Hello everyone, I recently purchased this plate of brachiopods and bryozoa from the Waldron Shale in Indiana. I received a label with it but to me, the IDs on there do not seem right, so I wanted to ask here for your opinions. Here is the whole piece: I'll start with the ones I think I have identified. First, the brachiopod on the left in these photos: I think this is a Dictyonella reticularia due to the overall shape and the surface ornamentation which looks close to the specimens I have seen in my research. This was the only species listed in a list of fauna I found from the Waldron shale although other sources have other species from this genus. Originally it was labeled as Meristina nitida. Next, the small pyritized shell: Originally this one was labeled Orthis hybrida, that did not look right to me at all, I did a bit of searching and am now wondering if this could be Resserella sp.? not sure which species though. And finally the ones I am most confused about, the multiple bumpy shells: I think it is pretty clear these are Atrypids, they were labeled Atrypa reticularis by the seller. I have many brachiopods from this genus and species but have never seen any with such prominent shell ornamentation. I tried digging though fauna lists and other resources but other than that species I haven't found much. Does anyone know what this one might be, and if my other IDs are accurate? Any help is greatly appreciated. Thank you for taking a look, Misha

Found in the basement of an abandoned home in South Bend, Indiana, surrounded by farm land. What could this be? (Photo taken ~10 years ago, apologizes for the less-than-great quality)

In the little bits of matrix I have from the Waldron Shale of the Illinois Basin of SW Indiana, I have recently found this specimen. I'm fairly sure it's a crinoid, may even be two or three in this piece, a sort of mini mortality plate. Anyone have any idea which genus of crinoid it could be please? A second calyx to the upper right of the first, perhaps? This looks like another calyx, located just under the first but aligned in the same direction :

I love this specimen. I though it might be Tentaculites at first, but I can find little reference to them in the Waldron Shale other than really old mentions of T. inornatus and T. niagarensis from the Rochester Shale of New York which is of about the same age and has many species that also occur in the Waldron. However, it may actually be a really weird bit of echinoderm stalk. It's very tiny and I'm not sure if it tapers or not as the matrix covers part of it and is stubbornly refusing to come off. It seems to be solid rather than hollow. Or maybe not. The shell may have come off a part of this to reveal calcite infilling of the interior? Any ideas, anyone?

I have found quite a lot of curved, calcite plates in my samples. Some are loose and others in the matrix from my Waldron Shale, S.W. Indiana samples. They are often quite plain and I was thinking athyrid, but the athyrids in the Waldron Shale seem to have rather thin shells and these are quite thick and chunky. I still think athyrid is most likely. Other, quite similar bits seem to have tubercles or spine bases on them. Trilobits? Echinoderm? Another lumpy one : Or be shaped like an echinoderm plate? The reverse : Any help greatly appreciated as always. Thank you looking! @Peat Burns Someone mentioned that you know a bit about the Waldron? Any input, please, Tony, old chap? Or the brachiopods from this formation, I'm drowning in the dark here.

A few years ago I picked up an old paleontological publication from a University of Chicago used book sale and one of the sites described looked interesting. I finally got around to visiting the site last week, a good 5+ hour drive. It was completely overgrown so had to hack my way to the exposure. Middle Mississippian rocks. After about three hours of careful work I came across some Griffithides skeletal elements buried in foraminifera matrix. I also found this nice calcite crystal that fluoresces pink under UV. The white crystals at the base phosphoresce for about 15 seconds. Found nearby was this turtle carapace. I'm not sure ,but I think it could be an Eastern box turtle shell.

Spent the day at the famous old cut in Sulphur, Indiana yesterday, and while I didn’t come away with a Mississippian shark tooth, I’m wondering if other parts of these animals preserved? This piece is shiny black like coal, about an inch long, is definitely fossilized, and was found in the Big Clifty formation. Anyone here an expert on Carboniferous sharks or has found anything similar?

Another mystery from the Waldron Shale of the Illinois Basin in Indiana. Any help or suggestions most gratefully received. The object appears to be hollow and sort of tubular. Scale is in mm. so it's pretty small.. Thank you.

Last Sunday I took the day to scout some former coal-mined land in western Indiana as well as revisit some sites I hadn’t been to in a few years. The mines at these sites were working the Springfield, Hymera, and Danville coals at various points in the mid-late 20th century. The land has been reclaimed to varying degrees, but I hoped that typical Mazon Creek-like fossil-bearing concretions could still be found, despite almost no information in the literature. Temperatures were a little chilly with the wind blowing as I arrived at the first site. There to greet me was a herd of cattle grazing on the property, including this friendly? individual. I looked at the ground as I walked along the road to the property and quickly saw some promising concretion-shaped rocks. In a very good sign, I also found a faint but distinctive fern that had already split. The finds weren’t frequent, but consistent enough to keep me searching. In addition to the cows, I was completely surprised to find my myself joined by a veritable army of black and yellow flat-backed millipedes that were marching along the ground everywhere I turned. I have never seen anything like it! Here are two of them making their way somewhere. Out in the pasture I came across this sizable cable, which I can only imagine is a remnant of the former mining activity. I ended up with about a gallon of concretions and I’m excited to see what they may hide within. I did find one additional already split fern as well. I then made a short drive to the second site I had in mind. This one also presented me with immediate encouragement, with this tiny Neuropteris pinnule showing up only a few feet from where I parked my car. Walking up and down a dirt/gravel road under construction, I found many potential concretions, including this faint Annularia and an interesting one with a productid brachiopod poking out. I collected a nice little pile of concretions from this site and made my way to the final location, where I had collected previously a few years back. Here I found at least a gallon of nice-shaped concretions, and also came across an already-split Macroneuropteris, my first mostly-complete one from here. It was a beautiful day to be outside and as a bonus I now have many concretions to start freeze-thawing- hopefully these promising shapes will pay off and I will have some new sites to start visiting regularly.

