Mesa
County has been the site of important fossil discoveries for over a
century. These
include some of the largest, and some of the smallest dinosaurs in the
world. The earliest Brachiosaurus, and a largely intact
Apatosaurus are among the many significant dinosaur discoveries. The Bollan Stegosaurus, including tail spikes, was excavated at Rabbit Valley
by the Museum of Western Colorado. Mammal fossils of later
periods also are found, including mammoth and bison remains.
