This is an excellent specimen of Acaste sp. from the Devonian of Morocco. The trilobite is quite large for the species and is well articulated. It is very 3-dimensional and has great detail. The individual facets of the eyes are evident. The cephalon displays the very fine granulations. The trilobite has been prepared so that the specimen is sitting above the matrix plate on a small pedestal. The fossil has wonderful color and contrast. This is one of the nicest specimens of Acaste sp. that we have ever seen.
