Raggedy Man Posted April 19, 2015 Share Posted April 19, 2015 I visited Vulcan quarry today with ESCONI and found an interesting specimen. A class was also visiting the quarry from the University of Illinois at Chicago. Their instructor suggested it might be a burrow, but he was unsure because he has never seen one like this from that quarry or anywhere else. We had even toyed with the notion of this being a cephalopod, but as you can see it lacks the septum rings.

fossilized6s Posted April 19, 2015 Share Posted April 19, 2015 Warthog tusk. Duh.... Lol Im in the "clueless" group. Sorry Paul. So how was it? Did you find anything else? ~Charlie~ "There are those that look at things the way they are, and ask why.....i dream of things that never were, and ask why not?" ~RFK ->Get your Mosasaur print ->How to spot a fake Trilobite ->How to identify a CONCRETION from a DINOSAUR EGG Link to comment Share on other sites More sharing options...
Raggedy Man Posted April 19, 2015 Author Share Posted April 19, 2015 (edited) ROFL that was the joke being tossed around. I found a big cephalopod fragment and some nice plates, but no trilobites. I did however hit the jack pot in St. Paul, Indiana March 27 with ESCONI. Ill be posting those photos soon. All though not prepped, the trilobite plate I found is exciting. In all I found around 7 trilobites and a complete crinoid with intact arms with a nice sized gastropod in the same matrix. Ill be prepping those soon and post the finished product. Over all the trip to Vulcan to enjoyable and fun. Edited April 19, 2015 by Raggedy Man ...I'm back. Link to comment Share on other sites More sharing options...

fossilexpress Posted April 22, 2015 Share Posted April 22, 2015 (edited) An answer (mostly from Pete Wagner (Smithsonian) but also Seth Finnegan, John Catalani, and Steve Holland): this is snail, probably Lytospira or a close relative. Clues include the septa and the ridge on top where the selenizone would have been. Thanks for showing this to us - Roy Plotnick - UIC Edited April 22, 2015 by fossilexpress 2 Link to comment Share on other sites More sharing options...
Auspex Posted April 22, 2015 Share Posted April 22, 2015 I have to remark on the large size of this specimen (4+" as exposed): isn't this unusually large for Lytospira?

Raggedy Man Posted April 22, 2015 Author Share Posted April 22, 2015 Thanks Mr. Plotnick. I had no idea the paleo meeting was that night or I would have stayed out there. I'll still bring it to the next meeting. I'm sure John would still like to see it. ...I'm back. Link to comment Share on other sites More sharing options...

Raggedy Man Posted April 22, 2015 Author Share Posted April 22, 2015 (edited) Ipieterick, were you there Saturday? THAT crinoid is SWEET. Paul Edited April 22, 2015 by Raggedy Man 1 ...I'm back. Link to comment Share on other sites More sharing options...
fossilexpress Posted April 23, 2015 Share Posted April 23, 2015 Based on the lithology, I suspect the receptaculitid came from the lower part of the quarry, which is in the Galena. I have seen receptaculitids in the Galena elsewhere. BTW, my students went through their collections today in the lab. In addition to lots of brachiopods and bryozoa, crinoid fragments, and the occasional cephalopod, bivalve, and gastropod, there were three trilobites (Flexicalymene pieces), a cornulitid, and a tentaculitid. As to the Lytoceras, this was my first exposure to the genus, which is a pretty weird snail. Based on the images I have seen, they do get pretty big, although that specimen is a the upper end of size. - Roy Plotnick, UIC Link to comment Share on other sites More sharing options...

erose Posted May 12, 2015 Share Posted May 12, 2015 I believe post #9 is a jumbled frondose bryozoan.
