|  This
is an enrolled specimen of Griffithides bufo, a rare member of the
Trilobite
Order Proetida, Family Proetidae. Coming from the Osagean Stage
deposits of Crawfordsville, Indiana, this trilobite is a member
of the last surviving order of trilobites, the Proetida. It is found
in these same deposits made famous by the wonderful crinoids found
there. There is also a well-preserved brachiopod on the same matrix,
making for a most uncommon association plaque.
