Enrolled Ptyocephalus From Fillmore Formation
Here is a seldom seen Lower Ordovician from the Fillmore Formation of Utah, Ptyocephalus yersini. This box shaped trilobite is presented here in an enrolled posture. I collected this one myself years ago from a lease on the Fillmore Formation. These trilobites rarely show up on the market anymore and are hard obtain.
