11" Megistaspis Trilobite With Preserved Antennae!

This is a really fascinating piece trilobite from the Fezouata Formation of Morocco. It is a large, 11" long Megistaspis (Ekeraspis) hammondi with well preserved, segmented antennae. You sometimes get soft-bodied preservation on these trilobites but I don't think I've ever seen antennae this well defined.

The trilobite has about 3% shell restoration overall. There is an area on the back-left side of the tail where shell has been glued back into place and some gap filling done. There is also an area on the upper, right corner of the head fragmented shell was glued back into place with some filled gaps.

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.
