Sweet Hollardops & Austerops Trilobite Association

This is a cool, and well prepared association of two different types of trilobites from Ofaten, Morocco. There is a 2.2" long Hollardops mesocristata with excellent detail including clean eye facets. Much of the shell is a whitish coloration due to proximity to a fault in the rock where heat and/or water caused chemical changes to the shell preservation. There is also a small, enrolled Austerops which would be about 1 1/2" long.
