3.25" Unusual Subasaphus Laticaudatus Trilobite - Russia

 
 
 
 
This is one of the more rarely seen species of Asaphus from the St. Petersburg region of Russia. It is a 3.25" long Subasaphus laticaudatus. It has a dark, caramel colored shell and it looks like it is ready to crawl off of the rock. The hypostome or mouthplate has been exposed on the underside of the trilobite.

Like nearly all the trilobites available from this area there is some shell restoration where the shell faked during collection or was weathered. It appears to be about 2-3% in total, mainly along cracks in the shell.

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 with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
