Currently at the Royal Tyrrell Museum of Palaeontology is arguably the world’s most fascinating (and best-preserved) armoured dinosaur. The Borealopelta markmitchelli was discovered by a worker in the Suncor Millenium Mine in 2011 and, at 112-100 million years old, is the oldest known dinosaur ever found in Alberta.
To learn about how this one-of-a-kind discovery happened, and how scientists at the Tyrrell worked to preserve it, you can watch Dinosaur Cold Case on CBC’s The Nature of Things right now! If you’re in Canada, click here to unravel this made-in-Alberta mystery.

I recently watched the Nature of Things episode about this dinosaur. It was certainly fascinating. I highly recommend it.
