The Green River forms a dramatic “gooseneck” near Sand Wash in upper Desolation Canyon. The river has incised into rocks of the Douglas Creek and Parachute Creek Members of the Tertiary-age Green River Formation, which comprises sediments that accumulated in ancient Lake Uinta.

Turret Arch viewed through North Window arch in The Windows Section of Arches National Park. The arches formed as the result of erosion through weak parts of sandstone fins composed of Jurassic-age Dewey Bridge Member of the Carmel Formation and Slick Rock Member of the Entrada Sandstone.

Remember the family of Utah Raptors that arrived in a 9-ton ‘block’ in Salt Lake City a few months ago? Our Paleontologists here at the UGS have been working very closely on this project for years. Check out this wonderful highlight on their work so far, where you can see interviews from Utah State Paleontologist James Kirkland, and Paleontologists, Don DeBlieux and Scott Madsen.

A nine-ton block of sandstone that was pulled from a Utah mountain late last year holds the biggest fossil trove ever found of the giant predatory dinosaur known as Utahraptor. Covered in feathers, with a huge sickle claw on each second toe, Utahraptor looked like a pumped-up version of the Jurassic Park star Velociraptor.

Reports of what looked like a human arm brought Utah state paleontologist James Kirkland to a particular sandstone hill in 2001. But it turned out that his graduate student had actually found something entirely different — a veritable mass grave of Utahraptor dinosaurs. Now they’ve found the remains of six individual dinosaurs, and there may still be more inside of the 9-ton sandstone block they’re excavating.

Late-winter ice still clings to the Colorado River near Big Bend, north of Moab. Boulders of Jurassic-age Wingate Sandstone and Triassic-age Chinle Formation line the banks of the river, eroded from the cliffs and ledges cut by the river as it has incised its channel over millions of years.

One of numerous slot canyons carved into Jurassic-age Navajo Sandstone in Zion National Park, Bear Trap Canyon is particularly dark and narrow. With little sunlight penetrating to the canyon floor, snow and ice often linger well into spring. Zion National Park, Washington County, Utah Photographer: Tyler Knudsen; © 2014

Birds are dinosaurs. This fact is easily understood by looking at the scaly feet of a chickadee or by comparing a chicken wing to a Velociraptor arm. But given that birds are the only “terrible lizards” around today, it’s easy to forget that they also thrived alongside their non-avian kin for 84 million years. The first birds evolved in the Late Jurassic, roundabout 150 million years ago, and they became a widespread and successful branch of the dinosaur family tree.
