In a metropark in suburban Ohio, there are potentially hundreds of fossils right below our feet. We have mapped nearly 20 sites with fossils in these park, and suspect that they preserve a record of small and large animals from the late Pleistocene to today. At present, we have no idea how old these fossils are, but with your help, we will be able to use radiocarbon dating and pollen analysis to establish the age of these fossils and determine when they were deposited in the caves here.
