An amazingly spinous trilobite measuring 53 mm overall, from nose to most extended thoracic spine tip. The complete 3D exoskeleton exhibits every segment of the thorax, the cephalon (head) and pygidium (tail)the axis lobe running the length of the body from the cephalon to the pygidium raised.
Pustules protrude up from the cephalon, each plural lobe complete and very well defined down to the pygidium. 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. Parts of partially surviving trilobites are stuck together to appear as one original repaired trilobite, excavated from the originating fossil beds concealing any break-lines when the reconstructed plates are built up. A competent reconstruction can be challenging to detect to the layperson. It is often the case that complete specimens are excavated in pieces and reconstructed back to the original articulated state.
This is an accepted part of fossicking, taken by the paleontological scientific community and museum services. The ratio can be as high as ninety per cent of fossils discovered are reconstructed. Only a small number come out of the fossil bed completely unaffected. Age: Lower Devonian, Late Pragian age, 411,000,000 to 408,000,000 years. Of Foum Zguid, Morocco, N.
