1" Unidentified Lichid Trilobite From Jorf - Belenopyge Like

This is a rare, and as far as I know, currently undescribed Lichid trilobite from Jorf, Morocco. This new species appears to have some affinities to either Belenopyge or Acanthopyge. This one has a reverse arch to it, but would have been just over an inch long if outstretched. The hypostome (mouthplate) can be seen projecting forward in front of it's head and tail spines have been prepared free-standing.

Trilobites are collected from a 15m thick section about 6km NW 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 shell of the trilobites is translucent so that the trilobite tends to be the color of the rock below.

Because the rock contains a large amount of silica, it is extremely hard, and preparing trilobites from the site is difficult as the rock does not separate well from the shell. Within the 15m section only about 2m 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.
