Description: n elegant example of a member of the Order Phacopida, Subfamily Asteropyginae with many fine details present. 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 one is apparently new to science, and has yet to be described. It comes from the same location as the dramatically-spined Kayserops megaspina (see my other offerings).
