Looking for some experts on these attached images. These are just ones I can’t figure out. Scale in metric. I had a successful hunt at the end of 2023. Soon I’ll be adding a photo album of this and some of my other finds from various locations. Overall, I found Ageleodus pectinatus teeth, Hyneria lindae teeth and scales, Megalichthys mullisoni scales, Langlieria radiatus scales, Holoptychius sp. scale, acanthodian fish spine, Phyllolepis rossimontina armor, Turrisaspis elektor armor, and plant leaves and stems. EDIT: Location - Clinton County, PA.

I brought out a bag of Devonian brachiopods from the Cerro Gordo to clean up this week when I noticed this unknown in amongst the shells. At first I thought geologic but if you look close, it appears to have six sided symmetry. So is this some sort of echinoderm??

I've been chipping away at this cobble when I have spare time, and slowly exposing this fossil. I found the stone itself in western Illinois, relatively near the rivers. The matrix is shockingly tough, I can only rarely make a difference with any sort of precision, unpowered hand tool. Each grain of sand is firmly in place and does not want to leave. The exposed matrix was originally reddish to brownish, though newly exposed faces of chips broken off lack the red-brown color (the reddish color is entirely lost in the photos). Presumably the stone is Mississippian or Devonian. Other fossils in this rock are all flakey white brachiopod material ranging from 0.5 cm to 4 cm across at the widest points. I have tested some matrix scraps against vinegar, which dissolved the stone around the sand grains, but left the sand grains untouched. I've decided to hold off on any more matrix removal until I know what I should expect to find in the matrix. I found a second one of these, but it chipped off and lost it in my prep area outside. When it comes to the horses & zebras adage I always put more consideration into the zebras than I should, which is why I'm hoping this is some part of a vertebrate but more likely an oddly colored crinoid bit. We just don't have much vertebrate material where I'm at. The photos with circular borders are taken through a stereoscope at 15x magnification. The others have some level of digital zoom applied, but have a scale nearby (mm, cm). I apologize for any focus issues, this new phone has a finicky camera.

Trilobite Fossil real or fake?
Toast123 posted a topic in Is It Real? How to Recognize Fossil Fabrications
It was collected from Bou Dib Formation near Mrakib. Im wondering if they are authentic or fake. Why is the stone they’re on a different color than the rest of the rock?

Devonian Ammonoids, Cephalopods, and More from Foreknobs Formation of New Castle, Virginia
fossil_lover_2277 posted a topic in Fossil Hunting Trips
Hiked up to some Devonian Foreknobs Formation exposures yesterday on a mountain in the Jefferson National Forest in Craig County, Virginia. Found some awesome and beautiful ammonoids, cephalopods, and more!!! Now I’ve just gotta find some trilobites and crinoids...lol Some of the better ammonoids I found in some mudstone: Some of the different types of cephalopods along with some brachiopods: And 2 unknowns, not a clue in the world what these are:

Recently I have taken interest in fossil hunting after discovering a plethora of fossils from some farmland in Southern Indiana. It is my understanding the fossils are from the Devonian period. My grandsons (5 and 6 years old) and I have collected several specimens I’ve the last couple of months. I have been searching the Internet for weeks trying to correctly identify our finds and just when I think I have something identified —I find other possibilities. I would like to make displays for the grandkids and label our other collections appropriately. I am in hopes this community would help identify the specimens, and provide advice on how best to label the fossils. I appreciate any assistance that can be provided. Thanks. —Bill Shingleton PS: All the fossils depicted are from Jeffersonville, IN.

Bivalvia Deep Springs Road Quarry, NY Windom Formation Middle Devonian -
Curious about this piece of fish bone. From a Middle Devonian (Givetian) site. It's fragmentary and weathered, but the weathering exposed some interesting structures on the underside, consisting of parallel rows of indentations. Not sure what to make of it. Any thoughts?

Found this specimen in Pike County, PA. Here are some photos from different angles! This fossil has taken me in all different directions with regards to research. I have been unable to discern what this find may be. If anyone has an idea, I’d love to hear it! (My guess) Lepidodendron or Archaeopteris sapling branch??

Found this specimen when hunting just outside Danville, PA in a roadcut near the Susquehanna river. This is from the same visit as my previous post. The location is Trimmers Rock formation. My best guess is Leiorhynchus but I'm pretty stumped on this one.

Found these specimens when hunting just outside Danville, PA in a roadcut near the Susquehanna river. The location is Trimmers Rock formation. I'm fairly certain that these are brachiopods but I haven't been able to ID them with any certainty. Mainly at that site we find beautiful Mucrospirifer specimens. However, these specimens appear larger and don't, to me, seem to be Mucrospifier. Most of the research I've done has yielded IDs that seem to be typically smaller than what I found. The first image shows the two parts together, the second shows them side by side with the top piece flipped over, the third shows the bottom piece and the fourth shows the top piece. My best guess is Leiorhynchus.

Been finding a lot of these in the mahantango formation, but have been unsure of what they may be. Alongside these (what my untrained eye sees as) Spores, I have found many “V” shaped branches, with the little knowledge I have, my first thought is Cooksonia.. Hoping someone with more knowledge can provide a definitive answer! There are three examples within this one rock and I have many stems in other rock!

Brachiopoda Smoke Hole Canyon, WV Corriganville and Oriskany Formations Early Devonian -
I recently purchased this fossil found in the Ketleri formation of Latvia. It had little information given with it and no label when it arrived, so all I know about it is that it comes from the Upper Fammenian of the Devonian and that the two fossils in the piece are not associated. The placoderm armor section is in all likeliness Bothriolepis, since about 70% of fossils from the formation are from that particular animal as far as I could find. The vertebrate bone is what I'm wondering about though, even though it is a fragment I am interested if it could be identified. It is about 2cm long, both ends are broken off but the break shows a pretty large internal cavity going straight through the bone. Would anyone know how to identify it, even if just to a broad group of animals?

Trilobite in Matrix

I have some images of a trilobite fossil I am interested to collect. Can I have some opinions if it is worth collecting and if it’s legit please.
