Nanuqsaurus holgundi (the full species name meaning is "Hoglund's polar bear lizard")[1] is a genus of pygmy sized dinosaur. It is only known from one specimen, DMNH 21461, a partial Skull roof found in Alaska. This dinosaur may have only grew to about 6 m (19.7 ft) long, which was half the size of Tyrannosaurus.


The skull would have been around 50 cm (1.65 ft) when complete.

What did Nanuqsaurus eat?

Nanuqsaurus lived in Alaska so it hunted Ugrunaaluk and juvenile Pachyrhinosaurus. In the summer, the prey numbers would have plentiful but they declined in the winter.
