Ceratarges aries freestanding secondary spines Fossil 3D Trilobite. Unique display! Devonian. Zireg, Anti-Atlas Mountains, Morocco.
Restoration details: Residual - Around 40% of the very small secondary spines where reconstructed. They were missing as a result of extraction quarrying work and we decided to reconstruct them for aesthetic reason. This is a very natural situation, acceptable when in residual proportions, like in this magnificent specimen. It doesn't withdraw any value to it, as all the rest of it is natural and suffered no restoration.
This is one of the "must have" species in any spiny Devonian trilobites collection. With its alien looking and in addition to the freestanding display here presented, this is a rarely offered trilobite. The species has been recently described (Van Viersen, A. & Prescher, H., 2011) and it is one of the rarest species of Morocco. This specimen, in particular, it is very well detailed and far better than the original holotype presented at the cited paper.
The genera, sensus lato, (Ceratarges sp.) if very often badly prepared or partially faked. This one is first class prepared with the most advanced laboratory techniques (release of the matrix using air scribes and micro dust spreaders).
Our second-to-none freestanding displayed trilobites are a product from careful and laborious very skilled work of dozens (sometimes hundreds) of laboratory hours, just accessible to very few people in all the world.
