.25" Rare, Enrolled Upplandiops Calvus Trilobite - Russia

Rare, Enrolled Upplandiops Calvus Trilobite - Russia #191316

This is .25" long, enrolled Upplandia calvus trilobite from the St. Petersburg region of Russia. It comes from the Veltsi Formation which is Middle Ordovician in age. If this specimen was fully outstretched it would measure around .8" long. The shell is in excellent condition and great care was taken to prep this specimen. This species is rare and very little is known about it.

A small acrylic display case is included.

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.
