3.4" Asaphus Punctatus Trilobite With Fossil Cystoid - Russia

Asaphus Punctatus Trilobite With Fossil Cystoid - Russia #191013

This is a nice, 3.4" long Asaphus punctatus associated with a fossil cystoid (Echinosphaerites?). The Asasphus has beautiful shell preservation and large stalk-eyes. There is about 2-3% shell restoration, mainly on the tail where the shell fractured during collection.

It comes with an acrylic display stand.

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.
