While searching for crinoids a few days ago, I found two items which I thought were especially interesting. Can anyone identify them for me? (Mississippian/Tuscumbia Limestone)
-
I was given some Archimedes bryozoans and I was told they are from a Mississippian exposure somewhere in Alabama. I'm afraid that's all I know so far. They have a feature I'm not used to seeing. The only ones I have found consist of just the central axis support, or "screw." These do not show that part at all but they have just the outer edge of the fenestrated portion exposed the whole way around the specimen like this. Using only hand tools I started trying to expose the fronds to see if that is even possible and had some pretty good results. I will try to either saw or sand one of them down to see if I can expose the central axis and maybe prepare the other side like I'm doing this one. I can probably manage that part okay but exposing the edges is very tedious. I may have someone with air abrasion tools see if they can't do a better job than what I am managing. @Ptychodus04 ? Want to trade some labor for a couple of these?

Greetings, all! I am currently writing a thesis involving fossils from the Burlington Limestone near its type section along the Illinois/Iowa border. To demonstrate the diversity of the crinoidal remains from the limestone (over 400 species have been described from the Burlington alone!), I am looking for photographs of articulated crinoids. Do any of you have any that you would like to let me include in my thesis? If possible, I would like high-res images of crinoids identified to genus or species with a scale bar/ruler present in the image as well as the collection/locality info. I can't guarantee that I will use every image posted, but if I use your image, then I will acknowledge you in my acknowledgements and give you credit for the image. Thank you for your time & assistance! -Elasmohunter

My husband found this while we were fossil hunting today. I’m hoping someone can identify it for me. The area is Mississippian/Tuscumbia Limestone.

My husband and I decided to go on a quick fossil hunt this morning. The area is Mississippian/Tuscumbia Limestone. I was delighted to find this small, square chunk of rock right away. It almost appears to be a shadow box for the lovely little fossil embedded within it. I am wondering if it is a tentaculite?

Mississippian Road Cuts in Anna and Vienna, Illinois
Nimravis posted a topic in Fossil Hunting Trips
I got of Chicago a couple hours before the snow came today- This has been such a bad winter / spring in Chicago - last weekend it was 80. I digressed, back to fossils. Today with a nice temperature of 72 degrees, I did about 3 hours of collecting at the Anna and Vienna road cuts in southern Illinois. These Mississippian road cuts are conveniently located off of I-57 and 146 (Anna) and I-24 and 146 (Vienna). I first stopped at Anna- you can collect on each side of the road, but like many sites, you need to look closely to find fossils. Here are a couple pictures of how the fossils were found. Here are a couple pictures of the fossils that I found at Anna. Pentremities spicatus Blastoids/ I do not have my scale cube handy, so I used a standard pen. Horn Coral- Archimedes screw- Crinoid stems- (I only pick up these to show that they are present) Brachiopods- Vienna finds will be next-

I came across this nice little Mississippian shark or shark-like fish tooth. The information provided by the seller is Orodus sp. St. Louis limestone Formation. Cloverdale Quarry, Cloverdale, Indiana. my question to the Paleozoic shark experts on the forum would be is this an Orodus tooth? I am far from an expert but this looks a bit like a Caseodus to me. I know Orodus teeth have several forms but this did not look like one to me. Any information or help would be awesome !!

I’m hoping someone can tell me which type of fossil(s) are in this? Bryozoan? Brachiopods? It looks different from the brachiopods I found in Tennessee. I was inordinately pleased to find this little rock while my husband was building our deck, as this is the first fossil I have found in my yard since our move to Alabama. Woo-Hoo!

