Hi! This teacher is spending the last day of Fall Break Christmas shopping - fossils for my students! Found a few beauties for teacher, too... I think this may be part of a trilobite... thoughts? More pics in comments of other mystery finds as I find them! Thanks in advance!

Here's a crinoid I found the other day in the Menard Limestone (Chesterian series). I'm not so sure of what genus it may belong to.

Hi all, I was going to wait to post this trip report after I had time to wade through the brachiopod literature and put a name on the brachiopods. But, if I do that, this will be a history report (if some of you are inclined to save me some time and know the identity, please chime in ). This is a trip taken to Sulphur, IN, on March 16, 2017. The fossils come from the Big Clifty Formation (sensu lato) and some specifically from the Indian Springs Shale member of the Big Clifty Formation. The cut exposes Late Mississippian: Early and Middle Chesterian deposits. I forgot to take photos of the exposure, but there are plenty on the web. Here are the fruits of this particular trip: Zaphrentites spinulosa (Cnidaria: Anthozoa: Rugosa) Connularia sp. fragment (Incertae sedis; Cnidaria: Scyphozoa?)

Since I was on spring break and finally had a Saturday off, I decided to drive a few hours south to a couple of the best Mississippian exposures in my area. I've been to these spots in the past and have always had a pretty decent haul. Here are some of my finds from my most recent trip, enjoy! Blastoids (complete with in situ shots) Brachiopods
