3.5" Hoekaspis Trilobite In Concretion - Bolivia

This is a very unusual trilobite, a Hoekaspis matacensis from Bolivia. It's preserved inside an insanely hard concretion that was broken open. The orange coloration is natural and due to the oxidization of iron pyrite.

Very few Hoekaspis retain their free cheeks like this example. This comes out of an old collection we recently purchased, so we have only one other specimen available besides this one.

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.
