DINOSAUR DROMAEOSAURUS Silver Coin 4$ Canada 2010

Dromaeosaurus (meaning "running lizard") was one of two raptor species that lived in Alberta between 74 and 76 million years ago when the province and neighbouring 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. No two coins in this collection are exactly alike, thanks to the unique selective aging effect applied to each 99.99% pure silver coin. To ensure absolute accuracy, this design was approved by palaeontologists at the Royal Tyrell Museum in Alberta. Reverse: A Dromaeosaurus fossil in a stance that clearly reflects its predatory nature. The Ian Rank-Broadley effigy of Her Majesty Queen Elizabeth II appears on the coin's obverse.
