A HUGE, ultra rare trilobite from the Middle Devonian of Morocco. This is a very good commercial quality Burmeisterella aff. armata trilobite. Unfortunately, only sections of this trilobite are found at any time. So, these trilobites are assembled from pieces - a quality restruction of this incredible trilobite which is found in few worldwide locations. Commercial specimens will have some damage and some repair & restoration, but they can be offered at a relatively low price. If a complete or near complete Burmeisterella sp. trilobite was found is would be valued at many $1000s. This is an opportunity to own an incredibly rare BIG trilobite. A fantastic display piece. Note - Specimen weighs 30 pounds and a supplemental international shipping charge will be applied.
