Wendy Sloboda spent much of her youth exploring the Warner area of southern Alberta. As a high school student in 1986, she worked as an assistant under the direction of Dr. Len Hills at the University of Calgary on a palaeontological impact assessment for a proposed dam near Milk River. She came across abundant dinosaur eggshell fragments on the Milk River Ridge near her home, and reported them to Dr. Hills. A team from the Royal Tyrrell Museum, including Dr. Philip Currie, visited the site with Wendy and her parents to inspect the find.

Dinosaur Cold Case

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.
