Description

Freestanding Flying Dicranurus monstrosus Fossil Trilobite.

Devonian. Atchana, Morocco.
OUR GRADING FOR THIS PLATE: 5/5 ***** – Top preparation, unique flying display, rarity, authenticity.

See details in the pictures. High-resolution photos, matrix context, individual specimens and magnified views for complete assessment.

The slab is accompanied by:
a) Physical Authenticity Certificate (see 5th photo);
b) Online Authenticity Certificate - scan the QR code at 6th picture

Restoration details: Presented is one of the rarest all natural specimens of this spiny Devonian trilobite species. It suffered minor restorations - the usual little repairs on exoskeleton's and matrix's cracks and at four (4) spines tips, provoked by the extraction process.

The freestanding flying display of the spines is a laborious and very skilled work of dozens (sometimes hundreds) of laboratory hours, just accessible to very few people in all the world.

A plate like this one is a real once-in-a-life piece. Atchana quarry, after more of 30 years being exploited, is each time deeper and diggers tend to avoid it to go to other places now. Atchana's good plates will be more and more scarce from now on.

********

All our trilobites were repaired after being broken at the settlement (they were glued in the lab). The vast majority don't suffer any reconstruction (=restoration) or composition. That's something we are proud to maintain as a philosophy in our work. If so, we'll tell you for sure right here.

Legally sourced and shipped from Portugal with registered tracking.

Do not hesitate to ask any questions. We will be more than happy to provide any additional details.
