A wonderful example of a juvenile Paradoxides acadoparadoxides briareus trilobite held in our uniquely produced custom mount, the classic range of specimens set into brass clasps. The specimen can be easily removed for handling and study. A fine and unique specimen with very good preservation. The trilobite plate has naturally formed in the earth and with care throughout the excavation and preparation process has created a stand alone exhibit. A wonderful and natural specimen in such a condition elevates this into the top echelons of trilobite collecting, from this location and time period.

The attractive colour is from the fossil bed. Heavy minerals cause the burnt umber colouration a byproduct of the heavy concentrations of iron in the region of the fossil bed and typical of this formation. This transpires as a dusty coating of fine limestone. Giving the fossil a most recognisable signature. The dark brass colour of the mounts complements the fossils.

The process of fossilisation is best achieved in an anoxic environment when sufficiently buried without oxygen bacteria cannot quickly establish on the once-living organisms and so this enables the successful and very rare event of fossilisation. The beautiful palette colours were caused by mineral absorption into the invertebrate's carapaces (exoskeleton) and surrounding matrix (fossil bedrock), this created natural earth colours which are mainly due to iron oxides being present in the sediments. The sublime and natural placement of the extinct ocean-dwelling arthropods is aesthetically pleasing with thoracic furrows and appendages creating dramatic shadowy forgotten worlds.
