Ancient Treasures: Discover Fossilization

October 18, 8:30am - 10:00am PDT. Hosted at Mission Science Workshop

part of a series on Flow


About this FieldTrip

Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in sediments of mud and silt.

One of the most important fossil sites in North America is found at Green River, located in western Colorado, eastern Utah and southwestern Wyoming. The Green River Formation is best known among paleontologists, the scientific community, and collectors for it’s perfectly preserved fossils of palm trees, turtles, birds and an abundance of fish. On numerous occasions, some of the best-preserved fossils were discovered here.

Thanks to the Mission Science Workshop, in this 60min hands-on workshop, you’ll learn about ancient geology and fossil formation by uncovering 60 million year old fish fossils imported directly from the Green River Formation in South West Wyoming.

Participants will handle Green River Formation rocks and use small chisels and hammers, brushes, and dilute (safe) hydrochloric acid to uncover fossils from these ancient treasures. Fossils are yours to take the home.

All materials will be supplied, just bring your curiosity!

As always, breakfast bites, coffee and smile are free :) In the practice of sustainability, please bring your coffee cup, thermos!
