Hollardops aithassainorumDescription: Elegant example of a member of the Order Phacopida, Subfamily Asteropyginae with many fine details present. Notice the many eye facets present on this example. The Asteropyginae recently have undergone revision. This genus has been known in the past as Metacanthina, an entirely different trilobite (see my other offerings). This one differs from the more common Hollardops mesocristata in the shape of the cranidium and the number of lenses in the eyes. It was named for the Ait H’ssain family by Chatterton et al in 2006. Ventral trilobites have always fascinated me, so I requested that this one be prepared to show all the features of the interior. Note the scars for attachment of muscles and the hypostome which is nearly in life position. Such a specimen takes a long time to prepare, far more difficult than the usual dorsal example. The varying thickness of the exoskeleton results in the varied tones seen here. This is a most unusual example, one that would not have even been possible just a few years ago.
