Rare True Acanthopyge
Lichida, Family Lichidae, Subfamily Trochurinae
Time: Middle Devonian
is 77 mm long by 673 mm wide (counting spines) on a 110 mm by 105 mm matrix
Djebel Mrakib, Morocco
Unlike the trilobites recently coming from Jorf that are known as
Acanthopyge there is another trilobite with substantially different
morphology that is assigned to that genus. This remarkable specimen
is an example of that genus known as Acanthopyge haueri. More than
a decade ago a few examples of this trilobite were found near Mader,
Morocco, and the quarry was quickly played out. A search for another
site was carried out, and a quarry was established at Mrakib for a
similar trilobite. While quite similar to the original, this one has
a smaller pygidium and longer pygidial spines. For the sake of this
listing it will be termed Acanthopyge aff haueri, showing its affinities.
Perhaps at some point this one will be afforded a scientific description.
This one has been prepared with both the genal and pygidial spines
freestanding. As is often the case for spiny trilobites such spines
are removed for preparation and then reattached. I have included two
in-preparation photos showing early stages in the preparation process.
The end result is a truly remarkable specimen.
