 Description:
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. The Asteropyginae recently have undergone revision.
This one has been known variously as “Asteropyge” and
as “Kayserops” .The rich dark brown exoskeleton is
well-contrasted to the beige matrix block. This one has been prepared
in what is termed the “flying” pose, a most labor-intensive
technique that makes for a dramatic display piece. With the advent
of a more consistent electricity supply, preparation in Morocco
has taken great leaps forward in the past few years, an effect
most certainly seen in this stunning specimen. If a less expensive
but still dramatic example is desired, please see my other offerings. |
