Associated Fauna
A great variety of marine forms are associated with the Bertie Group Eurypterid Faunas. On this page, I will add examples of the other types of fossils recovered from the eurypterid beds of New York and Ontario, Canada. Some of the fossils found, especially in the Bertie Beds, in- clude gastropods, cephalopods, brachiopods (including Lingula and Orbiculoidea), at least one conulariid and problematica.
Highspired gastropod (1 1/2 inch long) found in the Eurypterus lacustris Fauna of the Williamsville Wl. (Bertie Group) of the Niagara Peninsula, Ontario, Canada by Tod Clements of Brockport, New York. Specimen No. 031002-4. Highspired gastropods are common at this locality, usually occurring in clusters. Most are very small, but this specimen in unusually large.  Below this gastropod in a very fragmented piece of eurypterid integument.

If one doesn't observe all of the features associated with eurypterid horizons--the sedimentary structures and lithology, and all of the associated fauna, then there is no resason to study eurypterids.  Anyone can go into the literature and write a paper on eurypterids--but unless you are in the field persistently--why bother.

CEPHALOPODS
AT LEFT: a cephalopod. Cephalopods are a characteristic element of the Eurypterus lacustris Fauna.  Both straight and coiled specimens have been frequently encoun- tered. This specimen: 033095-14 from Williamsville Wl. of Ontario, Canada.
AT RIGHT: a scorpion from the Late Silurian Phelps Waterlime near Cedarville, New York. We currently know of three different species from the world-famous Eurypterus remipes Fauna of the Fiddlers Green Fm., Bertie Group of Eastern New York State.
