Details:

Cambropallas Tellesto Trilobite positive and negative fossil plate of the finest quality preservation, the two halves created when the fossil stone was struck and split in two, hence the naming; a split stone, the fossil invertebrate then discovered. The limestone rock perfectly separated along with a natural seamline of Iron oxide concentrations. This often orange-red colour due to iron oxide limonite. Iron oxide was concentrated along the cephalic margins, the thoracic and pygidial pleural spines, and at the articulating lobes of the thorax. These areas of the carapace (exoskeleton) were characterized by a tight fold called the doublure.

Details

Large Cambropallas Tellesto [Formely Andalusiana] Trilobite on natural bedrock plate which has exceptional preservation to the exoskeleton which has been preserved by a process of mineralisation in absorbing the surrounding iron deposits (see the note above) of the fossil bed. Overall an exceptionally well preserved and completely natural prehistoric fossil specimen.

 

The three-dimensional exoskeleton of the arthropod displaying 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 in a dorsal keel fashion, the eye covers clearly protrude up from cephalon, each plural lobe complete and very well defined down to the pygidium.


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. 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. However, it is often the case that complete specimens are excavated in pieces and reconstructed back to the original articulated state. This is very much an accepted part of fossicking, accepted by scientific bodies 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.


 

A Cambropallas Tellesto trilobite previously referred to as 'Andalusiana'. A remarkably large trilobite of the Lower to Middle Cambrian which spanned the Fortunian to the Guzhangian ages approximately 541,000,000 to 497,000,000. A superb addition to the Moroccan trilobites of this region.
