Double Dicranurus montrosus perfect Fossil Trilobite 3D plate. Devonian. Atchana. Morocco. 7,2/3,6 cm
Repairs/Restoration details: The tips of the big right pygidial spine and of the big right thoracic spine from the biggest specimen were missing and were reconstructed. This is a very natural situation that often results from the quarrying work when broking the matrix. The rest of the huge specimen and all the other specimens present (at their original positions) on this magnificent plate, suffered no restoration.
The freestanding displays 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.
Most of it, a plate like this one is a real once-in-a-lifetime piece. Atchana quarry, after more of 30 years being exploited, is now each time deeper and diggers tend to avoid it to go to other easier places now. My prevision is that Atchana's perfect plates will be more and more scarce from now on.
