ABOVE: Eurypterus pittsfordensis (left the cast in dark mudstone, right the mold impressed in hard waterlime). CIURCA 121306-1
Note that most of the carbonized integument is preserved on the cast. The width of the carapace, at base, is 7.5 cm. Had the cast
weathered away, the impression in the waterlime, a type of fine-grained dolostone and much more resistant to weathering, would have

and eurypterid fragments
Pterygotid Ramus CIURCA 122306-1 ENLARGED
ABOVE: Part of the ramus of a pterygotid - note some of the teeth that are preserved, most facing forward. The Tastings Site has provided
a few specimens of pterygotid remains, usually telsons and an occasional ramus. The pterygotids were, obviously, carnivores and it
seems likely that Hughmilleria, so prolifically present in the Pittsford fauna, was its prey. In recent years, a lot more has been learned
about the pterygotids of the Vernon Formation and publications are forthcoming. This is such a fascinating group of animals to study.
