Unusual Nodule of Trilobite Imprints

Fossils and RelatedUnusual Nodule of Positive and Negative Imprints of Large 8” Trilobite.

This unusual 10” long nodule contains the complete positive and negative parts of a 8”x 6” Trilobite, (Andalusia). The positive half is 3-D and the negative half is recessed. This is a rare condition, as the negative half is almost never found. At 550 million years old, Andalusia is one of the oldest Trilobites found in the Atlas mountains of Morocco. This specimen is reddish brown in color and sits on a light tan matrix. A real conversation piece.
