The Royal Tyrrell Museum is helping city officials to identify the fossils.
Museum officials say finding dinosaur bones in Canada’s Alberta province is a relatively common occurrence.
“I can go out on a hike on a Sunday and find a dinosaur bone. But it’s really a question of how significant the find is,” said Leanna Mohan, the museum’s marketing coordinator.
Andy Neuman, the executive director of the museum, said that although dinosaur bones had been discovered in Edmonton in the past, this was the first time the city of Edmonton has made the discovery. …
Mr Neuman said workers will now continue to dig out bones still stuck inside the walls of the tunnel.
The Albertosaurus, a close relative of the Tyrannosaurus rex, was a top predator several million years ago, according to the Tyrrell Museum.
The first Albertosaurus was found by Joseph Tyrrell in 1884 in the Red Deer River Valley in Alberta, Canada.
The Albertosaurus is the most common of the large carnivores found in the Canadian province.
