Predatory lobe-finned fish scale -
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??

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.

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 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.

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.
