The second-most common element of the Hughmilleria
socialis
Fauna is the relatively large eurypterid, Eurypterus
pittsfordensis
. At left is an example showing the carapace
and a few eurypterid tergites preserved in a weathered-out
piece of Pittsford F. Apparently, it is the action of ground-
water that produces the yellow-orange staining that com-
monly seems to occur at this stratigraphic interval.
Remains of
E. pittsfordensis appear to occur throughout
the Pittsford Member of the Vernon Formation in this area
but also appear to be more concentrated in the upper
layers, just below Pittsford E.,  in a thin interval of black
shale.
