Hello, I have a big batch of concretions from the Pennsylvanian Shelburn Formation of Sullivan County, Indiana, USA. They aren't mazon creek but a lot of the fauna seemed similar, and I wanted to ask for identification on them. Some have been ID'd generically and most of them are said to be probable partial shrimp. There are over 100 so I will split them up into a few posts. 1. Jellyfish 2. Shrimp 3. Horshoe crab pygidium 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35.

All found in Wabash County, Indiana. Any assistance is appreciated. 1. Is this a trilobite? If so, can a specific species be identified? 2. Is this a blastoid within all these crinoid pieces? 3. Is this a fossil or just geological? 4. I know these are crinoids, but is there any way to tell what that dark piece is at the end? Trilobite?

Id help! I’m not sure if this in an animal skull or just a rock
jwestbury posted a topic in Fossil ID
I have this piece from Central Indiana (Generally the Mississippian or Tertiary/Quatemary). What I find fascinating is that it appears to be a nasal cavity. I’m not sure if it’s coincidence or something of actual interest. I took quite a few pictures some with stronger flash so you can see the difference in the different light.

Question about Shale, potentially newer (pleistocene), glacial, or Devonian
jwestbury posted a topic in Fossil ID
Hello, NW Indiana here. They were doing some digging and in the sandy glacial deposit ish layers, I was finding some heavier sandstone conglomerates with Devonian era fossils(crinoids, shells etc) , and I also found some shales, they appear to be newer but I’m not 100% sure. Most are pretty flakey, haven’t found anything fossil wise inside (that could indicate a time frame better) but one of them did have a strange triangular shape inside. My question is, is it possible for other rocks to be in this type of shale? And that is just potentially what it is? Is it potentially something else? I broke it in half, (by hand, easily lol) and it’s a pretty well defined almost triangle. Not sure if it’s just a simple rock, or potential for fossil or artifact. Thanks! Jessica TLDR- can you find weathered triangular rocks with in shale, or maybe it is just shale forming around itself? Could it possibly be an artifact, fossil? Suggestions and comments are welcome. I’m not having much luck finding a lot about shale when looking online. Thanks! :) Ps-I should also mention, this was part of a larger, more jagged piece of shale, and I had broke some pieces off around the outside, pretty cleanly, to get this triangle to come out… I’ll put a picture of that in the comments.

Not petrified? But maybe fossilized.... This there a difference?
Jeff. mack posted a topic in Fossil ID
Ok found this in central Indiana.... It is sandstone about 2 feel long, it is heavy but the wood grain is only on the outside, the inside is solid. It was found just like it is after a bulldozer busted the rest of it to a million pieces, saved the biggest piece. ..... It isn't petrified wood but it sure looks like it or is it? It is kinda brittle as well. Thx for any help

Hello. I was looking at one of my old Waldron Shale hash plates and noticed a round piece seemingly connected to a Bryozoan colony and was wondering if it was the “stem” of the colony, for lack of a better word, or just a coincidentally similar piece on the bottom side of the plate. It also a smaller piece attached to the side that I assume is part of the same column but wanted to ensure it wasn’t an epibiont. Thank you!

When you took your trip to st. Leon, we’re you nervous? I read that Indiana is lame and doesn’t allow collecting on their road cuts. I plan on making the 3-3.5 hour drive there but I’m so nervous I’m going to get in trouble and I don’t know where to park lol. I’ve read recent posts of people going in the past 6 months, and no complaints or issues. Or are there any sites to find trilobites in that area? It’s not a short drive lol

Hello, New to the site and rockhounding in general. I live in Northern Indiana, close to where a glacier ended up resting, so some interesting things are in the area. Cracked open an interesting specimen and found these. I know Nothing about fossils, learning what I can rapidly, but there seem to be too many things in here to identify for my newby brain. Thanks for any assistance!

