Rare Russian Trilobite Pseudoasaphinus gostilicyensis

Description: A well-inflated example of a scarce Asaphid, this is Pseudoasaphinus (once Ptychopyge) gostilicyensis, an unusual member of the Asaphidae. The golden Calcite expskeleton is complemented by the white limestone matrix, with the trilobite shown in a slightly reflexed position. Notice the fine terrace lines present on the pygidium, indicative of the exceptional degree of preservation found in this rare taxon.