Hey everyone, long time no see! Last week, my historical geology class went on a field trip and did a little fossil collecting, so naturally I've had the fever ever since. A couple of days later I decided to hit a nearby roadcut and do some nosing around. After a few hours I had collected some very nice echinoderm material (including a nice Taxocrinus crown), some of which I am not totally familiar with. What I thought to be my most unusual find was this weirdo little blastoid. The first thing that struck me is the rust color, I've only seen this in my Floraville blastoids, and those are just slightly rust-colored, not covered head to toe like this little guy. You may not be able to see this in the photos, but there appear to be some pseudofossil markings on one side. Another strange characteristic is what I'm going to call the arrangement of the plates, could it be that this thing didn't get to 'close itself up' all the way before it was buried? (I do not study biology or paleontology so please stop wincing) If not, I'm wondering if I found one of the less common species of what I assume to be Pentremites. Of all the blastoids I've found, this one is probably the most unique, if someone could help me ID this thing it would be greatly appreciated! If additional photos are needed, I will gladly provide them. Thanks, Matt P.S. I apologize for the poor lighting in the photos (and for the lack of scale!), it's very hard to get a good picture in my half-subterranean apartment that only gets direct sunlight early in the morning. P.S.S. Hats off if you picked up on the Twilight Zone references.

This is a plate of Productus brachiopods with spines collected from marine sedimentary brown-red clay shale, which sits on a bed of breccia limestone. Location is slope above rest-stop on east side of Highway 89 N about two miles north of Riceville Rd. in central Montana. Was collected on Jan 21,2019. Prep work was done by collector David C. Powers.

Hey all, after a long work-related hiatus I have found myself back in a part of West Virginia that has fossils! Yesterday I found a long bed of unknown material exposed on a ridge in northern Monroe County with a lot of fossils in it. I don't know the formation, but from what I could find out this area should be Mississippian. Am I right in thinking the attached photo is a bryozoa? Also, if I collect more samples, take photos of the outcrop, and give a good description of the material might it be possible to identify the formation? Thanks

Fossils on Wheels received another generous donation to our education programs this week. TFF member @Herb sent us a box of super cool invertebrates. He sent us a diversity of fossils from the Southern US that cover a wide range of eras. These fossils will be given to students in fossil starter kits and used in hands-on activities. Herb's donation is also awesome because this pushes me to learning a lot more about invertebrate fossils. One of the best parts of teaching kids about natural history through fossil exploration is that I get to learn a lot. Good teachers learn and challenge themselves so they can challenge their students. I do not have a lot of knowledge about these types of animals but I am so excited to start learning. Among the fossils we received were- Mississippian Corals and Brachiopods from Kentucky, Crinoid stems and Silurian sponges from Tennessee, Cretaceous Gastropods from Texas, and Eocene Bivalves from Alabama. Thank you Herb for a generous donation that will get put to good use

Stethacanthus + other shark teeth for trade
fossilsonwheels posted a topic in Member-to-Member Fossil Trades
We completed our first trade on the fossil forum recently and it was awesome. We got a great fossil and a cool new friend. I am putting up one of my Stethacanthus altonensis teeth because I want to bulk up our shark education program just a bit. It is really the only tooth we could trade that has much appeal. Here are the details on the teeth we have to offer. I actually think this one of our anvil shark teeth. This one is smaller but has the tip intact. The details Stethacanthus altonesis Delaware Creek Member-Caney Shale Formation Mississippian-Meremacian Pontotoc County, Oklahoma We can also offer some trade filler too but none of it rare or anything. PM if you want pictures of these teeth. 2 Isurus planus teeth from Sharktooth Hill Miocene 1 Ptychodus whippeli from Texas. i have no other information about the tooth. 1 Cretaceous Shark indet tooth from New Jersey ( I think). Scapnorhynchus was the leading opinion when it put it on the TFF for ID. It was not a unanimous opinion though. We are looking for specific things to fill in our education presentation about sharks. Astercanthus teeth and spine. Any Hybodont shark would work but in a perfect world we find an Astercanthus sp. Caseodus tooth Campodus tooth Cardabiodon tooth Feel free to say hello if you are interested. In pic 3, the trade tooth is on the right.

