This RARE massive slab of 13 large Asaphus trilobites (one ventrally prepared) is indeed, a show-stopping specimen. This is a NATURALLY OCCURRING mass death assemblage of these trilobites on their original matrix, prepared to expose fossils in their original positions (not added like most of these group fossils). Unlike many Moroccan multiple trilobite fossils where the trilobites are artificially assembled on matrix, this remarkable specimen is 100% natural with all trilobites found together as shown. The topic of MASS EXTINCTION is always a fascinating subject and our Earth's prehistory is filled with many tragic events with evidence of fossils like this specimen to demonstrate the sobering effects of such an apocalyptic occurrence.
After weeks of meticulous preparation in our lab, we are proud to present such an impressive museum display specimen as this. None of the trilobites possess any fabrication or restoration, only repair from the initial extraction damage. There are only fractures from the original excavation, that have been filled. The colors of the trilobites and the host rock are natural and a very unique as well as pleasing, warm blend of golden orange and brown. The slab has been reinforced on the back side with steel bars and fiberglass epoxy embedded in the original stone matrix that the trilobites are on. This amazing grouping of large Asaphus trilobites shows spectacular FULLY INFLATED THREE-DIMENSIONAL PRESERVATION and FULL CARAPACE FOSSILIZATION! Some cataclysmic event was responsible for the sudden death and burial of this ALL NATURAL assemblage of trilobites. The photos do not really demonstrate the extremely high relief and detail of this specimen. It resembles an interstate pile-up of automobiles with numerous trilobites overlapping one another in a scattered array. Many of these Asaphus trilobites display some of the best preservation and detail we have ever seen.
This is one of our most visually impressive trilobite fossils we have ever offered. Unlike many large composite Moroccan trilobite fossils, this is an extraordinarily large example that can boast of all trilobites on the slab being originally found as they are shown.
If you are looking for that one supreme large display specimen for public exhibition or a private setting, this piece is definitely one of your best candidates. It's the type of fossil that viewers will never forget. It has great value in attracting publicity but it also is a highly educational specimen, showing both, some of the exotic life-forms that lived on our planet almost a half a billion years ago and, demonstrating deadly events in past history where large numbers of creatures died at the hands of a brutal environment. Laws in Morocco have changed now and are forbidding the export of natural specimens such as this so the possibility of acquiring a piece like this in the future is discouraging. MOST HIGHLY RECOMMENDED!