5-20-22 Ordovician Collecting in Lawrenceburg, Indiana
Nimravis posted a topic in Fossil Hunting Trips
Today a spent a little time collecting at a favorite spot in the Lawrenceburg, Indiana area, tomorrow I might hit the Lawrenceburg roadcut or AA Highway in Kentucky. Here are some pics of the area and the fossils that can be found, I only kept a select few. This location has a ton of bryozoan, as you an see from the pics below. CONTINUED ON NEXT POST-- 14 replies

A couple months ago I found a new spot in the Liberty Formation (Late Ordovician) in southeast Indiana. The Liberty is most famous for the butter shale layer producing thousands of Flexicalymene minuens trilobites, well exposed at the large roadcut near St. Leon. This new site is in the Lower Liberty (below the trilobite shale), which is exposed at St. Leon but is mostly covered by talus and thus difficult to hunt there. I was able to visit this site again last week, and I think it will become a regular spot for me whenever I can travel to the Cincinnati area. Figured I'd share some of my favorite finds from these two visits. Glyptorthis insculpta Hebertella occidentalis Petrocrania scabiosa inarticulate brachiopods attached to a Strophomena planumbona Leptaena richmondensis Plaesiomys subquadrata Plaesiomys subquadrata with an attached bryozoan The hypostome of a lichiid trilobite Plicodendrocrinus casei - I think this is the most common crinoid in the Liberty Flexicalymene retrorsa If you ever are able to collect in the Liberty, definitely do. It produces a lot of very nice and interesting specimens.

I collected this Strophomena planumbona brachiopod recently in the Liberty Formation (Late Ordovician) near St. Leon, Indiana. What caught my eye are the "bumps" near the muscle scar. I've collected and seen a lot of Strophomena brachiopods, but can't recall having ever seen these before. What exactly are they? @Tidgy's Dad

Hello, friends! If anyone can help to id this little spiny spine from the Waldron Shale of Indiana, I would be very grateful indeed. Sorry about the first pic, it's just to give a scale. The object in question is less than a mm wide at the 'base' and about 2 mm in length. It seems to be a spine with tubercles and is solid, not hollow. The picture below shows it better. Tubercles, which seem to be hollow as some are broken off. You can see quite a bit if you magnify the image : Is it a bryozoan? Where the tubercles are snapped off actually being zooecia? Or a trilobit? Any alternative suggestions also would be welcome. Thank you. Life's Good! Adam.

Pyrite Decay in Crinoids from Corey's Bluff, Crawfordsville Indiana?
Mochaccino posted a topic in Questions & Answers
Hello all, I hear that crinoids from a site known as "Corey's Bluff" of Crawfordsville, Indiana tend to be susceptible to pyrite decay. I don't know if this is a pattern but I've noticed a few crinoids from this location having black spots that I'm told are pyrite. Could I ask any members who've dealt with these crinoids or heard of this speak about their experiences? I noticed @Harry Pristis for one has some very nice crinoids from this site with such spots. I'd really appreciate any and all thoughts. Thank you.- 2 replies

I have some weak terrible pics of it, but I think this is a micro Raptor from the Triassic period, size of a cat, first time a bird evolved to dinosaur. I think it's curled up in a ball and died sunk to the bottom of the what use to b ocean for millions of years and was embedded in sand and limestone combined with the water replacing the nutrients of the fossil made it well preserved, similar to the way most matrix would house dino fossilis, except this isn't digging it out of a rock quarry somewhere, this was just a Rock at the bottom of the bottoms in a creek.

I've heard paleontologist say there will never be a dinosaur fossil found in Indiana ...
Redbearded812 posted a topic in Fossil ID
... I found a micro raptor and need help with it's verification. Pics coming soon, found in a valley in a ravine in one of the lowest elevations on earth. I can feel the skepticism just as I see it on the faces of those in the area that I have showed. I've even reached out to Indiana university in Bloomington and they have not responded to any of my emails.- 11 replies

I collected this specimen a while ago from the Liberty Formation (Upper Ordovician, Cincinnatian) of Indiana. Honestly, I have no idea what the heck it is. I posted this elsewhere and some thought it might be a strange echinoderm fragment, others thought it might not even be a fossil. Anyone seem anything similar before?
