Paradoxides Acadoparadoxides Trilobite 2.2ft

£3,972.00 GBP

One of a kind Paradoxides acadoparadoxides trilobite from Sidi Abdallah ben el Hadji, Morocco which dates back to the Palaeozoic era, of the Cambrian period approximately five hundred and forty million years to five hundred million years ago. The largest specimen Paradoxides acadoparadoxides we have discovered and offered to date.


The extraordinary sized trilobite plate from the Cambrian era, in a miraculous state of preservation. Mother nature has played the greatest part in this unique conservation of the large alien-looking bug. As many connoisseur collectors aptly coin this term. When referring to the body of segmented thoracic segments and the globular cephalon (head), the pygidium (tail), spines do make for remarkable imagery particularly now that the prehistoric marine invertebrate seems to have frozen on the limestone, which was once the seabed and appears like some static insect about to jump off the plate and become animated back into like.


The trilobite surmounted on the 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.


The attractive colour is from the fossil bed, heavy minerals cause the burnt umber colouration, a byproduct of heavy concentrations of iron in the region and typical of this formation. This mineralisation develops as a dusty coating of fine limestone. Giving the fossil a most recognisable signature. The dark bronze colour of the mounts complements these colour tones.


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.


Trilobites named from the Greek, the Latin naming of 'tri' and 'Lobos', the three lobes along the body of the trilobite. The carapace is made up of three main lobes which run the length of the doublure (the carapace or exoskeleton) longitudinally, In this wonderful example above the three main lobes are well detailed and therefore easily discernible to the novice as much to the connoisseur collector. The central lobe is termed the axial lobe, each side of this are the right and left pleural lobes. These lobes run through the cephalon (head shield) and the pygidium, the tail section.


A very brief pre-Cambrian and Cambrian trilobite history. The class of trilobites evolved during the Pre-Cambrian period. This period began around five hundred and forty million years ago, the phylum arthropoda of that time were the most complex forms of animal life in the oceans. This era of the trilobites reign lasted over two hundred and seventy million years finally coming to an end around two hundred and fifty million years ago during the Permian 'Great death', a cataclysmic extinction event with saw the demise of almost 90% of life on the planet. Before this extinction-level event trilobites were diverse and ranged globally. They were complex animals, having the first compound eyes and segmented bodies enabling them to escape danger by enrolling, aiding fast movement and evolution of the seabed dwellers including free-swimming types.

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. Also, pieces of partially surviving trilobites are stuck together to appear as one original repaired trilobite, covered with reddish iron powder, excavated from the originating fossil beds concealing any break lines when the reconstructed pizza style plates are built up. Often the Moroccan plates are etched with a hatching technique around the trilobite in an attempt to hide reconstruction lines. The method is also carried out on original plates which have been excavated in pieces and reconstructed or restored, which is a different matter and not faking the original and natural product. A competent reconstruction can be challenging to detect to the layperson. Every fossil from our website thefossilstore.com comes with a firm guarantee of authenticity which can be verified.
