Hello, I found what looks like a worm on a block of limestone too large for me to split. So I took a picture of it. It is about 4 cm. The limestone is Carboniferous, Pennsylvanian and from the Glenshaw Formation. Thanks for the help!

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!

As I continue to explore (see my prior thread Earlier today I visited the Upper Freeport Formation south of East Liverpool. These are sandstones associated with the Upper Freeport coal, so we are at the end of the formation. I have been up here repeatedly over the past year but never explored rocks this old in the area. It was snowing for about two hours this morning but I still spotted some cool fossils. Unfortunately while I saw the Upper Freeport coal, I didn’t have the opportunity to collect in it. Here are two separate medium sized impressions of lycopsid trunks. I then moved further into younger sediments, revisiting where Pteroplax was collected (Romer, 1963). This is a well known site in the literature, reported in most of the Ohio Pennsylvanian age invert reports of the latter half of the 20th century. I’ve been here before, though we mistakenly descended to the base of the cut along the rail line which was frustrating. The circumstances of how Pteroplax was collected are interesting. Look the paper up. That unit it was produced from is no longer evident and completely overgrown and slumped but it’s fine because I was here for the Ames limestone. Everything I collected here was typical of what I have seen of the Ames limestone in eastern Ohio so I have omitted pictures. Afterward I moved on to another section that exposes a larger portion of the Glenshaw Formation (the Ames is the terminal Glenshaw transgression, the Upper Freeport coal is below the Glenshaw’s lowest unit). Here are some Pine Creek (Upper Brush Creek) brachiopods. One is a productid and the other is a part and counter part of a spiriferid (?Neospirifer). In the Cambridge limestone, we found this badly preserved snail. Perhaps with some preparation, it can be identified further. It is fairly beat up. At this locality, the Cambridge is very coarse grained and hard. The snail is not exhibiting the typical preservation qualities of other invertebrate fossils found here. In a younger unit, I found this partial Deltodus tooth as well as a possible actinopterygian scale (I have my doubts but friends are certain). Both are hanging out with broken bellerophontid snail pieces. Tomorrow I will be in the Mercer (Pottsville Group) which is older than anything you’ve seen in these two threads. If I find anything worth sharing, I’ll share! In the future I will be updating this thread for the entire month (and maybe the year) instead of starting new threads.

Hello, This specimen comes from the Pennsylvanian Period of Allegheny County, PA. It is from the Glenshaw Formation and is probably Brush Creek Limestone. The texture appears to be bone. Thanks for the help.

I just don't know what this thing is. It's from the Glenshaw Formation of Allegheny County, Pennsylvania. Some is below the matrix, but what is showing is about 1 cm top to bottom and 1.5 cm across. I believe it is Brush Creek Limestone and it looks like part of a fish spine to me. As always all help is appreciated. Thanks.

Hello! I think I've just about tapped out most of my local hunting spots. Yet a week ago I found a couple fossils that look like teeth. Please let me know what you think. They are 1.5 cm wide by 1 cm long, Pennsylvanian (Carboniferous), Glenshaw Formation and from Allegheny County, Pennsylvania.

A few weeks back I made a short stop at the roadcut in Aliquippa, PA, and I found a good bit of plant material in the half hour I spent there. This plant fossil I found when I split a slab of shale. Seed cone, perhaps? Glenshaw Formation, Mahoning Shale member

I have no idea what this thing is. I found it in Allegheny County today in the Pennsylvanian Glenshaw Formation in what I think is Brush Creek Limestone. Unfortunately it is only part of the fossil, but I thought the pattern might tip someone off as to what it is. Scale is in metric. Thanks for the help.

I found this piece on Friday. I thought it was wood, hammered it out, collected it in a tiny bin, and took it home. Saturday evening I put it under the scope and was surprised to see the texture. I've collected wood before and the grains are typically tighter. It also looks very similar to recovered Petalodus or fish root material I've seen. This deposit has a lot of different shark teeth, at least four unique genera are present. The limestone has the characteristics of a dynamic wash, where a lot of material was gathered and deposited quickly. Not that it helps a lot. I've never found shark bone or cartilage, so I don't know exactly what to look for. Scale bar = 5 mm.

I found this in a local stream several months back. The bedrock is Pennsylvanian and in the Glenshaw Formation. It feels strangely heavy for just a rock. Sorry, the scale is in inches. It's about 10.8 cm long. All help is greatly appreciated, thanks!

I have no idea what this is. It's unlike anything I have found. I split it out of Brush Creek Limestone today. Pennsylvanian Period, Glenshaw Formation. It's about 25 cm in circumference at the base. I would guess cephalopod, but it's much bigger than one's I've previously found. Help is appreciated, thanks!

I’ve been trying to ID this huge cephalopod I found from the Glenshaw Formation in Brooke County, West Virginia. So far, I’ve considered the following: Millkoninckioceras Kummel, 1963 Mahoningoceras Murphy, 1974 I was all in on the latter name until I noticed the sutures were fairly straight compared to the deep convex flank sutures. Whitney (1882) called the sutures deeply concave on the holotype of Mahoningoceras (original description in photos below). The umbilicus is open. The specimen appears to be flattened. I believe the ventrolateral shoulder is about the middle of the bottom whorl in the second photo with a scale. The largest coiled nautaloid I've found in this formation could fit within the center whorl of this specimen. It seems that the body chamber would add another 1/4 whorl length. With metric scale: Coated with paraloid:

Found this critter in what I believe to be the Brush Creek Limestone. It is Carboniferous (Pennsylvanian), Glenshaw Formation, and looks like a nautilus to me, so I'd guess Solenochilus. Thanks for the help.

Howdy! I found a beautiful pseudorthoceras last week and last night I noticed a tiny white organism on the rock. It looks like several "Vs" strung together. Fossil is 0.5 cm, is from the Glenshaw Formation and likely Brush Creek Limestone. I have no idea what this thing is. Thanks for the help.

I found some pyritized plants a few days ago and noticed that one looks like a stem with seed pods. The fossil measures 2 cm and is from the Glenshaw Formation of Beaver County Pennsylvania. I'm nearly certain that what looks like a stem is a stem, but what are the three round things seemingly attached? Help is appreciated, thanks.
