Peat Burns Posted March 31, 2017 Share Posted March 31, 2017 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?) 2 Link to comment Share on other sites More sharing options...

Peat Burns Posted March 31, 2017 Author Share Posted March 31, 2017 Petrodus sp. (?) denticles (Chondrichthyes: Symmoriiformes). Not sure if the upper one is also referrable to Petrodus... (?) That's all folks. Thanks for looking! 1 Link to comment Share on other sites More sharing options...

Uncle Siphuncle Posted March 31, 2017 Share Posted March 31, 2017 Love that site. It is the only place I've hunted Mississippian. The fauna is diverse and has added a cool dimension to my collection. You did quite well, as it is a popular site. Love the Poecilodus. In my 3 trips there, I've been fortunate to pick up 2. If you are a prepper with air scribe experience, be advised that I've found the Poecilodus to be preppable with a steady hand. The matrix seems eager enough to separate from the enamel to afford exposure of the entire tooth. I can send you pics of my prepped ones if you like for reference while you prep. Always pays to accurately anticipate hidden features. It seemed to me that the trilobites weren't quite as amenable to letting go of the matrix, so when I finally found a whole Kaskia with its head buried, I left it as is and simply trimmed the matrix down. I've taken 3 or 4 crinoid crowns there too, one quite spectacular, Plaxocrinus methinks. 2 Grüße, Daniel A. Wöhr aus Südtexas "To the motivated go the spoils."

This was only my second trip to that site, so I'm still learning the logistics, secrets, and fossil assemblage. @Uncle Siphuncle I have prepped I couple shark teeth from Sulphur and, like you, have found them to separate well (although sometimes too well, as I have had them pop off the matrix entirely and had to glue them back on ). I'd much enjoy seeing your Poecilodus for reference before I work on this one. I agree about the Kaskia being "sticky". I used a pin vice to whittle my way down to the exoskeleton prior to air abrasion, and it's laborious and hard on the wrist / hand... Last time I was at Sulphur, I found a crinoid crown. I'll try to remember to share it to see if you can help me put a name on it. With kind regards, Link to comment Share on other sites More sharing options...
