    Eurypterus lacustris,
    Bertie Gr., Williamsville Fm. Buffalo area, Western New York
    Although they look similar to today’s lobsters, the
    Eurypterid’s
    closest living relatives are actually horseshoe crabs, spiders, and scorpions. Their bodies are divided into three parts: the prosoma, or head; the opisthosoma (body); and the telson (tail). The paddle-like limbs were used for swimming in a probable up and down rowing motion.  The
    Eurypterus lacustris
    averaged at 6 to 9 inches in length,  This is very similar to the
    Eurypterus remipes,
    however its eyes are placed farther back on its hard upper shell, or carapace.
    This fossil is about as large as they got. This specimen measures;
    length 9” when measured along the curve of the spine, 8.5” x 8.5”, 4.5 lb. solid piece of matrix.
