About Us

Our permanent location can be found in downtown Wausau, WI at the Wausau Center Mall.


It’s simple:  To serve and educate as many people, primarily children, about our planet and the creatures that have lived on Earth throughout its 4.6 billion year history.  We are an educational, science-based organization and we teach children about concepts such as evolution and natural selection.

Our Goal

With a collection of museum quality fossils and fossil replicas, Colossal Fossils teaches people about fascinating plants and animals.  The collection contains fossils from many dinosaurs, mammals, plants, and corals.  We have fossils that range from tiny shells to the fearsome Tyrannosaurus rex.  From mammoth tusks to giant bear skulls, and each year, the collection grows larger.

Our Fossils

We have a wide range of different programs that can be modified to meet your specific needs.  For a list of our available programs, which are designed to meet and exceed Wisconsin’s educational standards, click here.
