Hey fellow list members,

I am preparing a small field guide for a trip to the well known (by 
others, not me) road cut at I-64 and Indiana Route 37.  We are being 
lead there by one of our members who is in the geology department at 
Purdue.

So far he has been able to provide me with pretty good stratigraphic 
information but there seems to be little on the paleontology.  We 
know of several "faunal lists" that have been published (Horowitz, 
1979; and Kelly, 1984)  but have not been able to obtain copies of 
them.

The exposure is in the Indian Springs Shale Member of the Big Clifty 
Formation (Middle Chesterian epoch; Late Mississippian Period).

 From what I can gather, this is a site known for blastoids and other 
echinoderms. I also understand there are several corals and some 
other invertebrates as well as scrappy vertebrate material to be 
found.

So can anyone on this list provide me with a faunal list &/or 
description of the paleoenvironment?  A list of published references 
would also be useful. Also any basic collecting tips for the site 
would be helpful.

Thanks in advance,

--
