Hollardops, formerly known as Metacanthina is a fairly common Middle Devonian trilobite from Morocco. They are a member of the order Phacopida and average about 2 inches in length. Well prepared examples have beautiful multi-faceted eyes. Preparation to remove the trilobite from the surrounding rock without damaging it can take many hours of work under microscope. We offer several finely prepared examples of this Hollardops trilobites for sale.
