First Alaskan juvenile predator fossil adds insight to dino migration

(Southern Methodist University) The discovery of the first juvenile dromaeosaurid lower jaw bone 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, according to new research by SMU paleontologist Anthony Fiorillo. The research was published today in PLOS ONE. Prior to this find, only tiny dromaeosaurid teeth have been discovered in this region.
