mm = 1 inch): Trilobite is 55 mm long by 45 mm wide (including spines)

Coming from the nearly half billion year old Lower Ordovician
deposits of the Wolchow River Region of Russia, this is Boedaspis
ensifer. I termed the last one the “Emperror of Trilobites” due
to its stunning presence. With rarity and expenditure of countless
hours of prep time comes a concomitant price, one that has stayed
relatively constant for the decade in which they have been available.
As a member of the family Odontopleuridae it shares a relationship
with the spiny Devonian trilobites Ceratonurus, Dicranurus and
Koneprusia, but far outclasses them all. The first example of
this taxon I had displayed only the scimitar-shaped occipital
spines preserved free of matrix, this one goes farther to demonstrate
the craft of the foremost paleontological preparation laboratory
of Russia showing no less than the next dozen major spines also
prepared freestanding. This one took in excess of 150 hours to
prepare. Restoration is minimal, and is primarily related to
the fact that the major spines were removed to facilitate preparation,
and then reattached when the underlying exoskeleton was exposed.
It comes wired into a wooden shipping box. I have attached a
couple of photos of it safely installed ready for shipping. I
used primarily preshipment photos to show this one off. With
all the spines it would take the steady hands of a bomb disposal
expert to free it from the wires securing it, and I thought discretion
would be the better part of valor in that regards. Nevertheless
you can see what a stunning specimen it is from all aspects.
