Hello! I found these fossils(?) at Estabrook park which is part of the Devonian Milwaukee formation. They appear to be external moulds. These were found near the Lindwurm and Berthelet Members. Are these jawless fish? Big brachiopods? Non-fossils? I’m stumped on these. The formation is known for its plants, giant fungi, jawed and jawless fish, Cephalopods, and Conulariids. So sorry for the lack of scale! I need to start carrying a tape measure with my fossil hunting backpack.

I was wondering if I found an external mould of the Devonian gastropod Platyceras. The fossil curves in the rock which was hard to capture with the lighting. The rock was too big to carry back and I didn’t have a ruler with me so I apologize for lack of scale. Thanks!

Upper ordovician, Italy. Scale bar 5mm. Decalcified specimen preserved as the internal and the external mould. So the calcified occupied the space between the two moulds. 1) the only part of the external mould available. I think to see an ornamentation of narrow oblique parallel lines (red arrow). 2-3) two images of the internal mould. 4) an image of the external mould (overturned. Blue coloured) placed upon the internal mould. I think almost in the same position it was before cracking the rock. I had an idea, but the cross-shape at the bottom of the internal mould doesn't match anything in mind

I found this piece while looking through a kilo of Amber and it's a bit different to the usual - there is something distinctly fibrous inside. Usually its the internal patterns of the Amber but this isn't. Unfortunately, its super hard to photograph. I think its probably something like mold or pollen, although I can't see any distinct seed pods etc - going to clean it up a little more tomorrow. I'd appreciate any input. Thanks, John
