The fossil’s black tint is believed to be caused by large amounts of manganese present in surrounding groundwater during fossilization, similar to the Royal Tyrrell Museum’s ‘Black Beauty,’ a Tyrannosaurus Rex fossil found in the same region. (Royal Tyrrell Museum of Paleontology)After seven years of work, the best preserved and most complete triceratops skull coming from Canada — also known as the “Calli” specimen — is on display for the first time since being found in 2014 at the Royal Tyrrell Museum in Drumheller, Alta.
A museum new release calls the specimen “unique” because of where it was discovered, the age of the rock around it, and how well it was preserved.
