Hi folks,, I am always looking for concretions with fossil crabs, lobsters and shrimp to prep out. I have lots and lots of stuff to trade! and some rather good stuff too!! all fossils though. I can also send photos too. thanks RB
I'll get back to you tomorrow mate...I am seeing a friend tomorrow who has multiple specimens of entire freshwater crayfish in perfect concretions with excellent detail and both claws. I'll get some pics for you.
