Hi. This is on the Caney River, middle of Washington County in northeastern Oklahoma. It's in very hard matrix, can't do more than make a scratch on matrix surface. Pennsylvanian. Abou4" long, no more than 5" long. In the third picture what looks like a crack across the middle is just a shadow. Thank you.

Hello again Fossil friends! I have another fossil I need help with. Found with other shell and coral fossils in a river shore in north eastern Kansas, most likely Pennsylvanian. It looks to be maybe a sponge with exterior and interior... structure? Couldn't figure this one out. Maybe someone with more knowledge can ID it for sure.

Hello Fossil friends! I have a couple fossils(?) I'm going to see if I can get help identifying. I found all of them in the same local area of a river shore in northeastern Kansas, so I'm assuming Pennsylvanian time frame. I have some fossils that are obvious shells and coral, but these I'm not sure and would like your input! If you need more photos or angles, let me know. #1 I think is a fish vertebrae that's slightly flattened. It's about 1 cm x .3 cm.

There are fossils in the background gray sedimentary, but so much better preserved in brown! Why? Almost like this pile of creatures is on display, a 7 inch blob just laying on top of gray stone. I'm more interested in how these were preserved than what they are.

Hi. I know these are poor pictures so I understand if nothing comes from them. This 3' by 3' boulder looks like a big dirt clog up close but is solid. It is in central Washington County, northeastern Oklahoma, Pennsylvanian I think, on the Caney River. 99% of the ground you see it sitting on going down the river and around the bend is coral, but I see no coral in this boulder or the only other boulder (out of view). In this post, the lower middle spot in all three pics is what I am curious about. It's about a foot wide.

Hey everyone, I recently got a bunch of stuff from Mazon Creek, which I have zero experience with. I would really appreciate some help in identifying this stuff, so here's a few of the things. Everything is from Mazon Creek Pennsylvanian in siderite concretions, the scale bar is in mm. The picture labels are what came to mind looking at them. Thanks Everyone!

From the album: Missouri Plant Fossils
When this came out of the earth I was shocked by how many were bundled together as I mostly find only fragmentary pieces of one specimen. The small limestone chunk on the left is a piece that came undone at the site I found this fossil at. More images of these fossils: https://imgur.com/a/KnjIeqG Correct id by Fossildude19 -
Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I was cracking Phosphatic concretions and this baby popped out! I was excited and thought I should share and ask what it is! I believe it is a cartilaginous fish spine, but I have little knowledge in such topics. Ps Information on good glue to glue together the cracked piece is welcomed!

It's been a long time since I've written a trip report. Not that I wasn't hiking, I was hiking like mad and finding stuff. Just didn't get around to documenting in the latter part of 2020. Too much craziness. A couple of days ago, I went in search of an extremely elusive shale formation, that contains some of the loveliest ferns I have seen. My records show I specifically planned 13 hikes last year trying to find another exposure. That was over 100 miles of fruitless searching. Zero. Zilch. Well, two days ago I found another small exposure. Scenic photos of the journey follow starting with walking uphill on an Ordovician rock bed The Ordovician transitioned into this Silurian bed with Devonian formations rising above it on the left Although fairly stumble-free walking this was relatively steep. That day I ascended 2,800 ft with my big pack full of tools, food and drinks. A nice shattered chert nodule in the Devonian. Just to show not everything has fierce thorns here, some 'Cushion Buckwheat'

While organizing today, I came across this Composita I collected a while ago in the Pennsylvanian of Illinois. I noticed it had something encrusting it, which was surprising since brachs from this site never seem to have any encrusting organisms. Whatever it is, it is not preserved super well, but it almost looks like a tiny productid brachiopod? Never seen anything like it. Any thoughts? @Tidgy's Dad

Mystery critter -Kiewitz Shale- SOLVED brachial valves still working on genus
LabRatKing posted a topic in Fossil ID
Finding a complete specimen is my white whale. Usually only find small fragments, these three are my most complete. Am able to use a few bits to get a “reconstruction” cannot figure out what these are. thanks in advance!