This is a new one for me. A neat little button-like horn coral: Dipterophyllum glans from the Middle Mississippian Burlington Fm. of Iowa. Didn't know which forum to share this, so I thought I'd drop it off here for posterity (scale in mm)

My son and I are doing our first Shark Adaptation classroom education program in March. We are using fossils from across the timeline of sharks to explain to the students how sharks have managed to stick around this planet for some 430 or so million years. I am very proud of the relatively small fossil shark collection we have. The kids will get to see and in a lot of cases handle some fossils from badass sharks. I thought it would be fun to put some of that collection and bits of the information we present. Eventually I will include the art work my son is producing. He is 5 months away from graduating high school so I limit his time on this art while he works his final art projects for school. The first shark we cover is also one of the most fun for me. The Cladodont sharks are pretty cool and as I recently learned present a perfect opportunity to utilize them in two different spots in our presentation. They start off the program because of Cladoselache. They were not the first shark but they are the basic design for sharks that would be recognizable to 3rd and 4th grade students. They had body type that modern sharks use and they had some fearsome looking teeth. They may be really small teeth but they were deadly if you were a small fish. Science thought these little sharks went extinct during the Great Dying but in 2013 that theory was proven wrong. There were Cladodont teeth found in France that dated to 120 million years ago. They survived the Permian by moving to deeper waters. The small shallow water sharks apparently became very successful as smaller deep water sharks. The physical adaptations are important but the adaptive behavior of sharks is a huge part of how sharks have survived for so long. We only get a few minutes on each shark so that is the basic stuff we will tell the kiddos. Here are the teeth. Pic 1- the unidentified Cladodont tooth. I love this tooth. It is one of my favorites. Under the micro eye, it looks so freaking cool. It could be a Symmorium. It could be something else. It might even be something new. It is from Russia and dated to 320 million years. This will get donated for research at some point. Pic 2- Cladodus belifer. A Mississippian tooth from Biggsville Quarry in Illinois.

I decided to take the day off of work today because it was supposed to be in the mid 40's and I figured I could whack open some Mazon Creek concretions. I was very nice out, but I figured that my time would be better spent cutting down matrix on a number of pieces that I collected recently from 3 different time periods (Pennsylvanian, Mississippian and Ordovician). I did not get everything cut down, but it was a good start, here is the aftermath. Pennsylvanian- Sometimes things just pop out of the matrix like the two beauties Ordovician- Mississippian-

I have a strophomenata brachiopod with small circles and what look like puncture holes in center of circles. What may have caused these?
-
I collected this Leptaena brachiopod from the red brown mudstone resting three feet above the top of the first out crop of breccia limestone. The location is above the rest-stop on highway 89 S before Riceville Rd. The formation is the lower part of the Kibbey. Leptaena Brachiopods dominate along with three types of bryozoa and crinoids. Also found clams and a part of a plant fossil. The setting was once a lagoon.

Hopefully this will be quick and easy for those who have the knowledge. I was meandering in the hills and came across some horn corals. I am used to calling the smaller one on the left a horn coral. I am presuming the one on the right also a horn coral. Would someone kindly provide sufficient naming to each so I can do some offline research and reading? Apologies for fuzzy pic. Camera seemed to only want to focus on the backdrop material.

A daylong venture into the back canyons of the Sacramento Mountains to look for minerals and fossils. From the trailhead & back was just under 9 miles and lots of rock scrambling through Ordovician-Pennsylvanian formations. A dryfall requiring a climb around Overhang with rippled sandstone floor having iron concretions A view back down hill partway to summit Horn corals Maybe coral?

Goniodonts - strange echinozoan teeth from the Carboniferous
TqB posted a topic in Member Collections
I was surprised to see this specimen for auction and pleased to win it. It's Anguloserra thomasi, a rare tooth from an ophiocistioid echinoderm and comes from the same locality as the holotype described here (abstract only): Haude & Langenstrassen 1976. I've been interested in these since finding three similar specimens in the UK that took a while to identify - shown in the next post. It's preserved as an impression - most material in this matrix is decalcified. Carboniferous, upper Mississippian, Culm beds (equivalent of Brigantian and Arnsbergian beds in UK), Aprath, Germany. Scale in mm. Here's the holotype from the linked paper (a latex cast):

I have jokingly told people there are literally trillions of crinoid column fragments in this area but I have only found bits and pieces of the crowns. On Christmas Day, while hiking with my wife, I found what I think may be a potential crown in a rock having lots of column fragments. Thus, my request for some substantiation of the possibility. If this is a crown, I will go back to try and field extract just the portion of this rock having the specimen. I think it would be a good one as a 1st experience for exposing/prepping to reveal more of the fossil. The width of the specimen is just at 2"
