246 TRILOBITE, ATHABASKIA BITHUS, Cambrian, Spence Shale, Wellsville Mtns, Utah, 4.3 cm in length, $10 OPENING BID | |
Here is a nice complete trilobite which has not been professionally prepared. I believe most of the Spence shale is off limits to collecting so that the only specimens available are out of old collections. |
