Steps in Stone: Walking Through Time is a new exhibition that features real fossil tracks and trackways from the University of Colorado Museum of Natural History collections. Interactive elements invite children and adults alike to explore how animals moved across the earth, how their tracks became fossils, and how we study tracks to learn more about ancient landscapes and animals. The museum is hosting a free family day for children and adults to explore and learn about fossil tracks. Saturday | Nov. 15 | 10 a.m. - 4 p.m.
