Dinosaur Mummy Mystery Unveiled with Help from Great-Grandmother

A recent study published in the journal *Science* sheds new light on the appearance of the Edmontosaurus annectens, a duck-billed dinosaur from the Cretaceous period. Paleontologist Paul Sereno, from the University of Chicago, led the research, which focused on a historic site in Wyoming where a famous dinosaur mummy was discovered in 1908.

Sereno's team meticulously examined the dinosaur's remains, revealing details such as hooves and a spiky tail. The research involved a unique approach, including archival research and conversations with local ranchers. The team was able to locate the original excavation site by tracking down a post office that was once run by a rancher's great-grandmother. This allowed Sereno to pinpoint the location where the dinosaur mummies were found.

The study highlights the exceptional preservation of the dinosaur's bodies within a thick layer of river sand, creating what is known as "the mummy zone." The mummies are not the same as Egyptian mummies, but rather fragile clay templates that captured vital details of the dinosaur's form. The study provides a comprehensive understanding of the Edmontosaurus, from its bill to its tail, including the crest on its back. The team studied two specimens, an adult nicknamed "Ed Sr." and a juvenile dubbed "Ed Jr."

The findings have been praised by other experts in the field, including Clint Boyd, the paleontology program manager for the North Dakota Geological Survey. Boyd noted that the study provides a valuable baseline for understanding dinosaur mummies and will drive future research. Sereno's work underscores the ongoing potential for new discoveries in paleontology, encouraging young enthusiasts to pursue their interest in the field.

BNN's Perspective: This research is a fascinating example of how interdisciplinary approaches, combining historical research with scientific analysis, can unlock new insights into the past. The meticulous work of the researchers, coupled with the unexpected assistance from local communities, highlights the importance of collaboration in scientific endeavors. The study's findings not only enhance our understanding of dinosaurs but also serve as an inspiration for future generations of paleontologists.
