3.5" Asaphus Intermedius Trilobite With Exposed Hypostome
This is a large example of the stalked eyed trilobite Asaphus intermedius from the St. Petersburg region of Russia. This is one of the more uncommon Asaphus species from the area and at 3.5" long this specimen is quite large. Type hypostome (mouthplate) was been exposed on the underside of the head. There is a patch of shell restoration on the left hand side of the tail, and then some small gap fills between shell fractures on the right side.
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.
