Bargain, 2" Fossil Prochasmops Praecurrens Trilobite - Russia
This is a 2" long Prochasmops (Chasmops) praecurrens trilobite from the St. Petersburg Region of Russia. This is a fairly rare trilobite. There is some disarticulation through the segments and portions of the left side of the shell are incomplete, hence the reduced price.
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.
