Fossil Tours at Cave of the Mounds

The red arrow points toward the gastropod fossil. Gastropods are closely related to the snail of the present day. The shell is made of a form of calcium carbonate called aragonite. Aragonite dissolves more readily than limestone so oftentimes we see only a cast of a mold that fossilized and the shell dissolved.

Walk through an ancient ocean and look for fossils older than the dinosaurs. In a limestone cave, there are many fossils to see. Learn from our Cave Educator about different fossils that have been discovered. 

Fossilization is rare. According to the BBC, scientists estimate that less than one-tenth of 1% of all creatures on Earth become fossils. Feel like a geologist, archeologist, or paleontologist by looking for fossils along the cave trail.

Along your tour, collect some fossils to take home with you in a reusable bag. The fossils are similar to the ones you will find in the limestone of the cave.
