Two, Large Megistaspis Trilobites With Antennae & Gut Traces!

This is a very unique specimen that I've had in my personal collection for the past couple of years. It is a pair of large (7.8" & 6" long) Megistaspis trilobites with soft-bodied preservation including detailed antennae and gut traces. While I've seen a handful of these large asaphid trilobites with soft-bodied preservation none have had antenna this well defined. Just checkout the macro photos to see the segmentation on them. One specimen is been prepared with air abrasives to further exposed the antennae running underneath its head. A very unique piece.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
