Kaiparowits Formation, Sedimentary formation in southern Utah, United States
The Kaiparowits Formation is a rock layer in southern Utah composed of alternating beds of mudstone and sandstone stacked over hundreds of feet. These deposits are visible today within the Grand Staircase-Escalante area and reveal ancient geological processes.
This formation developed during the Campanian age around 77 million years ago when the region featured swamp environments bordering a shallow sea. These conditions allowed sediments to accumulate and preserve remains of prehistoric animals.
Scientists from the Natural History Museum of Utah conduct research expeditions to collect fossils and document geological features of the formation.
The site lies within protected lands and requires proper preparation for visits. Anyone wishing to explore the area should check conditions and access information before going.
Paleontologists have discovered several dinosaur species within this layer, including Gryposaurus, Kosmoceratops, and Teratophoneus curriei. Despite these discoveries, much of the formation remains unexplored and likely holds additional fossils.
