Lonchodomas On Top Of Asaphellus Trilobite

This is a pair of ordovician trilobites from the Zagora area of Morocco. There is a 1.45" long Lonchodomas lying on top of a smaller Asaphellus. The natural, orange/red coloration is caused by the oxidization of iron pyrite which originally preserved the trilobites.

Lonchodomas, formerly Ampyx has a distinctive, elongated rostrum and sweeping genal spines, which may have both helped to deter predators as well as providing more surface around to keep it on top of the mud.
