PAGE, Ariz. - The National Park Service said a field crew recently discovered "extremely rare fossils" while documenting fossil tracksites at Lake Powell a Glen Canyon National Recreation Area in Utah.
Park rangers said the fossils were the first tritylodontid bonebed found in the Navajo Sandstone. They included bones and teeth.
The discovering has been described as "one of the more important fossil vertebrate discoveries in the United States this year." Rangers believe it will also shed light on the fossil history that was exposed on the changing shorelines of Lake Powell.
It's believed the fossils were from early herbivorous mammal-relatives from the Early Jurassic era, which was approximately 180 million years ago.

The fossils will be scanned with X-ray computerized tomography (CT) at the University of Utah South Jordan Health Center. They will further be studied at St. George Dinosaur Discovery Site at Johnson Farm (SGDS) with the help from Petrified Forest National Park and the Smithsonian Institution.
The fossils will then become part of the Glen Canyon NRA museum which will be housed at the Prehistoric Museum in Price, Utah.
"Studying these fossils will help paleontologists learn more about how early mammal relatives survived the mass extinction at the end of the Triassic Period and diversified through the Jurassic Period," the National Park Service said in a news release.
The public is invited to learn more about the discovery on October 11 for the National Fossil Day interpretive event being held at Zion National Park.
