Rare Ditomopyge olsoni Trilobites
Order Proetida, Superfamily Proetoidea, Family Proetidae
Time: Pennsylvanian (Carboniferous)
inch): each trilobite is 14 mm
Staunton Formationm, Coal Run, Indiana
Trilobites from the Pennsylvanian are generally rare, trilobites
from this locality are specifically rare, and Ditomopyge olsoni
is rare among those. This is a very attractive association of two
that are fully inflated and three dimensional. Unfortunately, the
site were these were found is no longer accessible for collecting.
Order Proetida comprised the last surviving trilobites, finally
meeting extinction themselves at the end of the Permain Period.
