Hunting The St. Leon Road Cut, (4/5/14)

After visiting family in Ripley County, IN on Saturday, I had time to collect from the road cut north of St. Leon for the first time. This was also my first time hunting a road cut so I didn't know what to expect. About 5 minutes in, I found a crinoid stem in one of the rocks that was a couple inches long and only about an eighth of an inch wide. Unfortunately, it got misplaced and left behind. Rafinesquina and rynchotrema were plentiful as well as bryozoan fragments. After 2 hours and not much luck, a college group arrived and they also didn't find much. Many of them were looking for trilobites and were unsuccessful. Another hour had passed without much to show and I had to leave as it's nearly a 2 hour drive back to Indianapolis. Before I left, I filled a small container with some of the smaller rocks to sift through when I got home. Overall, I had a good time and can't wait to go back. My best finds of the day were a bivalve which I've yet to identify, a fragment I believe is from an orthocone, and a fossil that has puzzled me as to what it is. Pictures included are those of the mystery fossil and more pictures are to come.

Images left to right:

- A bryozoan fragment and 3 small brachiopods

- A 1/2" horn coral and another small brachiopod

- A brachiopod still in the rock

- The bivalve

- Bryozoan encrusted on a brachiopod

- 2 rynchotrema

- The next four pictures are of the possible orthocone

- 2 gastropods

Since I'm still new to fossils I don't know many names so help identifying my finds would be greatly appreciated.

You did good for your first time. This is a great site. I love collecting there. The pictures are quite small to make out the first item. It does at first glance look like some crinoid arms. Many of the trilobites i find are small. If you want any literature for that particular site send me a pm. Also strata.uga.edu is a good resource.

Try http://drydredgers.org

the Drydredgers spend a lot of time at St.Leon, their site has ID's for most of the sites fossils. It's also in our Links section.

The small brachs in the first picture are probably Zygospira and the clam is probably Ambonychia.

I forgot to mention this but I think the unknown fossil is the brachioles of Glyptocystitid Rhombiferans. The Dry Dredgers website said that thecas are common finds but not the brachioles.
