Indy Posted August 25, 2011 Share Posted August 25, 2011 Trepospira minima Rare Pennsylvanian Snail ?? Middle Pennsylvanian Series - Desmoinesian Stage Marmaton Group - Altamont Formation Lake Neosho Shale Member - St. Louis, Missouri Trepospira minima (left) and Trepospira depressa Trepospira sp. is a small COMMON Pennsylvanian gastropod and most of us who hunt the Pennsylvanian have several in our collections. the shell is smooth but ornamented by nodules between the whorls. Trepospira is known from the Devonian to the Pennsylvanian. Scale: 1 CM Page on my Pennsylvanian website: Click Here Over the years (from time to time) while searching the Net I come across links pointing back to the above page...and it keeps reminding me how ODD it is that this image of Trepospira minima is the ONLY image I have ever seen showcased on the Net. I would be very interested in a discussion on the subject including viewing images of Trepospira minima found by other collectors. Doesn't have to be identified as minima, however, images of Trepospira with the same or similar ornamented "fluted" nodules. Possibly there are those who have found Trepospira minima and wondered about the unusual nodules or identified under a different name?

piranha Posted August 25, 2011 Share Posted August 25, 2011 Haha... not sure on these as I am a slow-poke when it comes to snails. Fabulous fossils Barry! Link to comment Share on other sites More sharing options...
Indy Posted August 25, 2011 Author Share Posted August 25, 2011 What I have identified as Trepospira minima, has always raised a lot of questions. The locality is known for its snails and this is the only specimen that I have found there (I have been collecting this locality for over 15 years) Worn out 2 pair of field boots and 3 sets of knee pads. Only 1 Trepospira minima Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
piranha Posted August 25, 2011 Share Posted August 25, 2011 Barry, have you checked the Paleobiology Database? There are a few occurrences recorded in Missouri and a reference to a paper from 1961 that might be useful for you. LINK Link to comment Share on other sites More sharing options...
Indy Posted August 25, 2011 Author Share Posted August 25, 2011 Barry, have you checked the Paleobiology Database? There are a few occurrences recorded in Missouri and a reference to a paper from 1961 that might be useful for you. LINK Thanks for the link...On the web page, I have the reference for the ID Desmoinesian Brachiopoda and Mollusca from Southwest Missouri However, really never dug too much deeper...following the links, there is some excellent information...Thanks Not every picture of every fossil is archived on the Net. However, over the years I just assumed 1 other web page would have popped up with an image...Who knows...Maybe the minima found home and relatives never moved out of state? :laughing on the floor 24: Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Roz Posted August 25, 2011 Share Posted August 25, 2011 I have only found the Trepospira depressa in hunting Pennsylvanian sites so far. This weekend I plan on going through my fossils from that age and make sure I don't have one that I just didn't notice. Not likely but you never know.. The book I use frequently for finds of that age is Pennsylvanian Fossils Of North Texas and it mentions Trepospira and has two pics both of the depressa.. No other ones shown.. Excellent find and great pics too! Welcome to the forum! Link to comment Share on other sites More sharing options...

fossil dude Posted August 26, 2011 Share Posted August 26, 2011 im not sure you want to hear this and am not bragging but in s/e okla i have found over one hundred trepospiras in one day, one of the sites near holdenville ok. three fourths of all the fossils i find are trepospiras, at other sites near there they are rare, why so many in one place i don't know! if i can figure out how to upload my pics i will send to you.

No you are fine fossil dude. Its always great to exchange information like this. Now, according to some of the stats I have compiled there are pennsyvannian sites that I have studied, there has been an increase of approx 4% of Trepospira in relation to max found of specimens in a given day (previous number was 2%)however in regards to the calculation I used both T.deppressa and Trepospira sp. But T.deppressa is a common class 2. I done think we need to make a Trepospira show off.

Trepospira depressa is common at the posted locality and have collected (kept that I found) hundreds and could collect 100 in a day also.

Good to see reference to Oklahoma as well as Texas. Most fossil hunters are not familiar with Trepospira minima and many when finding Trepospira do not closely examine each for something they haven't seen before. Since you have found hundreds of Trepospira...It is possible that you have in your collection at least 1 Trepospira minima. If you find one, please reply with a picture. Thank you very much for your reply...Most appreciated Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
Bullsnake Posted August 26, 2011 Share Posted August 26, 2011 Can these be found in Upper Pennsylvanian? The only gastropods I've found are internal moulds, and I've only tentatively id'd one as Pharkidonotus. Steve Link to comment Share on other sites More sharing options...
Indy Posted August 26, 2011 Author Share Posted August 26, 2011 Bob Shaha from Claremore, OK used to bring tons of marine Pennsylvanian fossils to MAPS every year. I used to love to sit with him and his wife and share information and compare fossils found in St Louis with the fossils he found in OK Bob and his wife no long attend the show and they are sincerely missed. I guess the subject of Trepospira minima never came up in conversation. Guarantee if he found them he would have a wonderful associated story on the subject.

Texas-Tunnel Rat Posted August 26, 2011 Share Posted August 26, 2011 very cool Indy! do you happen to have those maps or where someone could find them.

I am always looking foward to keep going on my Carboniferious studies, compairing parts of TX with other parts. I was referring to talking with Bob at the MAPS fossil show in Macomb, IL and not referring to locality maps. Now that you brought up the subject of maps...I wish years ago, I made note of the localities he hunted in OK. Bob always told me if I get to OK to drop by and he would take me fossil hunting. Bob always brought Killer Pennsylvanian fossils to the MAPS Show. Contacts are like hot fossiliferous localities which have been around for years. We take for granted they will be there next week. I remember one Mississippian locality that I hunted frequently for a number of years...Didn't hunt it for 6 months and went back one day and drove by it without even recognizing it because the exposure was GONE and in its place was a Walmart. :startle: Edited August 26, 2011 by Indy Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...

Shamalama Posted August 31, 2011 Share Posted August 31, 2011 Indy those are some nice snails you found! I love the gastropods from the Pennsylvanian of OK, TX. they are so well preserved and detailed. Thanks for the link to my blog post about the giant Straparollus too. I've wondered if it might be a different species but I can't find any solid info to say otherwise. -Dave __________________________________________________ Geologists on the whole are inconsistent drivers.

Ludwigia Posted August 31, 2011 Share Posted August 31, 2011 Hi Barry, I just noticed this post today. Although I'm not familiar with these formations or for that matter, your part of NA, I find the information and discussion very interesting and enlivening. Sorry I don't have a minima to show you. Wish I did by now. That's a great website also, by the way. Glad to have you actively with us here in the Forum. All the best, Roger Greetings from the Lake of Constance.

I've always been fascinated with this giant and KUDOS on your Excellent photography illustrating "fossils in hand" ONLY images of fossils "in hand" give instant recognition of true size and shape. Short story: Years ago a professional confirmed an ID of a horn coral on one of my pages (with a CM scale). Sometime later I added a few pictures to the web page illustrating the "fossil in hand" .... He IMMEDIATELY replied..."I had No Idea the coral was so Large" Flash from the Past (Show Us Your Fossils)MAPS Fossil Show Link to comment Share on other sites More sharing options...
