All material was found in a lag deposit layer on SW side of highway Rt120. SYSTEMATIC PALEONTOLOGY SARCOPTERYGII Romer, 1955 TETRAPODOMORPHA Ahlberg, 1991 MEGALICHTHYIDAE Hay, 1902 Diagnosis—Osteolepiform distinguished by a cosmine cover to dermal bones in combination with a premaxillary tusk that interrupts or lies lingual to the premaxillary marginal tooth row, contact between the subopercular and the second submandibular bones, and a distinct rostral process of the supratemporal that is without cosmine cover (Borgen and Nakrem, 2016). Diagnosis—A species of Megalichthys that is distinguished from previously described species by the presence of a pineal series of bones, the presence of a triangular principal gular, and the lack of sensory canal pores on the postparietal.

We got an interesting old find from a closed locality in Germany. Comes from middle devonian and contains some parts of ?Bryozoans The former owner wrote coral on it, but no septa cound be seen. I think it is Bryozoa, but...? what do you think?

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?
