As one of the largest of the dromaeosaurids, Utahraptor ostrommaysorum perhaps first garnered significant public attention after starring in the 1999 animated documentary, Walking with Dinosaurs. Since this time, the scientifically accepted appearance of this 7m theropod has changed considerably, as more evidence has been unearthed supporting the idea that this creature was fully feathered – much like its far smaller kin.
