Metacanthina & Pseudocryphaeus Trilobite Association

This is a beautiful association of two different trilobite species Metacanthina issoumourensis & Pseudocryphaeus minimus from Lghaft, Morocco. They both have chocolate brown shell preservation which contrasts well against the light colored matrix. The preparation is wonderful and even the tiny eye facets can be seen in both trilobites. There is some very minor restoration to the edge of the left genal spine on the Metacanthina (1-2%)
