    Double Huge Thysanopeltella (Thysanopeltis) sp. Fossil Trilobite. Devonian. Jorf, Anti-Atlas Mountains, Morocco.

    Restoration details: No restoration. 100% natural.

    Probably one of the last multiple true plates you will see from this Jorf quarry! (red quarry).

    Those specimens show affinities to the described Thysanopetltis speciosa. Also, they show some differences. Just further studies will allow knowing if we are in the presence of a new species. As the quarry is almost exhausted, this is the typical case on wich private collections will have a decisive role in academic studies.

    One of the specimens of this plate shows a healed bite on its right thoracic and pygidial sides. After the predator attack, the animal has lived, probably very naturally. The microscopical analysis shows that the tissues have made a scar and no more spines have grown from that exoskeleton area. A very interesting eco-paleontological sample.

    Multiple trilobites plates from Jorf are now very scarce. Lately, we notice some crazy composite plates from there. Simply, that doesn't exist in nature, at that place.

    This is, for sure, one of the best-preserved examples of this species we will see from Jorf, even more, because we are in presence of a multiple specimens plate, in their original positions. The size of the biggest specimen is also unusual, a huge individual. Sandblasting work is exceptional, museum-quality preparation. We can even see the eyes facets (at tiny Thysanopetltis eyes!). A once-in-a-life plate!

    The reddish colour of the specimens and the super-thin exoskeleton, with a vitreum texture (that allows no mistakes), is simply astonishing, typical from this quarry and with no parallel in other trilobites worldwide. The preparation is an almost impossible chirurgical job and took more than 100 hours at the lab. We think less than 10 people worldwide can mastered it to this final result.
