 | Devil’s Coulee is the richest dinosaur nesting site in Canada and the third nesting site discovered in North America. The site was found in May 1987 near Warner, Alberta when ten fossilized Hadrosaur eggs were found. The site was designated a Provincial Historic Resource the same year. |  Finds at the site include young dinosaurs, eggs, embryonic bones, and nests of hadrosaurs. |
 | The find dates from the Late Cretaceous. (100-65 mya). Hadrosaurids, or duck-billed dinosaurs, were a common herbivore in the period.
The Royal Tyrrell Museum reports the Devil’s Coulee site is rich with ancient nests of at least two separate duck-billed dinosaurs and five different Cretaceous-era carnivores. |  The Devil's Coulee area was once part of a vast inland sea. |
