2" Wide, Partially Enrolled, Spiny Drotops Trilobite
This is a 2.5" wide, spiny, Drotops armatus trilobite, preserved in a partially enrolled position. This large phacopid trilobite would have been over 3" long if outstretched. This species is covered in over 50 large spines, but the spines are all broken off fairly close to their base in this example. That is the reason for the bargain price. Nice eye facet detail in the left eye, though much of the right eye has been restored.
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.
