Detailed in a paper published by the New Mexico Museum of Natural History and Science, L.J. Krumenacker, adjunct professor of geosciences at Idaho State University, affiliate curator at the Idaho Museum of Natural History, and professor of geology and biology at the College of Eastern Idaho, Robert Gay, education manager at the Idaho Museum of Natural History and their co-authors, hypothesize a toe bone and braincase currently in the collections of the Idaho Museum of Natural History, and a skull and skeleton located at the Aathal Dinosaur Museum in Zurich, Switzerland, point to the possibility of there being one or more as yet identified species of dinosaurs that roamed Northern Wyoming 150 million years ago.
