This “rock” has been sitting in the basement of the family house for close decades. My grandmother Hazel Dawson found it back in the 1960s on a trip to the Alberta Badlands. This fall I sent a series of photos of the “rock” to Carl Mehling of the Fossil Amphibian, Reptile, and Bird Collections, Division of Paleontology at the American Museum of Natural History.
Mr. Mehling was kind enough to take a look and immediately confirmed that this was a dinosaur bone fragment. Unfortunately there is not enough of the specimen to identify the bone or the dinosaur type from which it came from suffice to say that the hadrosaurs (duck-billed dinosaurs) and ceratopsians (horned dinosaurs) were the most common species in that part of the world. Mr. Mehling stated “Your piece is most likely from within the Late Cretaceous and should be about 75-78 million years old.” Incredible and I thought it had been laying in the basement a long time.
