Perfectly Inflated Cryptolithus Trilobite - Pennsylvania

This genus of trilobite is mainly known from poorly preserved and flattened examples found in shale. Very few people have seen a perfectly inflated Cryptolithus preserved in limestone. This amazing specimen comes from the Trenton Group and was collected at a location in Bradford County, Pennsylvania. Only a few of these stunning trilobites were found, and there are very few preparators that can extract a specimen of this quality from the hard limestone. Even the free-standing occipital spine is present and completely natural.

Just check out the side profile of this trilobite in the second image to see how 3D it is.
