Hello all, I found this during the summer. It is from the Mississippian (Visean - Asbian/Brigantian) limestone of the Aran Islands off the west coast of Ireland. It is 2cm along the long axis. I Couldn't extract it so this is the only picture. Would love to hear your thoughts.

Can anyone tell me whether or not this is a type of coral? I found it in my yard yesterday. (Middle Tennessee, Mississippian, St. Louis Limestone & Warsaw Limestone)

This is another fossil which I would like to have identified. Can anyone tell me what the area circled in red would be? The rock is from my yard in middle Tennessee. (Mississippian, St. Louis Limestone & Warsaw Limestone)

I’m hoping someone will identify these fossils for me. I received a macro lens for my iPhone, and have been noticing a lot of tiny fossils on the rocks around my yard (Middle Tennessee, Mississippian, St. Louis Limestone & Warsaw Limestone). In the second photo, I have zoomed in on the object which has caught my eye. There are several like it on the rock. Can anyone tell me what it is?

Have very little experience with crinoids. I have these as Agassizocrinus cups. Can anyone confirm or correct? Upper Mississippian (Chesterian), Monteagle Fm., Huntsville, AL Scale in mm.
-
I picked this up Wed. I thought this was a crinoid. After cleaning not so sure about it being a crinoid. Arms are unsegmented and no pinnule are present. Rather these are very fine needles. It is from the Woodhurst Member of the Lodge Pole Formation, Madison Group Limestones. This rock is calcareous mudstone.

I found several rocks/fossils in the creek bordering my property in middle Tennessee today. (Mississippian, St. Louis Limestone and Warsaw Limestone) My favorite is a little one which has a few tiny fossils in it. I am particularly hoping to have the area circled in red in one of the pictures identified.

Hello, I’ve been trying to learn to identify the various bits and pieces on hash plates from my yard in middle Tennessee. I’m wondering if this one has a few trilo-bits in it. If not, can anyone tell me what they are?

Hello! I would love to have more info about this interesting fish bit that a paleontologist friend and I found a couple of months ago near Jackson, MI, in a glacial dump of Marshall sandstone. This little cobble was already broken as it appears, and we couldn't locate any other pieces of it. We're certain it's bone, and that it most likely came from the pectoral girdle (or pectoral spine area) of a bony fish. I looked through the list of Mississippian material found in MI from the Geology of Michigan, and noticed that while it describes lots of Chondrichthyes found in early Mississippian rock, no Osteichthyes from the Mississippian are recorded in that book. The closest match my friend suggested was Psarolepis / Andreolepis ( https://www.nature.com/articles/17594 ), but if this is the Marshall sandstone as we are sure it is, he says those genera would be far too old. Any thoughts would be welcome! (P.S. The second photo is a stereophoto.) Thanks, Lisa

I took my 4 year old Son geode and fossil hunting near the Missouri, Iowa, Illinois borders last weekend. We had a blast and found a lot of cool stuff. I found this calyx in the Warsaw formation which is Mississippian. It's obviously not done being prepped, but i figured there might be enough showing to get your opinions. It's actually been quite a challenging prep and may take some time to finish. I was thinking a possible Agaricocrinus sp., but it doesn't quite fit the bill. I can't find anything that looks identical. Any help is appreciated. @crinus @Crinoid Queen you guys still around? As found Some prep

I had posted this piece in General Fossil Discussion area since it had my first trilobite on it. Someone message me saying that they thought it may be an echinoderm. The person said “that looks like an echinoderm ("calcichordate")fragment. Possibly the M1-M4 of a stylophoran(marginale elements)” I thought it was a form of bryozoan. However, I do not know the Mississippian or any Carboniferous fossils very well. So I’m willing to admit complete ignorance. Can anyone ID it and educate me as what it is? I found it in Siloam Springs, Arkansas in an area which Mancos identified as the Pitkin Limestone, which is Mississippian. ROCKD ID’d the area as St. Joe’s limestone. This is the item in question. I can’t say that I have seen segmented Bryozoa. The segments aren’t uniform in size. Although, I’m not sure if the segments are endemic or an artifact of being broken. I believe they are breaks. It is about 1.25 inches long and 7 mm wide. Just a slightly zoomed in pic of the same thing. A pic of the end. This is is a pic of the back side of the other side of the plate and other end of it, where there is a cross section honeycomb looking view. Your thoughts and comments would would be greatly appreciated. Kim