Hello! I'm very new to fossil hunting, and I would love some help IDing some that I have found! My kids and I have an eye for them, and we've spent many hours collecting anything that vaguely looks like a fossil. If anyone could help us identify them, we would greatly appreciated it!

Found Equipment someone lost at St Leon, Indiana
minnbuckeye posted a topic in General Fossil Discussion
Found these (but no trilobites) at St Leon. Contact me if they are yours.
-
Here is a trilobite I found on my first trip to St. Leon a few weeks back. Taken with an 18-55mm macro on a T6i canon. I need to work on lighting because pictures always seem to come out dull, hence why I haven't posted in awhile. I'm still working on pacifying the flaws. If I remember correctly this species is Flexicalymene meeki

Does anyone know what this is? I found this rock in the wabash river bottoms in west central indiana two years ago. It’s not quite like anything I’ve seen around here (usually I get a ton of crinoids). The equidistant branches off the central ring remind me of a vertebrae, but that just seems too good to be true.

Hi, I’m new to the forum. I’m 27 and from western central Indiana. I have been interested in fossils my whole life but only recently within the last few years tried to identify the fossils I’ve found. Yesterday I found this strange design on this rock which is probably sandstone while hiking in a small stream. I’ve never seen anything like it before. Any help identifying this would be much appreciated.

Hey all, Recently received this pair of crinoids in a trade. I have essentially zero experience with crinoids as my crinoids in my display before this consisted of just a few pieces of stem and a few inch long articulated stem. The information I have is: Crinoids Edwardsville Formation Mississippian Indiana My initial thoughts after searching online are: Macrocrinus mundulus for the tan one, and Lanecrinus depressus for the gray one Apologies for my lack of scientific terms here: I believe this to be Macrocrinus mundulus as there is this extra stalk, the tan coloration, and the thick defined plates. I believe this to be Lanecrinus depressus as it has the more "knotty" appearance, the gray coloration, and the more defined segmented arms. Any crinoid experts able to weigh in here? Does color help in IDing crinoids or is it more shape of plates, arms, and overall body plan that gives us the IDs?

Hello. I am terribly bad at stratigraphy and was wondering if I could get some assistance demarcating the cut off between the Waynesville and Liberty Formations at South Gate Hill on Indiana 1. In particular, after looking through a decent number of threads online, I have found that the "Butter shale" has been ascribed to both formations, and I'm just wondering which it belongs to. Thank you, and I apologize that I do not currently have an image of the hill to contribute to this question.

I went to St Leon Indiana, and I had a pretty good haul!!! Spent the day out there I have several fossils that are from the Ordovician time period and they’re in limestone, limestone shale. Does anyone have any good tips on washing them? Do you prefer dry? Just with a brush? What about any rusted stuff, do you use oxalic oxide? What about algae? Do you prefer water? Soap and water? Hydrogen peroxide? I’m afraid and don’t want to ruin any. Thank you! Jessica

I've heard recently that the Glen Dean Formation (Carboniferous) outcrops in Illinois are very fossil rich, especially with Invertebrates. However, I haven't heard much about vertebrate fossils coming from that formation. https://igws.indiana.edu/IGNIS/GeoNamesDetails.cfm?ID=805C6AF7-75E2-40C8-A8D2-C7535D35F7C8 Hoenig MMJ - MS Thesis - Chondrichthyan Diversity (Updated) (1).pdf Does anyone know what kind of vertebrate fauna (mainly fish) fossils are found at the Illinois outcrops of the Glen Dean Formation and if it's connected to the Burlington-Keokuk Fish Beds?

I collected this geode while exploring Mississippian exposures in Monroe County, Indiana. I was curious if anything could be said about the minerals present? I am not a mineral guy, and haven't got a clue. Thanks.

Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadcut. I've been there twice before. It is a huge outcrop, fossiliferous from top to bottom, with plenty to explore. With even a full day it is impossible to do justice to the site. As it was, I spent a half day. Most of you I'm guessing have been to or seen pictures of the roadcut. Here's a couple anyway:

Geodized fossils from the Mississippian of southern Indiana
traveltip1 posted a topic in Fossil Hunting Trips
I found these several geodized Mississippian marine fossils in southern Indiana. They may not all be hollow with quartz crystals inside, but many are. The fossils usually balloon in size in the geode-forming process. Here's 2 sides of a crinoid calyx...

