2.5" Lonchodomas (Ampyx) Trilobite - Morocco
This is a reddish colored, 2.5" long (including spines) Lonchodomas sp. trilobits from the Lower Ordovician deposits in the Zagora area of Morocco. 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.
