Scientists have made a groundbreaking discovery in the field of paleontology, uncovering remarkably preserved fossils of a large herbivorous duck-billed dinosaur, Edmontosaurus annectens, from Wyoming. The team, led by Paul C. Sereno, has shed new light on the appearance of this ancient creature, which lived during the late Cretaceous period.
The discovery consists of two mummies, remarkably well-preserved due to a unique geological process known as clay templating. This process involves frequent flooding of the area by a nearby river, which drowned the dinosaurs and covered their bodies with mud and clay that congealed around the biofilm forming at the surface of decaying carcasses.
The team's analysis revealed an updated image of Edmontosaurus, complete with changes to its crest, spikes, and skin texture. Perhaps most surprisingly, it shows hooves on its legs, adding a new layer of complexity to our understanding of these ancient creatures.
One notable aspect of the discovery is the size of Edmontosaurus' scales, which were incredibly small, measuring only 1-4 millimeters across. This challenges our previous understanding of these animals and has significant implications for the field of paleontology.
In addition to the Edmontosaurus mummies, the team also found fossils of two other dinosaurs: Tyrannosaurus rex and Triceratops. These discoveries are expected to be published in upcoming papers by Sereno's team and offer a glimpse into the diverse range of life forms that inhabited the region during this time period.
The study is a testament to the power of interdisciplinary research, combining geology, paleontology, and modern imaging techniques to uncover new insights into the natural world. As Sereno puts it, "We are in the age of discovery," highlighting the excitement and potential for future breakthroughs in our understanding of ancient life forms.
