, they would migrate to colder Arctic lands. However, this discovery has changed all these beliefs. Since the fossils found are of baby dinosaurs and others who hadn’t yet hatched, it proves that some dinosaurs called the Arctic their home. If the fossils had belonged to adult dinosaurs, it could still signify that these dinosaurs migrated to the Arctic. However, the presence of pre-hatched eggs and baby dinosaurs signifies that the Arctic was their breeding ground. The scientists determined the dinosaurs lived their entire lives in the Arctic, once they discovered they were nesting there. According to their prior studies, these dinosaurs’ incubation periods span from three to six months. Because Arctic summers are short, the dinosaurs’ children would be too immature to migrate in the fall if they deposited their eggs in the spring. During the Cretaceous period, global temperatures were significantly warmer, but the Arctic winters would have included four months of darkness, cold temperatures, snow, and little new flora for food. However, despite all of this, the children of these dinosaurs were born there, showing that they were local inhabitants of the Arctic.
