The Hamilton Quarry Assemblage is a fascinating display. An entire ecosystem was preserved in these 320 million year old Pennsylvanian rocks. Included in the assemblage are plants, insects, myriapods, water scorpions, fish, amphibians and other fossils. The site was brought to the attention of scientists by Walter Lockard, an amateur collector. Specimens from this site located only about 30 miles from Emporia are on display in museums worldwide. The top image displayed on this page is of a myriapod, an ancestor of the modern millipede. The lower image is of a slab of rock split on one of its bedding planes, revealing mirror images of a fish fossil.
