Acadoparadoxides Briareus

Paradoxides Acadoparadoxides Trilobite 620mm

£3,972.00 GBP

A wonderful Paradoxides acadoparadoxides trilobite measuring overall 620mm, now surmounted on to a bronze mount, part of our classic range of specimens, elevated and set into bronze clasps, the specimen can be easily taken out for study. The specimen is unique. Every fossil is unique of course, however here the quality of preservation is of an apex collection piece. The preservation is of the highest grade; the trilobite plate is cleaved from a split nodule, this is entirely a regular happenstance.

The exoskeleton carapace is in remarkable preservation all the essential features are here intact, the plate has not suffered the usual damage on the excavation. The constituent parts of the carapace are well defined here, the librigenes (cheeks) intact, long genal spines (situated from each side of the cephalon [head]) still in place and the thoracic segments (main body armoured segments) complete with spine terminations. The excellent pygidium (tail section) also present. Further, the deep furrowed central or thoracic lobe exhibits exceedingly well as light casts shadows over the whole exoskeleton. A magnificent and natural specimen in such condition elevates this trilobite to the top echelons in trilobite collecting from this location and period.

Paradoxides acadoparadoxides trilobite plate discovered at Sidi Abdallah ben el Hadji fossil formation in Morocco. This specimen fossil plate dates to the Cambrian period which is approximately five hundred and forty to five hundred million years ago. The Paradoxides acadoparadoxides trilobite beds are located in the Atlas mountains, in the Jbel Wawrmast Formation, Zagora region of the Draa Valley, near Sidi Abdullah ben el Hadj village and Alnif, North Africa. The Paradoxides acadoparadoxides trilobites covered perhaps in some underwater cataclysm which petrified and fossilised these trilobites over millions of years.

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 of colours caused by mineral absorption into the invertebrates 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.

Topical Note: This type of Moroccan trilobite plate is susceptible to forgery by unscrupulous Moroccan sellers, these copies are prolific in the fossil marketplace in Africa and the rest of the world. Because of the nature of the limestone, which is very forgiving, replicas cast from original fossil trilobites have been manufactured in the past.
