Exceptionally preserved dinosaur “mummies” discovered in Wyoming’s fossil-rich badlands are offering rare insights into prehistoric life.

In the fossil-rich badlands of Wyoming, paleontologists have uncovered two remarkably preserved Edmontosaurus fossils—massive duck-billed dinosaurs that lived around 66 million years ago. Found in a region now known as the “Mummy Zone,” these specimens contain rare traces of skin, muscle, and even hoof-like foot structures. The extraordinary preservation is giving scientists a closer look at the anatomy and adaptations of these Late Cretaceous giants, revealing new details about how they lived, moved, and survived in prehistoric North America.
