Trilobite: Gerastos Species

The Science

Trilobites are a type of extinct arthropod probably most closely related to modern Horseshoe crabs. With a growing number of predators and adapted to diverse habitats, various species of trilobites developed complex eyes, retractable antennae, and even protective spines. Trilobites range in size from a fraction of an inch to over two feet in length. Their exoskeletons were composed of extremely hard calcite and calcium phosphate minerals to protect the soft internal organs, and as a result they are quite well represented in the fossil record.

The Story

These nice little Proetid Trilobites have a bulging cephalon and well-defined beady little eyes. They make a great addition to any fossil collection.

Individual shapes and fossils vary but your item will resemble the pictured example.
