A Statement Paradoxides acadoparadoxides trilobites plate, monumentally sized statement plate containing eight individuals. Once this limestone plate formed a part of an ancient Cambrian period seabed, discovered in a region which is now the Sahara desert, the region of Sidi Abdullah ben el Hadj, in Morocco, North Africa.


Paradoxides trilobites contained in the limestone have been arranged randomly by nature. The once extinct fast-swimming invertebrates were trapped in the silts of the Cambrian. This type of seabed plate is referred to as a mass mortality plate, the explanation of the palaeontological and geological profession after analysis has concluded the death of these animals was probably due to an underwater tsunami, or similar cataclysm. The trilobites on mass, quickly covered over and asphyxiated, petrifying and fossilising the 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 green and soft rust browns, caused by mineral absorption into the invertebrates carapaces (exoskeleton) and surrounding matrix (fossil bedrock), has created these 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 furrows and depths creating a dramatic shadowy forgotten world.


Trilobites are named from the Greek, the Latin naming of 'tri' and 'lobos', the three lobes of the trilobites body. The carapace is made up of three main lobes which run longitudinally the length of the doublure (the carapace or exoskeleton), 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.


The plate was discovered in the desert mountains by our associates in the field in Morocco and prepared by fossil preparator technicians in the Moroccan Studio-Lab. Having a knowledge of collection and preparation of the specimen plate creates a unique historical provenance link to the fossil finder and digging team which enables the fossil store to guarantee the authenticity of the fossil trilobites we offer for sale.


A very brief pre-Cambrian trilobite history. The class of trilobites evolved during the Pre-Cambrian period this time 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, the trilobites reign in the oceans of the world 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, and aiding fast movement and evolution of seabed dwellers as well as some free swimming varieties.
