We're happy to announce this year's line-up of Guest Speakers:

On Saturday it will be:
1:00 PM - Jack Kallmeyer, serious fossil collector & president of the Dry Dredgers for 25 years
“The Classic Cincinnatian, Fossils from Abundantly Common to Fascinating Rarities”

The area around Cincinnati, Ohio, is one of the world’s richest for fossil collecting. The
rocks there were deposited late in the Ordovician Period, some 220 million years before the
first dinosaurs, and include brachiopods, bryozoans, corals, clams, crinoids, cephalopods,
snails, trilobites, and more. Mr. Kallmeyer will discuss the wide range of these fossils, and
explore both the common and unusual specimens.

3:00 PM - James St. John (School of Earth Sciences, Ohio State University at Newark)
"Ohio Minerals"
Many dozens of different minerals can be found in Ohio – about four dozen of them occur
