This was found on one of my recent hikes in a creek bed in south-central Indiana (Monroe County). Geodes are very common finds as well as crinoid columnals and horn coral but this is the first find of this type. So I would think it is some type of geodized fossil but would like the experts' opinions. The first 3 photos (taken in natural sunlight) are "side" views and the 4th shows the "bottom". What do you guys think? Thanks in advance for your feedback.

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?

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.

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.

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.

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

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

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 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.

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'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

Hello! Amateur and fossil noob here. I was wondering if you could help me to identify these two fossils from SE Indiana. The first I found at the railroad rock cut in Madison Indiana* (corrected location below) loose on the hillside as is. Crudely it looks like a twisted up starfish. The second I found in the Waldron Shale piles that the Falls of the Ohio State Park (Clarksville Indiana) sets out for guests like me to dig through. For the second, I wasn't sure if it was a small coral or part of a crinoid. Thanks in advance - I really appreciate your help. *EDIT - my mistake. The first I found in Crawford County IN (Sulfur/English/I-64 rock cut). I had visited a bunch of fossil sites in the area within a few days and mixed them up. Results in millions of years difference!
