Large compressed fossil wood in Upper Carboniferous Brownsville PA
NickG posted a topic in Fossil Hunting Trips
I am currently traveling up north toward NE Ohio. On the way up while driving on US-40, I stopped off at sizable outcrops of the Monongahela Group just NW of Brownsville, Fayette County, Pennsylvania. In fallen blocks of sandstone, I came across these compressed fossilized wood. 7.1 mm between lines on the paper. Stupidly I forgot to grab my scale bar from my truck. I also stopped by Washington PA to check out the outcrops reported behind the Walmart and Sam’s Club on Trinity Point Drive. It appears these have become very badly eroded and overgrown. Maybe there’s a trick here or some better options to find fossiliferous material here but I couldn’t work it out.-

Hi Everyone, I’d like to share a few posts on the shales I’ve been hunting recently in Kansas City, Missouri. Long story short – my neighbor is digging a ‘pond’ to China. He has massive equipment from his business and so far he’s dug through about 35 feet (~10.6 M) of material. My land matches his where the dam to the pond is and I saw shale in it which really surprised me since I’ve never found shale on my property. Even in the creeks and gullies. I would also like to say that I have been really inspired by the posts from @connorp and @deutscheben about the shale they find in Illinois and wanted to show a similar collection from a specific location/member in Missouri. Here’s a rough Lithology table of my area: The pond was dug through the Winterset Limestone member through the Stark and I believe through the Galesburg shale members and into the Bethany Falls Limestone from the top of the hill we both live on! It’s absolutely magnificent. I asked him if I could take some of the shale that he went through and all he said was, ‘take it all,’ and so I did. I passed on the limestone since its way more readily available to collect in the area and I hadn’t ever hunted through shale. I’ve gone through about 250 lbs (113 kg) of shale within the last few weeks and would like to sporadically present my findings as I can make time for it. Completely unrelated to his digging I listed and sold my house and land and am moving my family to Texas. All of this has happened within a month or so. I feel that this last hurrah into shale is a way for me to say goodbye to the state I’ve lived almost my entire life in thus far. Here’s one of my wheelbarrow loads of shale. I am no scientist but will do my best to assign at least some family or species to my finds. I love the adventure of findings fossils, prepping them can be therapeutic at times and insanely frustrating at others, and assigning species is my least favorite. Probably because I am not naturally good at it. If you see a species you feel is wrongly identified please feel free to share. It’s my weak point so I’d appreciate anything that helps me get better at it. The Galesburg layer is really hard to hunt from because it’s mudstone/claystone at the top then turns into harder grey shale at the bottom. It brakes vertically into rounded blocks instead of horizontally when you try to cut or split it and destroys the fossils that it contains. At the slightest addition of moisture it crumbles and the paper thin fossils are lost. This is a chunk of it I accidentally left out one night that succumbed to the dew from one evening and following morning. It’s filled with material I am having a hard time placing but I am calling it plant material until I can more accurately identify it. Unfortunately I didn’t get hunting till a few weeks after this layer had been dug out and the vast majority if it returned to mud. Without future ado, let me begin my adventure into Missouri shale. Here’s what I believe may be part of a Calamites plant. From what I am calling the Galesburg claystone. Scale in cm/mm. Here is another unknown that I believe is some type of plant stem. The Galesburg material is so much harder to deal with that I have a lot of it in storage now to go through at a later point.

Hi Everyone, I found this specimen a while back and have been trying to identify it but have been unsuccessful. Its from a layer of shale within the Winterset Limestone, Kansas City group, Upper Pennsylvanian, Carboniferous. Scale in mm. I flaked it off a bigger piece that had bivalves in it which I'll post below. The depth of the flake is about 1/4th of an inch (6.35mm) thick. The fossil doesn’t carry through to either side of the flake. The piece at the top is the same specimen just what came apart when I cracked it. At the moment my guess is that it might be a bivalve of some sort but I can't find any that look similar. Here are some other bivalve species that were in the same section. The color difference is from me scrubbing it with a brush which removed the gray matrix. Any feedback is much appreciated as I can't find anything close.

I posted a first hunting trip with my daughter and have a few I have no idea. These were collected out of the Stull Shale member, Upper Pennsylvanian. Layer is full of Neochonetes if this helps (as in I could have filled a 5 gallon bucket without moving more than a couple feet). For reference (I cant find my photo scales) everything is 2-3cm long. Thanks for looking. Just trying to help my daughter label them before she takes them to school to show off. Crinoid Head parts? Crinoid sac parts?