Well, I found my very first trilobite!!! I just had to share my excitement with people who can appreciate hunting for something elusive and then finally finding it. With the family I get a polite “Oh, that’s nice.” I can actually tell it’s a trilobite. I’m pretty sure I’ve found pieces of others in the past, but they were so mangled it’s hard for me to be certain what I have. Anyway, I’m not sure if it is whole or not. I am still cleaning it up. Funny thing is I found it in my own home town of Siloam Springs, Arkansas of all places where I lived while in high school. My family still lives there. It was only about 1/2 mile from my parent’s house. Crazy. I found it on a micro hash plate of sorts next to Bryozoa that I had picked up from a new home construction site. I don’t know about anyone else, but hunting in the middle of a nice quiet little neighborhood feels a bit like dumpster diving. People watch and give you odd looks. I was looking at the Bryozoa with 10x magnification when I found the little trilobite. I absolutely was not expecting that. It’s so tiny I can barely see it with the 10x. LOL But hey a first trilobite is a first trilobite even if I can’t take pics of it and show it to anyone. It seems like the counter equivalent of a tall fish tale only it’s a microscopic trilobite tale. “It was this big/tiny . . .” I think there may be 2 others on the plate as well, but not quite as small. Not that you can see it, but it is a little white speck inside the red circle below. The Bryozoa thing is maybe 1.25 inches long and 7 mm wide. The little trilobite isn’t even 1 mm long. All I can see is the tale end. There are crinoid segments all over this piece too that are also microscopic. Some less than 1 mm. I found it in NW Arkansas in the Pitkin Limestone, St. Joe member possibly, which is Mississippian. The Bryozoan piece is actually much prettier than the pics portrays it to be. It’s all sparkly. It’s crystalized.

I found this rock about 20 years ago while hiking a piece of property I was considering buying, which was perched on a high bluff over looking the Illinois River. I picked it up because of the beautiful druzy crystals on it. I have been cleaning quartz crystals this week, which I found a few weeks ago near Hot Springs, AR. I was using Iron out to remove the iron stains. Anyway, I have kept this rock in my kitchen window so it could catch the sunlight and sparkle for me all these years. It is not the finest home decor, but definitely my style. I picked it up today to see if it had any iron stains on it that might need to be removed. As I was looking at it something in the chert caught my eye! I’ve had this rock all these years, but never realized, to my great delight (squeal!!!), there were fossils in it until today. That just makes it all the more special and cool. The formation there is Keokuk and Reed, which is Mississippian. I think these may be Bryozoa, but I’m not certain. I’m not sure I’ve ever hunted a Mississippian formation and found much besides crinoid pieces. Note the little rice grain size/shape dark spots on the top right side. I saw them and began to wonder if they were fossils. I turned the rock around to look at all sides and saw these rice grain size and shapes that were clustered together. See top center just below the crystal. These look flat, but in the next pic they have more dimension. Rice grain size and shape center of pic. The bottom of the rock. Note bottom center it almost looks like a plant leaf of sorts, but I assume Bryozoa. I have not found many fossils in the area. I found a couple crinoid fragments on the nearby land that I ended up buying instead. So, I’m pretty sure these are marine fossils. A few miles away to the east in Arkansas, in the Boone Formation, I found 3 Spirifers and abundant crinoid stalk fragments. Can anyone confirm that these are Bryozoa and if so what type they may be? Thank you in advance for your comments and input. Kim

