Brightly Colored Foulonia Trilobite - 2.4"

This is a rare Lower Ordovician trilobite from Morocco, Foulonia. The trilobites from this formation often have very colorful, natural preservation ranging from almost neon orange to deep reds. It's not unusual to see these color transitions happen on a single specimen. The color is due to oxidition of iron pyrite after the fossils were deposited. This specimen is good sized for the species at just under 2.4 long, has nice relief from the rock and is well prepared. There appears to be some restoration to the right pygidial spine.
