Weird Black Shale Fossil+ some conodont teeth fragments (Missouri)
Samurai posted a topic in Fossil ID
Location: Warrensburg, Missouri Period: Pennsylvanian Formation: Unknown Hello! I happened to have had an opportunity to visit land owned by one of my friends and decided to split some of the black shales. I happened to come across something that seems familiar but I just can't seem to place a name on it as of yet. So far I have found 2 specimens, and I'm not sure if one is just infilling of the original mold or something other. Unfortunately they were in already weathered sections of shale and I could not retrieve the other halves of the shales. In case it helps with i -
I found these while splitting some black shale collected at a private club in Grundy County. The first 3 pics are of one specimen and the last 2 are of another specimen but not as well preserved. Thanks.

Looking for some ID help on this plant fossil. Found in black shale in the Allegheny Formation (Pennsylvanian age) in western PA (Lawrence Co.) The fossil is approximately 3" long.

Black shale collected at a private club. I’m not sure just a linear artifact of the shale or a linear structure of something.

Unknown Microfossil from Pennsylvanian aged Excello Shale in thin section
Samurai posted a topic in Fossil ID
Hello! I was making some thin sections of some material from the Excello shale and found a very large and bizarre structure. Sorry in advance it was too big for my microscope camera to really capture it all, but here is the specimen in question its most likely coated in apatite/phosphate? along with small radiolarian/sponge spicules surrounding it I sent a photo to my professor and he said it could be something new but he would have to see it in person (he is an expert in Radiolarian microfossils) I wanted to post it here and see i-

Yesterday I went on a combined field trip with ESCONI and LOESS to the Starved Rock Clay Products pit in Utica, Illinois. ( @connorp was there too!) This open pit exposes the Pennsylvanian Mecca Quarry black shale, Francis Creek shale, Colchester Coal, and an underclay below the coal- an assembly of strata that have produced world-renowned fossils elsewhere, including Mazon Creek fossils further east and complete sharks from the Mecca Quarry Shale in Indiana. At this location, unfortunately, the concretions are almost all blanks but the black shale does produce isolated fauna including bivalve

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 presen

Howdy all, I did a bit of fossil hunting in Fayetteville AK over Thanksgiving, hitting the Mississippian age black shale the area is famous for, looking for goniatites and any other ammonoids or nautaloids I could find. These concretions were dug out of the lower unit shale and many of them were large, extending over 4ft in length, flat, with an oblong appearance. This was on the surface of a concretion and unfortunately was exposed to weathering and moisture. Not sure what that is. This little guy, it’s just provided for grins and not requesting an ID. It

This was collected at a private recreation club west of Pit 11 from old spoil hills. I have found Listracanthus spines from this type of black shale. I’m not sure if this is a large spine or something else. Thanks

This is black shale from southern Grundy County, Illinois from a private rec club found in the spoils hills throughout the club. I have found a few listracanthus spines and numerous bivalves from this area. I am unsure as to what these structures are but thinking a type of mollusk or ammonite. Pics 1-3 is one fossil and pics 4 and 5 is another fossil. Thanks

Last weekend I decided to take a short drive to Vermilion County, IL and get outside for a little bit. I haven’t been able to do any fossil hunting since COVID-19 reached our shores, so I had a few iffy sites less than 40 minutes from home in mind as I was driving. The first two proved fruitless, but I decided on a whim to take a new road over a local river in hopes of finding some exposures there. The river was running high with verdant growth all around and dragon and damselflies filling the air. As I looked down from the bridge I saw sandy shore, concrete bridge abut

So, while looking for shale that may have plant imprints (nadda ) or conodonts (also nadda ) and finding absolutely nothing splitting open countless layers (I wanted to make the shale layers in Kansas City look uniform so I've separated all of them for future fossil hunters ) I came upon this single fossil. To me it reminds me of modern-day smooth shelled limpets. This black shale layer was between winterset limestone and Sniabar limestone layers in Kansas City (from R. Gentile). It is about 3/8" long by 2/8" wide and a little over 1/8" thick-two different "lightings". Thoughts, as usual, m

This is a very odd fossil that I collected from a Pennsylvanian aged black shale site in North Central Illinois. i have been collecting this site for many years and have never found anything like it. The specimen measures approximately 3”. The site primarily consists of a Thylacocephalan type arthropod along with a variety of fish and a few nautiloids. it is very similar to the Mecca Quarry Shale of Indiana. My best guess is that it is some type of nautiloid or possibly a spiral coprolite. Any suggestions would be appreciated.

Here are a few things I would love to know what they are: #1 Black shale that we used years ago to make a decorative siding for the barn, what are those shallow pits? This rock is about 7 inches long. #2 This came from a different area in the Eastern Panhandle that was near a large creek. #3 Same thing as #2? Thank you for your help!

So I finally have an answer to the identity of this fossil I found in a rock quarry in Crescent, Iowa back in 2015... it has been identified as the back half of a eurypterid with the telson attached and nacre. This is a very unusual find for the location and the age of the shale.

A Very Good Problem to have in the Carboniferous
fossilized6s posted a topic in Fossil Hunting Trips
In the last two weeks i have found two new very promising fossil sites. They are on private land that i have permission to be on. And please don't ask where. There are so many things that i have to leave many behind. I hope i am lucky enough to find something truly amazing from these sites and share them with science and ultimately all of us. I believe this to be the first Orthacanthus sp. specimen ever found in this area of Illinois. It would be pretty neat to add this awesome predator to this fauna. As found: After prep:- 27 replies

I found what looks like a tree cast fossil in black shale layer but it does not look like what I have seen on display. It to me made of a very fine grain sediment and peel off in layers. I could see a complete log imbedded in the shale on one of the upper layers appears to be less than a foot in diameter.

I went down to a new spot i found to see if i could find more Carboniferous shark teeth. Sadly, no teeth. But i found this oddity. I've personally have never seen anything like it, and it kind of reminds me of shark skin, but i'm leaning more towards a strange trace fossil. In the upper right corner and top center you can see symmetry somewhat in the shape i can only describe as a sunflower shape. Other than that the spots seem random. Any opinoins are welcome. I've been searching and searching without any luck. Thanks, guys and gals This

I dig around in Devonian black shale quite a bit looking for nice pyrite crystals, etc. Is there a legitimate concern for me regarding radioactivity within that black shale? I ask because I stumbled across an article that mentions the radioactivity content of minerals in black shale. TIA!
