What we found are likely Utah’s oldest fossils, possibly ranging in age from Mesoproterozoic to early Neoproterozoic (1.6 billion to 750 million years ago); pending radiometric data may help constrain their ages. These fossils also provide clues to the environment in which the organisms lived.

What are some weird facts about Utah?

Why is Utah rock red?
The red, brown, and yellow colors so prevalent in southern UT result from the presence of oxidized iron–that is iron that has undergone a chemical reaction upon exposure to air or oxygenated water. The iron oxides released from this process form a coating on the surface of the rock or rock grains containing the iron.
