21. Eurypterids
    Erie Canal construction (~1900) revealed the presence of prehistoric animals-eurypterids-at Pittsford, New York. The fossils were discovered by Clifton Sarle (1903) and he described new species of arthropods including one named after the town of Pittsford, viz. Eurypterus pittsfordensis.

    Extractions:    Accompanying illustrations in the exhibit, Prehistoric Pittsford, show the morphological features of two common eurypterid forms ( Hughmilleria and Eurypterus .  Note the head region having a carapace with two eyes present.  Often, the eyes are located somewhat centrally as in Eurypterus ; sometimes marginally as in Hughmilleria .  Behind the head region are several body segments (tergites) ending in a spiked 'tail', the telson.  Many other features are noted in the drawings  EURYPTERID STRUCTURE    Two distinctly different eurypterids were common during Silurian time as represented by the fossils found in the rocks of the Lower Salina Group of western New York.  Both are described in the exhibit "Prehistorid Pittsford." The slender Hughmilleria socialis Sarle is the most common form found in the Pittsford Member and may have been  actively swimming in nearby rivers.
