This is a great example of enrolled trilobites from the Devonian of Morocco. There are FIVE examples of Phacops in this set. All of the trilobites are complete and almost perfectly enrolled. The extremely inflated trilobites have been prepared with an air-abrasive machine to reveal the wonderful detail. The granulose nature of the large glabellas is easily seen, and the individual lenses of the compound eyes are clearly defined. And, best of all, this is a growth stage series, with FIVE different sizes represented! This is a great enrollment set of Phacops from Morocco.
