Content Objective: I can use a map to identify fossil locations in Utah. Language Objective: I can write a paragraph about Utah’s past based on fossil locations.
Fossils are evidence of living organisms from the past and are usually preserved in sedimentary rocks.
Based on the fossils found in various locations, we can infer how Utah environments have changed over time (e.g., trilobite fossils indicate that Millard County was once covered by a large shallow ocean; dinosaur fossils and coal indicate that Emery and Uintah County were once tropical and swampy).
Examination of Utah stratigraphy reveals fossil rocks of every period from the Precambrian Proterozoic onward. Millard County alone has fossils from almost every period except, maybe the Jurassic and Cretaceous.
