Bargain, Spiny, Enrolled Drotops Armatus Trilobite - 5" long

This is a super spiny, Drotops armatus trilobite, preserved in an enrolled position. This large phacopid trilobite would be close to 5" long if outstretched and has dozens of free-standing spines and preserved eye facets. The limestone around it has been sculpted to leave it aesthetically presented on a pillar of rock.

The specimen is bargain priced because about half of the spines appear to be composites. The others were reattached during preparation but appear to be the original spines. Other than the spine repair there doesn't appear to be any significant restoration on this specimen.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
