(Phys.org)—A team of researchers with the Royal Ontario Museum and the University of Toronto, both in Canada, has unearthed what is being described as one of the most complete ankylosaur fossilized skeletal remains ever from the Judith River Formation in Montana. In their paper published in the journal Royal Society Open Science, the group describes the find and why they believe study will reveal more about the diversity of the creatures that roamed the Earth not long before the end of the dinosaurs.
