Hi, I have this mystery piece of what appears to be anomalocarid appendage of sorts. The problem is I did not receive any information with it and it came out of an old collection from Maine, Usa. I'm not to sure what else it could be from the appearance but I am also very uncertain of the exact species. The piece of a very laminated sparkly shale If I had to guess it could've came from either Burgess Shale, Utah, or Nevada but I not sure what locality it could be from so if anyone if familiar with these shales and can tell from the preservation it would be a huge help, thank you and looking fo
MDS201065 posted a topic in Fossil IDI am sorry for the length of this txt. I am looking for help verifying the ID of a fossil I've been finding for close to 20 years now. It is a very dificult to see poorly fossilized shrimp or trilobite like creature that everyone I've spoken to tells me can not exist. I am having a dificult time getting pictures that people on other sites will take seriously as the lines defining the structure of the creature are nearly undistinguishable from the stone itself. Everyone wants to call it pareidolia and say there is nothing there. Four or five individuals I've spoken to, whom have taken the t
When faced with a radiodont appendage fossil; How does one effectively determine which slab contains the "part" or "counterpart" ? For reference, here's the holotype Pseudoangustidontus appendage. The first pic, Figure A, is apparently the positive(?) "part" of the fossil. Whilst the second pic, Figure C, is apparently the negative(?) "counterpart". Like it's easy to tell the difference between an impression/cast, or the actual fossilised remains for hard-bodied specimens like shells, exoskeletons and bone. But for some soft-bodied organisms, it's especially difficult when bot
