About Us

The Bighorn Basin GeoScience Center is dedicated to the study, conservation, and appropriate display of the northern Bighorn Basin’s natural resources, and to the promotion of geoscience and local historical and educational activities. We offer exhibits and educational materials for educators, geoscientists, tourists, and the people of Wyoming. We are a non-profit, tax-exempt 501(c)(3) corporation.

Founded by Cliff and Row Manuel, the Center operates the GeoScience Center museum in Greybull and holds events and offers workshops for educators and others every summer. Click here to read more about our events, workshops, and tours.

The Museum

The Center has recently opened the Museum of Ancient Life in downtown Greybull, Wyoming to house and display some of our fossils and reproductions in the context of the environment that was prevalent in the timeframe the animals existed. The museum features a 40 foot mural depicting the landscape, flora, and fauna of the Bighorn Basin of Wyoming as we understand it was about 150 million years ago. Painted by noted Powell, Wyoming artist Michael Kopriva, this mural is adjacent to, and complements, a display of actual fallen trees, rocks, and plantings that was created by Lori, owner of both the Crazy Woman Trading Post establishment (located across the street from the museum) and the building which houses the museum! Stop by to enjoy our displays and learn more about the geological and paleontological history of our area.

The northern Bighorn Basin of Wyoming contains extensively documented fossil deposits dating 550 million years ago (Cambrian Period) to the present. These include world famous localities with extensive fossil deposits that contain dinosaur bones, eggshells and trackways, as well as primitive mammal fossils. These deposits are located on privately held land as well as on state and federal land.

Major fossil discoveries have been, and are currently being, collected and removed from this part of the Bighorn Basin because suitable preparation, storage and display facilities do not exist in our area.

Professional scientists, including world famous geologists, paleontologists and anthropologists, have conducted research activities in this area for over 100 years. These research activities are only loosely coordinated among entities, and thus the rich natural resources of the area remain relatively unknown to the people of Wyoming. More importantly, the relationship of these resources and the Bighorn Basin remains disconnected in the minds of the world.
