 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. Note the presence of axial spines; typically
only nodes are preserved at best. See my other offerings for
an example of another member of the genus. |
