 Description:
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. |
