3" Asaphus Lepidurus Trilobite - Hypostome Exposted
This is a beautiful 3" long Asaphus lepidurus trilobite. It was collected from the Putilovo quarry in the St. Petersburg region of Russia. The caramel colored shell contrasts nicely with the light colored limestone. The hypostome (mouthplate) has been exposed on the underside of the head.
Like nearly all of the Russian trilobites there is some shell restoration but it is pretty minimal on this specimen. Maybe 3% total, on the right hand side pleural tips and a small patch on the right hand side of the head. A really nice, large specimen of the species.

About Trilobites
Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
