Members of a City of Edmonton, Alberta, drainage crew first thought they had found some interesting rocks, but it is now believed they uncovered dinosaur bones and a tooth.
The Edmonton Journal reported that Ryley Paul and Aaron Krywiak were using a jackhammer in a sewer tunnel area, nine storeys below the surface of a street, when they came across some unusual items. They didn’t look too closely until they found the tooth.
“I was pretty surprised. I heard from other people working here 30 years that they have never found anything,” 21-year-old Krywiak, told the Edmonton Journal. “It was pretty cool. I never thought I would have a dinosaur tooth in my hand.”
When they first uncovered the tooth it was black, but after about 20 minutes it appeared brown and shiny.
Police were called and it was determined the bones were not human.
Jack Brink, curator of archeology at the Royal Alberta Museum and Mike Burns, a PhD student in paleontology from the University of Alberta, went below ground and found more bones.
It is believed that the tooth came from the mouth of Albertosaurus, the ‘Alberta lizard’, which was a meat eating member of the Tyrannosauridae family. Some large bone fragments are thought to be from the plant-eating Edmontosaurus.
Donald Brinkman, director of preservation and research with the Royal Tyrrell Museum, said it is not uncommon to find dinosaur fossils around Edmonton.
An expert from the Royal Tyrrell Museum or University of Alberta is now on site while work is being done, to ensure fossils are preserved without causing construction delays if there are any more finds.
