Stunning, Basseiarges (20) Trilobite Mortality Plate- Jorf, Morocco

 
 
 
 
 
This is an exceptional trilobite mass mortality plate collected at the Jorf, Morocco "red site". The entire plate measures 14.5 x 10" and there are 20 complete Basseiarges trilobites, a couple of ventral Austerops trilobites and many partials of several different species.

The rock from this locality is extremely hard with an almost glass-like texture making it difficult to prepare. The shell of the trilobites is actually translucent, so it is taking on the reddish color of the rock below.

Basseiarges is a fairly uncommon trilobite at the locality so a plate like this is a very rare find indeed. A real museum piece.

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet with over 25k described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
