Here are a couple of new additions to my collection. I’ve been fascinated with crinoids lately, and am seriously considering them as an area of focus for my collecting and study. Here is a Macrocrinus mundulus from the Edwardsville Formation (Mississippian) of Indiana. The prescence of most of the arms, cirri, and anal sac are what drew me to the piece. There is an arm curled up to the right of the stem; presumably broken away from the main specimen. As well as a very small calyx in the upper right corner. I also picked up this specimen of Glossopteris browniana. It’s from the Illawarra Coal Measures (Permian) from Australia. I’m a sucker for plant fossils. This one was a decent specimen that I picked up at a good price.

I am fortunate enough to have such a huge amount of Middle Devonian Givetian material that I thought it best to put the older Middle Devonian stage, the Eifelian, in its own thread. There are some spectacular fossils here as well though! I thought a good place to start would be in the Formosa Reef, which I believe is quite early Eifelian. This tabulate coral and stromatoporoid reef continues similar complexes found from the Middle Silurian, see my: https://www.thefossilforum.com/topic/84678-adams-silurian/page/3/ thread from page three onwards for details. All these Formosa Reef specimens come from a delightful gift from my good friend @Monica who is a tad busy with life at the moment but is fine and still thinking of the forum. This outcrop can be found on Route 12 near Formosa/Amherstburg, Bruce County, Ontario, Canada. This beautiful-looking specimen came to me with only a third of it revealed but I managed to get it this far after nine days of painful pin prepping. Monica found another one and posted it for ID here: https://www.thefossilforum.com/topic/105528-weird-circular-imprints-formosa-reef-lower-devonian/#comment-1172285 The specimen was identified by another Canny Canadian @Kane to be the little stromatoporoid sponge Syringostroma cylindricum. Hardly a reef-builder, but gorgeous nonetheless. It does have a little thickness to it, but not much. Beautiful! Pretty thin, actually. I love this Monica, thank you!

This fossil was collected by a nephew at Brookfield Reservoir in New Fairfield, Indiana. I'm from Oklahoma and I'm not familiar with Indiana geology. After some cursory research, I think it may be Strophomena? Any help with ID would be appreciated.

I've had some great hikes this month with such a variety of finds. I walked several miles rock hounding and my legs were tired. I sat down to hydrate and debate if I should continue when I looked down and right in front of me was the cutest little fern. I was lucky enough to find the matching halves in the same spot! Just the energy I needed to keep going!

I found several fossil while hunting in Vigo County, Indiana, USA. I've identified many fossils I've found in this creek, but I've never found anything like this one. Any ideas out there as to what this is? It's definitely raised off the yellowish rock underneath. Any help is much appreciated. Thanks everyone!

Hi everyone. Here is a trip report from a recent visit to the Liberty formation in Indiana. I almost exclusively hunted the "butter shale". I made a 3.5 hour drive from Illinois and hunted for approximately five hours. Feel free to drop some IDs if you know them offhand. this is my first time hunting this area so im relatively unfamiliar with the flora. Here is a picture of most of my finds before cleaning: I'll start with the trilobites. I did not do as well as I had hoped in this department, but I did manage to get a few. My best trilobite was about 75% complete and only about half an inch long. I somehow managed to lose that little guy along the way, as he wasnt in my bag when I got home. As for the trilobites that made it home, here are some pieces: Next are some brachiopods. I just want to say how happy I am to have found this first one. It is in such good condition and I love the shape of it: Here are some more images of a few brachiopods I cleaned up. This does not reflect all the brachiopods I found, but shows a good representation of what is present in this formation. Here is one of many horn corals just because: And here is something I do not have an ID on. Anyone have any thoughts on this? Thanks for looking. If I return back the this site, my fingers are still crossed for rolled trilobite!

I live across the street from the Middle fork reservoir here in Richmond, Indiana and earlier today I was looking where the poor off is where the reservoir releases the water and it's a waterfall. I found this. I don't know what it is. Trying to get some help to figure it out

I went on a trip with my local geology club yesterday to the Napolean Indiana quarry and it did not disapoint! I found 30+ cystoids as well as a trilobite!

As I have learned more about fossil collecting I have been limited to surface collecting. But I have wanted to learn how to split shale and what to look for when searching for various cross sections of trilobites, crinoids, etc... in my area. Are there any books or articles I should look through and read, about shale splitting for the Indiana, Ohio and Kentucky area.

A nice Dictyonema flabelliforme dendroid graptolite from Oslo Fields in Norway. It's Tremadoc, Lower Ordovician in age and is thus maybe around 480 mya. Another angle :

IDing my Waldron Shale finds is going well, but I hit a snag when getting to Atrypa. My research shows Atrypa reticularis is a common brachiopod found in the Waldron. Also mentioned was Atrypa newsomensis, for which I could not find a picture or description of. My finds include what look like two different Atrypa species but could be the same. There are smarter members than I that hopefully can set me straight on this. The first specimens are what I feel are Atrypa reticularis. The next group are much more ornate. They remind me of Spinatrypa beulla of the Devonian.

This is an odd one my first thought at first glance was a mammal, but I'm no expert I'm just a curious extremely interested individual who loves the rocks, fossils,gems,stones etc so what u think. I'd love to learn more on how to identify them

I have a partial trilobite cephalon that I collected from the Waldron Shale spoils piles at Falls of the Ohio State Park. Since it is not directly from the quarry wall, there is some uncertainty in the stratigraphy, but it is likely Waldron or the overlying Louisville Ls. both of which are right near the border between Lower and Upper Silurian. Hopefully there is enough here to give a shot at an ID. The best I can do is say it could be Metopolichas breviceps but there appear to be some differences. Hopefully someone like @Kane or @piranha or @Ken K can see enough here to have an opinion. If not, "Trilobite Head" it will be called. Thanks for any help. Here it is enhanced a bit hopefully so you can see it better. You can see by the scale that it is under 1 cm wide. My stab at an ID initially came from Halls 1879 publication on the Waldron. Below I have my specimen between the figure out of Hall (on the right) and an example of one from the American Museum of Natural History website (left). The AMNH site says this specimen is the only known complete example which just adds to my doubt on the ID, but I have not found a more common, better match. And lastly, here is a zoom in of the cephalon to hopefully show the small bumps covering it. Thanks again for any help.

Cincinnati Museum Center Donations
Sauropod19 posted a topic in Partners in Paleontology - Member Contributions to Science
Hi all! At last Friday’s Dry Dredgers meeting, I handed over the two Ordovician fossils below to Dr. Carl Brett for the Cincinnati Museum Center! Standard business card for scale. This coral, which I have wrongly been identifying as Favosites sp., is from the campus of Hanover College in Indiana, in their Dr. Daryl Karns trail system. This was donated with permission from the Hanover College Geology Faculty. This Treptoceras sp. comes from the US-68 road cut in Maysville, KY, Kope Formation.- 3 replies

I found multiple pieces of this rock which each vary in size but the shape and structure is the same. There is banding and in the middle of each is a cellular structure looking material. Is this some sort of plant? I am in Mississippian strata Indiana USA

Petrified wood from the creek bed southern indiana
Rothrockbc posted a topic in Fossil Hunting Trips
I have collected so much from this creek over the past 3 years that I want to start documenting and sorting by type. If I could get some help with more specific and correct labeling terms I would be so grateful. I’ll just start with 2 smalls. IMG_2154.MOV IMG_2159.MOV
