New dinosaur fossils discovered near Grande Prairie

A deposit of dinosaur bones near the Pipestone River on June 22, 2022.

Paleontologists have excavated additional dinosaur fossils near Grande Prairie, Alberta, which should allow them to better understand the behavior of these reptiles.

Researchers from the Philip J. Currie Museum discovered a juvenile hip bone of a pachyrhinosaurus in mid-June in a deposit of bones near the River Pipestone south of Wembley.

There were also vertebrae, ribs and foot bones.

The discovery allows scientists to better understand this horned quadruped that resembles a rhinoceros. Everything we know about their behavior comes from fossils, says museum curator Emily Bamforth, who helped with the research.

“The bone deposits help us understand how these animals lived together, how they behaved in groups, their social structures, and how they lived and died.

During their excavation, the researchers also discovered the tooth of a tyrannosaur and that of a small theropod. They believe this bone bed is the result of a flood that killed these animals and caused them to descend into one place, near the Pipestone River.

We believe that this bone dump gathers a herd of pachyrhinosaurus, said Mrs. Bamforth. Not only do we have adults, but we have babies and teenagers. She points out that separating the bones will be difficult, because they are tight against each other.

This bed of bones, which has delighted paleontologists since the 1970s, inspired the opening of the Philipp J. Currie Museum in 2015.
