DENVER – The Denver Museum of Nature and Science celebrates its largest donation of dinosaur fossils: more than 6,000 bones from the ancient East Edmontosaurus Wyoming.

The bones, which include skulls, vertebrae and other limbs, have been collected on private land for several years by the Hankla family of Danville, Kentucky.

It goes without saying that the DMNS staff is very happy with the donation.

"These fossils are spectacular!" Said Joe Sertich, curator of dinosaurs at the Museum. "The donation is one of the largest collections of dinosaur bones from a single bone bed and includes skulls and other remains of dozens of individuals, allowing us to study how dinosaurs changed as they grew and how they varied within a single population."

The Edmontosaurus was a duckbill herbivore that wandered through western North America at the end of the Cretaceous Period between 66 and 68 million years ago.

These dinosaurs could grow to be over 40 feet long!

The fossils in this donation come from a huge bony bed where the animals were probably buried by a sudden flood event in eastern Wyoming nearly 67 million years ago.

Often, when fossils are discovered on private lands, as is the case with these bones, the remains can be dispersed to collectors from all over the world.

Instead, these 6,000 fossils will join other dinosaur remains from the Cretaceous at the Denver Museum of Nature and Science, including those recently found at a work site in Thornton.
