Wisconsin Ordovician Hunt

Recommended Posts

Last weekend I had the opportunity to collect in a quarry in southern Wisconsin. It appeared to cut through the Upper Ordovician Platteville, Decorah, and Galena Formations, although only the Platteville rocks were accessible. It was not the most productive trip but it was a new spot for me and I had a good time.

 

Here's a site shot plus a couple photos of large hash plates I did not collect.

The quarry was swarming with these baby frogs – I easily saw several hundred.

Here are the finds I kept.

 

Eoleperditia fabulites - giant ostracods

A large cephalopod fragment (probably Endoceras) coated with pyrite crystals

A nice slab of mollusks, including a very nice example of the curved cephalopod Beloitoceras

Cool finds. It’s always nice to find a new spot. :)

Very nice fossils. Are those gastropods Maclurites?

Probably something more like Lophospira.
