3.5" Spiny Phacopid (Drotops Armatus) Trilobite - Perfectly Prone

Spiny Phacopid (Drotops Armatus) Trilobite - Perfectly Prone #196640

At 3.5" long this is probably the smallest, complete example of Drotops armatus I've seen. Most specimens are closer to 5"+ in length. It is laid out perfectly prone and aesthetically presented on a rectangle piece of limestone. Unfortunately it looks like most of the spines were broken off during the initial preparation.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
