2017 - $20 - 1 oz. Pure Silver Coin - Ancient Canada: Ornithomimus

Ornithomimus fossils, like the one depicted on your splash-struck coin, changed the way we think about feathered dinosaurs. By studying three specimens found in the Badlands of Alberta, paleontologists concluded that Ornithomimus was covered in down-like feathers that, as the dinosaur matured, developed into long feathers on its arms to form primitive wings. This suggests wings appeared much earlier in the evolutionary timeline—and were first used for display rather than flight!
