Juvenile dromaeosaurids 70 million years ago in Alaska
Juvenile dromaeosaurids on the Prince Creek Formation in northern Alaska 70 million years ago. A group of predatory dinosaurs closely related to birds, Dromaeosaurids were thought to be migratory, but the discovery of a lower jaw bone of a juvenile dromaeosaurid on the North Slope of Alaska supports a growing theory that some Cretaceous Arctic dinosaurs did not migrate with the seasons but were year-round residents.