Happy Friday from Albuquerque, New Mexico! We have been hunting for fossils in the Sandia/Manzano mountains just east of Albuquerque, New Mexico. Our beautiful back yard. . . Pennsylvanian fossils can be found in the limestone that is exposed at the top of the Sandia Crest and east of the mountain. We mostly find brachiopods, crinoids and bryozoan. I found this on the hills of Cedro Peak, and it's not like anything we have found up there. Thought it might be a crinoid stem, but looks different. Any help identifying would be much appreciated.

I wonder if anyone may be able to help determine whether this is a bone, and whether it might be from a fish or a tetrapod? It was found in the Middle Pennsylvanian Wewoka Formation of northeastern Oklahoma. It may take me 3-4 postings to upload all 7 images. Best wishes.

13 Gymnophyllum wardi Peculiar 08 Enlarged attachment area
Gramps posted a gallery image in Member Collections
From the album: Pennsylvanian Fossils of Northeast Oklahoma
This young, possibly ephebic, corallite had a very deep attachment area on bottom. This rapid upward growth may have occurred in response to—you guessed it: Sinking in the mud.- 1 comment

From the album: Pennsylvanian Fossils of Northeast Oklahoma
The next few images will show some of the many growth forms of Gymnophyllum wardi, a solitary rugose button coral. G. wardi is the only known species of the genus. It is locally common in the Middle Pennsylvanian (Westphalian) Wewoka Formation in Okmulgee County Oklahoma. Fossils of the species also occur in the lower part of the Labette Shale in Rogers County Oklahoma. The tiny corallite in this image displays many characteristics of the early, neanic, stage of growth, including crooked septa and a deep central pit.-

From the album: Pennsylvanian Fossils of Northeast Oklahoma
This tiny Gymnophyllum wardi corallite shows neanic characteristics, including long septa that extend from the center of the calyx to the periphery. Also, at the center of the bottom side, you can see the small area where the corallite attached to the mud in shallow, calm seas where these corals are believed to have lived. -
From the album: Pennsylvanian Fossils of Northeast Oklahoma
This Gymnophyllum wardi corallite exhibits characteristics associated with the ephebic (maturing, or nearly mature) stage of growth. For instance, note the beginnings of a central dome on top.-

The Gymnophyllum wardi corallite in this photo shows various ephebic characteristics, such as the insertion of minor septa between the central dome and the periphery. -
From the album: Pennsylvanian Fossils of Northeast Oklahoma
This likely ephebic corallite of Gymnophyllum wardi displays the notched septal ends that are often seen in this species. -
06 Gymnophyllum wardi Mature Specimen 01 Domed top, Fused Septa.jpg
Gramps posted a gallery image in Member Collections
From the album: Pennsylvanian Fossils of Northeast Oklahoma
This specimen of Gymnophyllum wardi appears to be mature, having a broad, smooth central dome on top and fused septa that are visible mainly near the periphery. This species grew by spreading horizontally, a process that often left conspicuous growth lines on the bottom surface of the corallite. -
07 Gymnophyllum wardi Mature Specimen 02 Domed top, Fused septa, Predation Damage.jpg
Gramps posted a gallery image in Member Collections
From the album: Pennsylvanian Fossils of Northeast Oklahoma
This mature Gymnophyllum wardi corallite looks like a pie crust due to the prominent central dome, fused septal ends, and the three apparent wounds on top. Fusing of the septa served to increase the surface area of the base. This may have kept corallites from sinking in soft mud. -
08 Gymnophyllum wardi Mature Specimen 03 Flat top, Unfused Septa
Gramps posted a gallery image in Member Collections
From the album: Pennsylvanian Fossils of Northeast Oklahoma
Some mature specimens of Gymnophyllum wardi had low, flat tops. Again, note the fusing of some (but not all) of the septa near the periphery. Also see the prominent growth lines on the bottom surface.
