Red Deer River shakedown: a history of the Captain Marshall field paleontological expedition to Alberta, 1922, and its aftermath

A 1922 paleontological expedition to Dinosaur Provincial Park, Alberta, yielded significant fossil discoveries that challenged long-held myths about its purpose and success. Led by Elmer S. Riggs, the team recovered notable specimens including a lambeosaurine hadrosaur (later displayed alongside Gorgosaurus) and a juvenile Gorgosaurus nicknamed 'Elmer.' Contrary to popular belief, the expedition was a valuable preparatory mission for a subsequent, more extensive South American fossil-hunting campaign, rather than an abandoned effort. The study relied on historical records and field notes to debunk misconceptions about Riggs' motivations and the expedition's outcomes.
