Bargain Double Gerastos Trilobite Fossil
This is a bargain specimen of the proetid trilobite Gerastos granulosus from Issoumour, Morocco. It's very 3d and quite large for the species. The preparation is a little rough hence the bargain price, but it displays quite a bit of shell detail. There are two specimens on the piece, both complete. One has some shell restoration on the tail.