I found this at the Lost Creek Dam site at Jacksboro Texas. It is the Finis Shale Member of the Graham Formatoion in the Upper Pennsylvanian Sub-period. I don't often find the apical end of any nautiloids so I was thinking it could help with the ID. There is a dark spot on the oral end that may or may not be the siphuncle, it is not clear. I thought it may be a Bactrites but it would be one without the hemispherical apex and constriction you see on some. It also has a cameral ratio higher than some Bartrites at around 3. I don't know what the black dots are.

I have found several of these at the Pennsylvanian Sub-period site in Jacksboro Texas. I've always had a good idea of what they were and never thought others might have different views until I brought up the question. If you know or have ideas post a reply and lets get a consensus of opinions before I say what I think. I didn't post this in “fossil ID” because I think I already know and I also want to discuss why they appear the way they do so give your opinion of that too. I recently found some that suggest an answer to that too. They may have already been discussed or even written about so if you know of a paper or old topic on them please post a link. I couldn't think of a good term to use for a search. Scale is mm.

I having trouble finding out what Upper Pennsylvanian Goniatite this is from the Graham Formation, Finis Shale Member. Found at the Lost Creek Spillway site near Jacksboro Texas. It is very evolute with the whorls barely overlaping. This view shows the compressed whorl section with a rounded venter. These show the flanks with sutures The venter and a rough drawing of the suture

I found this by the side of gravel road so difficult to say formation, but I'll go with upper Pennsylvanian. I think I'm seeing syringopora in the majority of this rock. There's also a small area that looks like aulopora growing on net-like bryozoan. If you can verify any of this, please do. Thanks.

I found this gastropod at the Lost Creek Dam site near Jacksboro Texas. It's the Finis Shale member of the Graham Formation, Upper Pennsylvanian Period. It has transverse costae which are more closely spaced and angle downward left to right compared to other high spired gastropods found there like Pseudozygopleura sp. My only resource is the book of index fossils and the closest thing I see there is Hemizyaga sp. but it is not on the fauna list for the site. Scale in mm.

Upper Pennsylvanian I'm unsure of the formation, other than it is likely Lansing group (Missourian Series), with a chance of being Douglas group (Virgilian Series). Found atop a weathered limestone exposure along with numerous small horn corals; various small brachiopods- small chonetids being predominant; very small crinoid columnals, and sparse plates and spines. The three larger specimens are bullet shaped, ~1cm long and ~1cm wide. The slightly smaller suspect item is more of an ovoid shape, ~1cm long and ~7mm at the widest point. Other differences include a deeper center hole in the ovoid specimen that measures ~4mm. The other three are more of a shallow depression. Fine surface detail appears different between the 'bullets', and the 'ovoid'. No apparent stem attachment point on any of the specimens. Closeup of tops: Bullet: Ovoid; Surface details: Bullet: Ovoid: I would like to mention that sponge has been suggested as a possibility for the ovoid shape. Thank you for looking!

Hi all, I found what appears to be a dermal dentical in a Muncie Creek concretion. At first I thought maybe Petrodus, but the structure seems much smoother with a flatter base and a more abrupt rise in the center. Field of view = ~1cm: Attempt at a slightly oblique view: I've also found what I believe is the same thing in the same concretion, but viewed from the bottom as it is deeply concave: Any ideas? Thanks for looking. Steve

While searching for conodonts in black platy shale, I ran across this. The scale is mm. The conodonts found are ~1mm, so this is much bigger. Upper Penn. I think Lansing group, Stanton Ls., Eudora sh. I'm guessing Phyllocarid telson bristle. Any ideas? Continued...

Upper Pennsylvanian Guessing Kansas city Group- Lane Shale- Wyandotte Limestone First a summary of the site: Nothing of note found at the limestone layer on the bottom The shale layer above contains some heavily pyritized pelycepods, Trepospira gastropods, and crinoid. Found one horn coral and alot of little cylindrical shaped pyrite(?) pellets, about +/- half inch in size. The limestone at the top is very fossiliferous, with different brach species, crinoid columnals, horn coral, and the occasional echinoid spine, all firmly imbedded and weathered. The items in question were found in the rubble beneath the upper limestone exposure. From the shale: First item for id Size approximately 10mmX8mm #1 #1a #1b #1c #1d The underside appears to be a fragment of the same thing, but there is no symmetry at all, as if it became cemented to the other side: #1e #1f Continued...
