MUSEUMS CHOICE        TRILOBITES MASSIVE SLAB OF LARGE ASAPHUS TRILOBITES IN NATURAL DEATH ASSEMBLAGE

Anti-Atlas Mountain Range, South Morocco, ORDOVICIAN PERIOD:  510 million years ago
40" x 39" overall with matrix, trilobites range in lengths from 9" to 8"

This ULTRA-RARE massive slab of 26 complete and partial large Asaphus trilobites 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 pose as when buried.  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 in their natural positions.  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.
