1.65" Orange Nankinolithus Trilobite (Pos/Neg Split) Morocco
This is a very inflated and colorful specimen of the Trinucleid trilobite Nankinolithus from Morocco. Specimens this nice are rare, as most are compressed and missing much of the detail. It is very inflated and has a natural, orange preservation due to the oxidiation of iron pyrite which had replaced the fossil. It is 1.65" wide and 1.4" long. Both the positive and negative split are included.
This trilobite has really dramatic cephalic pits along it's "head shield". It's unknown the exact purpose of these pits, they could have had sensory purposes or aided in filter feeding.
