Kayserops megaspina TrilobiteDescription: 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 is nearly intact. A small amout of the left genal was broken during transport, and the (remaining portion) was reattached. Despite the disarticulation, this example is essentially complete, with only a small patch of exoskeleton behind the left eye restored (lighter colored patch). Totally complete and (articulated) examples typically sell for 5 times and more than the asking price here for the trilobite Riccardo Levi-Setti chose for the cover of the second edition dust jacket of his excellent photographic work on trilobites.
