Dromaeosaurus (or “running lizard”) was one of two raptor species that lived in Alberta between 74 and 76 million years ago when the province and neighboring Saskatchewan were the lush subtropical shore of a great inland sea. These dinosaurs ran upright on their two hind legs. They measured about 2.5 m (8.25 ft) from head to tail and would normally weigh less than 20 kg (44 lb). They had clawed hands on their fore limbs and sharp, recurved teeth that were perfectly designed for slicing into prey.

This coin features a captivating design of fossilized dinosaur bones with a selective aging technique that enhances the characteristics of these prehistoric creatures, giving the impression of a real stone fossil. Variations in tone and color are a direct result of this process. No two coins are alike.
