of the most elegant trilobites come from the Devonian strata of
Morocco. And, in recent years availability of modern pneumatic and
air abrasive equipment have enabled fine preparation of trilobites
that come from extremely hard limestone, and were formerly and still
sometimes prepped, literally, with hammer and nail. This Hollardops
merocristata (formerly Metacanthina barrandei) from near Tafilalt,
Morocco has been laboratory-prepared with the new modern equipment.
This classic Devonian trilobite exhibits detailed articulation and
of trilobite Order Phacopida, this trilobite shares the distinction
of schizochroal eyes only with other members of the Order. The pictures
show the fine facet preservation in the eyes of this specimen.
