wshw1looked like wood. I will have to look up horsetail plant. The one marked tree fossil looked like a Lycopsids to me. There was lots of stigmaria and bryozoan present in the area as well. The one marked fossil2 I think is a stalactite. I found it with the one marked cavedebris in a pool inside a cave today.
Everything today came from the Snowball Quad in Searcy County Ar. The ones from the clay formation are from the Arkansas River Valley along the Illinois Bayou in Pope County, Ar.
Sorry Las Vegas Bob I'm losing it. Stigmaria and Lycopsids are one and the same basically. Now I can't remember what else there was in large amounts along with the bryozoan.
