The Denver Museum of Nature & Science just got a bunch more dinosaur fossils.

The museum received its largest dinosaur fossil donation this month, accepting more than 6,000 bones that include skulls, vertebrae and limbs of edmontosaurus, also known as a hadrosaur, from eastern Wyoming.

The fossils, which come from dozens of individuals, were found in a massive bone bed on private land that was likely created when a sudden flood buried the duck-billed dinosaur 67 million years ago. It’s one of the largest collections of dinosaur bones from a single bone bed, according to museum dinosaur curator Joe Sertich.

“I am proud and excited to see these fossils end up at a major research institution like the Denver Museum of Nature & Science,” said John Hankla, one of the donors, in a statement. “Hopefully they can be used to inspire future scientists and can lead to significant scientific research on dinosaur growth and behavior.”

The Hankla family of Danville, Ky., had been gathering the collection for several years. John Hankla is now considered a research associate at DMNS given his ongoing outreach and research of Cretaceous period fossils in eastern Wyoming.

Many fossils from this region can disappear on the commercial market into the hands of collectors across the world, according to the museum. But these will join the museum to hang out with fossils from Montana, North and South Dakota, New Mexico, Utah and the metro Denver area.

Sertich said in a statement that the find will help the museum study how dinosaurs changes as they grew and how they varied within one population.

The fossils will be prepared in the museum’s paleontology lab for both research and future programs and exhibits. Several blocks of bones and teeth will be on display at the Dinosaur Gulch play area at Cherry Creek Shopping Center on Saturday
