To continue discussion on the specimen listed here, with renewed focus on it being a Cephalopod. As of right now, I'm deciding between Solenocheilus and Ephippioceras. Going directly by the book: Index Fossils of North America (1944, 1980 printing), I can see positives for both. Solenocheilus (Lower Mississippian to Lower Permian, IN, IL, MO, KS, TX and Europe) Recommended by a local expert, but doesn't specialize in Cephalopods. Ephippioceras (Mississippian in Europe, Pennsylvanian, Ohio to Kentucky, Nebraska to Texas) The raised line along the midline of the plate photo is what is selling me on this one. My specimen is much larger than the plate, but not quite double the size. So, two new photos of the specimen. First, looking at the line: (After seeing it this way, I was looking at it 90 degrees in the wrong direction) Flipped, End over end. So, any opinions? I was thinking of removing more matrix from the matrix heavy size, but it will certainly remove the shell material and leave the steinkern.

A second large Clam or Oyster? I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer so that I could actually pick pieces up. After the heat this weekend, they were easy to pick apart once I got them home. Yesterday, I found the first piece. This is the one I found today. When it came out of the rock I was a bit shocked at how large it was. I carefully tapped around the specimen and was able to remove most of the surrounding rock carefully. This is the larger of the two pieces I found this weekend. I have less confidence in identifying it as has less features than the first piece. You can see shell material flaking off in the 3rd and 4th photos below. The fossil after I found it: Then, once I removed it from the rock:

I love and hate finding large fossils. They are really interesting and striking to look at, but I have a hard time getting an ID on them. I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer. After the heat this weekend, they were easy to pick apart. Yesterday, out popped this piece. There is another one I found today that I will be posting after this one. This piece has several wavy ridges. The shell material looks pearly, and perhaps some calcite replacement has happened. There was a piece of shell stuck on the mold portion as well. I'm seeing about 6 distinct ridges. Anyone know what it might be? Before I removed it from the rock: Several views after removing, trying to show the ridges:

Two mystery mini fossils. I’ll include scale photos, with marks at 1/2 mm. I’m on the lookout for Carboniferous Trilobites, and examples I’ve seen are very tiny in this formation, no more than 1/2 inch long.

I am nearly sure the top piece is Metacoceras. The middle is a clam, but what species? Perhaps Astartella concentrica? The bottom, what is that thing? 6477/6478 show it in detail. I find these a lot. Are they brachiopods? Not shown, but there is a horn coral on the back of the piece in a cross section.

I’ve been air scribing this piece out and I figured it was a Mooreoceras. However, the ridge going up the front is something I haven’t seen on this species. Is it just squashed a bit? It’s a pointed oval in shape. The length is nearly 3 inches.

Obviously, the tetrapod is from the Carboniferous Missippian...out by the old airport...does anyone know where that Casselman formation/Conemaugh Group is? Even though the Fedexia was found in 2004, it would be nice to resume some work and see what else is there...any ideas, any interest?