A while back I made a quick stop at a small exposure of the Waldron Shale (Silurian) in southern Indiana. I only picked up a couple of items but since I have not previously collected the Waldron, I wanted to confirm (or get the correct ID) on two small items. I'm hoping one of our Waldron experts such as @Herb, @Ken K, @crinus or @squalicorax or anyone else that has some Waldron knowledge can help me out. The first item is a small, nicely preserved brachiopod. Based on what I could find, I suspect it might be a Stegorhynchus but I wanted to confirm this and if anyone can add a species, that would be awesome. Alternately, if you have a good suggestion for reference material for Waldron brachiopods, I'd love to know it and would be happy to read up some more. The black bar in each picture is 1 cm. This little guy is 1.2cm wide, 1.1 cm long and 0.75 cm high. The second item is a crinoid holdfast with a very obvious pentastellate lumen. Its also hard to see in the picture (due to some matrix and some pyrite growth) but under the microscope, you can see that the articular surface has crenulae that extend from the outer edge all the way to the lumen. I can also see in edge view that the individual columnals are very thin. Again, the scale bar divisions are 1 cm. I know that Eucalyptocrinus is a common genus in the Waldron, but from what I can find, it does not have a pentastellate lumen, but admittedly most of the pictures I see of it do not show the columnal cross sections. I'm hoping one of our members is more familiar with this genus that I am (not too hard to do) and can confirm that for me. In looking through Moore and Jeffords (1968) CLASSIFICATION AND NOMENCLATURE OF FOSSIL CRINOIDS BASED ON STUDIES OF DISSOCIATED PARTS OF THEIR COLUMNS, I see they have a species identified as Cyclochorax fasciatus that fits the description (and age and formation) of my specimen (see #7 and 8 in the snippet below from their Plate 23) but after a quick search, the only reference I see for this genus is Moore and Jeffords. I'm wondering if anyone is familiar with what a calyx of this genus looks like or if anyone has knowledge of some other existing Waldron crinoid that has this columnal pattern. Look forward to any and all responses and any help that can be offered. Thanks Mike

These were all found in Putnam County, Indiana today. Just wanted some help identifying. Thanks! 1. Very lightweight. Was able to break it in half. Almost felt like wood. I know this probably isn't a fossil, but everyone is very knowledgeable here lol 2. I know there are crinoids and sponge in here, but I'm not sure what the larger white ones are. 3. Again, I know these are crinoids, but is that large piece also a crinoid? 4. Is this just an odd-shaped rock?

This is a Crania sp. inarticulate brachiopod attached to a Eucalyptocrinites sp. calyx from the Silurian Waldron Shale from central Indiana. The calyx is 2 1/4" (5 cm) across. The brachiopod is about 3/4" across.(2cm). The blue circled item is a single element bryozoan, like the ones found in the lower Devonian Birdsong formation of central Tennessee.

Last summer I posted a trip report about finding some Pennsylvanian black shale in a river bed in East Central Illinois http://www.thefossilforum.com/index.php?/topic/106753-628-illinois-black-shale-trip-w-listracanthus/. I was able to visit the site again once more in the fall last year when the river was running much lower and collect more and larger pieces of the finely bedded and fissile shale. Since then I have been slowly splitting and going through the rocks I brought home, and finding many interesting fish parts- that is definitely the dominant fauna present, disarticulated and scattered fish remains. I have also found frequent inarticulate brachiopods, one piece of woody material and a few small poorly-preserved spiral shaped invertebrates- they could be gastropods or Spirorbis. In this thread I’ll be sharing my finds from the above-mentioned site, as well as any other ones I may find in my explorations in Illinois and Indiana.
