Hi group! What is your opinion? I bring you this rarity, which seems to be divided into segments, something I had never seen around here until now in my Carboniferous area. It reminds me slightly of an arthropod, maybe it could even resemble an arachnid. Or maybe they are just plant remains! Note that there are some sort of indentations in some of the fossil segments and there is an area (vaguely reminiscent of an abdomen) that is oval. It comes from the Upper Carboniferous Estephanian B (Saberien) of León, Spain. Alethopteris zeilleri

ID help. Crustacean, mollusk, or something else? Upper carboniferous.
Gramps posted a topic in Fossil ID
I have found several of these in an outcropping of shale and limestone in the Iola Formation in Northeastern Oklahoma (middle Pennsylvanian). The longest dimension is about 15 mm (≈ 5/8 inch). Some of the other specimens are slightly larger, but all have the same pattern of bumps. (I photographed this one because it shows the least wear.) I’m wondering it might be the carapace of a phyllocarid or some other crustacean. Alternatively, it might be a bivalve or other mollusk. Any help with ID would be appreciated. Focus and exposure were difficult, so there are several images. Best wishes. -
Hi Everyone, I've been working through quite a bit of shale from the Stark member and have a specimen I would like your thoughts on. My brain sees a crustacean claw due to the shape, but I think its more likely that it's a fin. What do ya'll think I have here? Dimensions are 1 cm by 1 cm. My "holding the phone camera to my microscope lens" method isn't working so well, so here's a rough outline of the shape: And the counterpart from the split Thanks,

The Namurian cyclothems in West Clare, Ireland originate in an environment of delta systems which deposited sediments in an offshore basin (Clare Basin) and are referred to as the Central Clare Group. There are five cyclothems comprising marine bands (conventionally considered to form the ‘base’ of each cyclothem) and upwards coarsening fine-grained and sandstone sediments. The five cyclothems are named (from oldest to youngest): Tullig, Kilkee, Doonlicky, Cyclothem IV, and Cyclothem V. The marine bands contain - among other fossils - index fossils in the form of ammonoids (goniati

Annularia Sphenophylloides from the Upper Carboniferous of Spain. -
Hey everyone, a few weeks ago I came across this strange object in an Upper Carboniferous, Westphalian bone bed in the Midland Valley of Scotland. This bed is full of bones, teeth, scales, coprolites etc. and is especially rich in Holocephalian tooth plates and Rhizodont bones but this object has me totally stumped, the material its made from has more of the appearance of a tooth plate than bone from this formation but I cant find anything like it. Its 14mm long. Any ideas greatly appreciated! Regards, Sam

Identifying Paleoniscoid Fishes From Linton Ohio, Upper Pennsylvanian
dshamilla posted a topic in General Fossil Discussion
If you have ever collected fish from the classic vertebrate locality near Linton, Ohio or have obtained fish specimens from there, I would like to share some of what I have learned about the type of fish called paleoniscoids (also spelled palaeoniscoids) that occur there. Paleoniscoid fish have thick, rhomboidal scales made of dentine-type bone with a surface of hard enamel-like material called ganoin and on the external surface of the ganoin there are pits and fine canals. They resemble (body-wise) what most people think of commonly as a “fish-shape” except they have “armor-like” scales. T- 12 replies

Hi. When looking at the Goniatite multiblock, from West Yorkshire, UK, I found I noticed it contains what seem to be tracks. I think they may be Trilobite tracks. They're quite hard to see but the sides of them are lines of dots. If anyone can identify them I would be very greatful. The second picture shows where the tracks are. Thanks, Daniel

My husband found this yesterday, at about 2 400 meters of height, in a place were there is no living trees. The rocks are slates and schists. It was on an hercynian volcano, rose up from the sea with the formation of the pyrenees mountains 200 million of years ago. I think it is a piece of wood. It is lighter than the stones of the same size that were around. It also exist a little chance that someone brought it there and forgot it.

I was going through some fossil containers that I haven't looked at in a long time. This came from a fossil hunt in 2009 and I noticed a tiny nodule I had picked up. I opened it the other day.. It is Pennsylvanian (upper carboniferous) and from Palo Pinto County, Texas.. At first I thought it might be a hackle fracture but once I took pics I could tell it wasn't. I am hoping someone might know.
