2.2" Super Spiny, Rare Odontopleurid Trilobite - Jorf, Morocco

Super Spiny, Rare Odontopleurid Trilobite - Jorf, Morocco #317818

Here is a fantastic undescribed Odontopleurid trilobite from Jorf, Morocco. We've only seen a few other examples of this species. It has super long spines including very long spines on each axial node. It is curled but would measure about 2.2" long if outstretched. Total restoration is less than 1% along repaired cracks.

Trilobites are collected from a 15-meter-thick section about 6kilometers northwest of Jorf, Morocco. Unlike many other localities, these rocks do not have distinct deposition layers, but rather are massive. They likely represent a gigantic "mud mound" that formed at the base of a volcanic island due to mud slides. The rock is very silicified, almost like a chert, and can be quite colorful. The actual shells on the trilobites are translucent: the trilobite tends to be the color of the rock it sits on.

Because the rock contains a large amount of silica, it is extremely hard, and preparing trilobites from the site is difficult since the rock does not separate well from the shell. Within the 15-meter section, only about two meters have been heavily collected, so occasionally this site will produce some extremely rare and one-of-a-kind specimens collected in float from the other layers.
