1.55" Super Spiny Cyphaspis - World-Class Preparation
This is a truly, world-class Cyphaspis trilobite specimen. This species is extremely spiny, with small spines covering every millimeter of it's head and genal spines. Due to how delicate these spines are they are almost always abraded away during preparation. Retaining these spines, requires using much lower pressures, softer air abrasives and smaller nozzles which means it takes several times as long to prepare. You won't find a nicer or better prepared specimen of Cyphaspis than this one.
