8.6" Cruziana (Fossil Trilobite Trackway) - Indiana
This is a fossil trackway (cruziana) of an arthropod, in this case, a trilobite, collected from the Mississippian aged Tar Springs Formation in Perry County, India. The two rows of evenly spaced lines show where the trilobite's legs would push up the sea floor, leaving tracks similar to the way a tire leaves tracks in the mud. The cruziana measures 8.6" long.
Comes with an acrylic display stand.

About Trilobites
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.
