 Description:
Elegant example of a member of the Order Phacopida, Superfamily Acastoidea
with many fine details present. While most frequently known in the
trade as “Big Eye”, this one is actually Erbenochile,
and has just become commercially available in limited quantities.
The most diagnostic features of this taxon are the high “eye-towers”.
Fortey and Chatterton described Erbenochile erbeni in September 2003
from a single commercially- prepared specimen, and it created a stampede
among collectors. The “wrap around” eyes gave a good panoramic
view of the trilobite’s environment, allowing it to keep alert
for predator and prey alike. Since fish had recently evolved true
jaws, any advantage a prey species could derive would place it at
an advantage. This one has been prepared with the genal and axial
spines all free standing, quite an achievement from such hard matrix.
The rarity and difficulty in preparation are what commands a high
price. |