Had two weeks off from school, so I thought I would poke around a bit at a few of the spots I frequent. It was way too hot to stay for any length of time but I did come away with a few good 'bits and bob's' (sorry, been watching a lot of videos of folk from the UK fossilin'.) Firstly, at the Pennington Formation I found what i believed at the time to be a beat up Petalodus tooth. I set it aside when i got home and didnt touch it until returning from my second trip. i thought maybe I could clean it up a bit, but soon noticed it had striations going from the root up. petalodus doesn't have those so i decided to have a go at it () with my airscribe. This is basically what it looked like, with matrix covering the top portion. With a little scribing I uncovered a blunt cusplet which is when I started getting excited! After many hours of scribe work here is what Ive uncovered: A very large Cladodus-type tooth! The biggest Ive found intact! Its only missing a couple of cusplets. I had to stabilize it with super glue as the root was full of cracks. i'll take better pics this weekend. Needless to say I was chuffed! I'll post the results (and the heart-break) from the trips I took over vacation this weekend so stay tuned!

Any ideas on the identity of this? (Sorry, this was a field photo, so no scale) Mississippian: Osagean - Elsey Fm. Silex, MO

I found this long exterior mold fossil in Mississippian Redwall Formation chert from Gila County, Arizona. I think that it might be the central support for an Archimedes sp. bryozoan. Two sources say that they have not been reported from the Redwall Formation even though they are reported from other Mississippian formations in Arizona. What do members think the fossil might be? @Arizona Chris

A near complete, partly enrolled Paladin sp. found a couple of days ago, lying in three pieces in a pile of disintegrating mudstone. Brigantian stage (Mississippian), N.E. England, UK. I spent ages unsuccessfully looking for the missing bit but never mind, it's still the nearest to a whole one I've found for about four years - decent Carboniferous trilobites are generally hard to come by though moulted bits are quite common at the site. This stuff falls apart when wet and another spell of rain would have completely destroyed it. Apart from gluing, no prepping was needed. 1.5cm long

I found this while breaking fossil rocks looking for some interesting subjects and came across this, most if not all fossils in this area (Ohio) are from the Mississippian period where I’m digging. Please give any info on this I have never seen anything like it.

Invertebrate(?) conical spines in Mississippian (Meramecian) Salem Limestone
pefty posted a topic in Fossil ID
Could use some help on these 0.5cm - 1cm invertebrate(?) conical spines in the well known Salem Limestone, a marine limestone of the American Midcontinent. They appear to be solid calcite but do not quite match up with the shapes of crinoid spines and echinoid spines that I know from the Mississippian. I have looked at umpteen Salem Limestone samples but have seen these spines at only one small locality. Any insights appreciated! but please provide your reasoning or evidence.

Its been a long time since Ive posted any find on here, so I thought Id show some of what I collected during this past winter. I took a trip to the Silurian of Tennessee to collect with a friend and did pretty good. This was my first time collecting Silurian fossils. These are from the Brownsport Group. I'll start with the sponges Astraeospongia meniscus a fairly common sponge, I collected several. Next up is a neat little Brachiopod. Machaeraria sp. And now enchinoderms. Calyx of the crinoid Lampterocrinus tennesseensis Another first for me...a cystoid! Caryocrinites ornatus and another! A nice blastoid - Troosticrinus reinwardi Heres a shot showing the complete ones I found. The two large objects on the top left are sponges. The items with the branches may be bryozoans (one has a stem wrapped around it.) The crinoid cups to the right are Parapisocrinus sp. And the item by the penny is a tiny Leptaena sp. brachiopod (another first!) And now for my sole arthropod find. The surface is very rough, but it seems there is a mold under that. I may try to uncover it. The pygidium is folded down ninety degrees to the rest of it. Not sure as to id at this point. But it seems to be mostly there. I forgot to photograph the corals I found on this trip so I will add those this weekend. About a month ago I found myself very early for work so I decided to stop at the Pennington formation ( Upper Mississippian) for a quick hunt. I didnt keep much but I did snag this partial Deltodus affinis tooth. Thats all for now, thanks for looking.
