4.3" Rare Megistaspidella Trilobite - Large Specimen
This is a rare, 4.3" long Megistaspidella triangularis trilobite from the Middle Ordovician deposits near St. Petersburg, Russia. It's nicely prepared and it's caramel colored shell contrasts nicely with the light colored limestone. Both genal spines have been prepared free-standing.
Like nearly all of the trilobites from these quarries there is some restoration as the shell tends to flake when the rock is split.

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.
