1 day agoHow a great-grandmother helped researchers unravel a dinosaur mummy mystery
You might not think a paleontologist looking for 66-million-year-old fossils would need to ask a rancher about his great-grandmother's job in the Wyoming badlands. But that's what Paul Sereno, a paleontologist at the University of Chicago, did when he was trying to track down a historic site where a famous dinosaur mummy was found in 1908. Sereno's work, published in the journal Science, brings new clarity about the appearance of the duck-billed Edmontosaurus annectens, a massive herbivore from the Cretaceous period.
