Marine Reptile Fossilized Remains Found at Suncor’s Millennium Mine

The Royal Tyrrel Museum is studying the remains of a marine reptile discovered at Suncor’s Base plant.

Earlier this year, fossilized remains of a plesiosaur, expected to be between 105 and 110 million years old, were found at Millennium mine.

The Museum in Drumheller, one of the top dinosaur and marine reptile museums in the world, is now examining the fossils.

“Plesiosaurs were reptiles fully adapted for an aquatic life, but went extinct at the same time as the dinosaurs,” said Don Henderson, curator of dinosaurs at the museum, in a release.

This is not the first fossil found at Suncor’s Millennium mine. Back in 2011, an employee found the remains of a nodosaur which palaeontologists believe is the world’s best-preserved armoured dinosaur.

Remains of a plesiosaur were also found at Syncrude’s base plant back in 2017.
