Here is a double (almost) concrection of Portunus monspelliensis (old name: Neptunus granulatus) from the Miocene of Bosa. The left claw is crushed as you can see, don't know if because of a predation. Tips of the pinchers are restored. Sorry for the bad quality pictures, if required I will try to make better.
Anyway I'm mostly looking for other prepped/unprepped crabs, but any cool fossil could interest me.
If you have any crab for trade but you aren't interested in that just let me know, we could find an agree in other ways. Thanks
