Kayserops megaspina TrilobiteDescription: 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. This one has been incorrectly called “Comura cometa” in the fossil trade, but is in fact Kayserops megaspina (for “big-spined”). 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 prepared with the flaring genal spines freestanding for a dramatic presentation of this uncommon taxon. See my other offerings for an example of another member of the Kayserops genus.
