I’ve just returned from a Turonian dinosaur hunt in New Mexico! Dinosaurs from this age are extremely rare in North America (and globally as well). Sea levels were at their highest at this time and much of North America was either totally submerged under the Western Interior Seaway, or were rapidly eroding highlands that are gone today. In the United States, New Mexico is the place to be if you want to find dinosaurs from this age, so we spent two weeks checking out the Moreno Hill and Crevasse Canyon formations in the western edge of the state.
Elsewhere in the Mesozoic, parts of the field crew were working away at Cretaceous dinosaurs in the Mussentuchit Member of the Cedar Mountain Formation. In may we worked at Crystal Geyser Quarry, which is in the Yellow Cat Member of the same formation and is about 125 million years old, in a part of the Cretaceous called the Barremian. In contrast, the Mussentuchit Member is about 98 million years old, or Cenomanian in age. The Cedar Mountain Formation is a giant unit of rock, and the dinosaur faunas changed dramatically throughout!
The University of Alberta has a pretty active Palaeontological Society with undergrad, grad student, and faculty members, and when we can we try to organize palaeo-themed field trips. Lucky for us, this summer Edmonton had a very cool new dinosaur attraction open called the Jurassic Forest, so of course we had to check it out.
Drumheller, the town where the Tyrrell Museum is located, is a great town full of concrete dinosaurs and badlands scenery. Most tourists likely see it only in the summer, but I find myself there more often in the winter. It’s often very cold, but the snow in the badlands is quite nice, so here are a few photos from various winter trips to Drumheller.
