Kayserops tamnrhertaDescription: An elegant example of a member of the Order Phacopida, Subfamily Asteropyginae with many fine details present. Notice the fine eye facets present on this specimen. The Asteropyginae recently have undergone revision. The trilobite called “Kayserops’ in the fossil trade is actually Metacanthina issoumourensis, a far more commonly-available member of the Asteropyginae. This specimen has been named Kayserops tamnrherta by Chatterton et al, with the species name derived from the Berber name for a small black and white desert bird.
