What were mammals eating during the Age of Dinosaurs, and what can we learn about their diets from studying fossils of their teeth? Those and other questions will be answered as the "The Fossil Guy" series continues Saturday, April 27, at 2 p.m. at the University of Iowa Museum of Natural History.

Each “Fossil Guy” program consists of a 30-minute talk by Don Johnson, a local amateur paleontologist, followed by a question-and-answer session. The free public programs are geared toward elementary-age children and are held in Macbride Auditorium.

April’s presentation is titled “The Rise of the Mammals” and will feature skulls of mammals that lived in the Western United States 30 millions years ago. In addition, participants will be able to see and touch replica and mineralized bones, skulls and jaws of Ice Age mammals, including saber-tooth cats, dire wolves, cave bears, bison, giant deer, ground sloths, armored glyptodonts, mammoths, and mastodons.
