The skin impression found on a Triceratops skull found by Charles Sternberg in Saskatchewan, Canada, is quite a surprising discovery, potentially giving people an idea of what the skin of Triceratops looked like, because no other Triceratops specimen has skin impressions preserved. The Tyrannosaurus rex skin impression found last year isn't too far from how T. rex is depicted in children's movies, and the newly discovered Triceratops skin impression may or may not be close to how kids illustrate Triceratops, while giving clues to what ceratopsid skin looked like.
