Description

    SHEER-JAWED SHARK TOOTH
    Edestus sp.
    Carboniferous
    Illinois

    A most unusual shark; unlike modern sharks, the Edestus did not shed teeth nor grow teeth in rows, but rather it possessed a single row of teeth in each jaw that continuously grew from the back of the jaw. Eventually they had a set of curved jaws with serrated teeth that might have functioned like garden sheers. Edestus teeth and jaws are extremely rare compared to those of other sharks because of their age, over 300 million years ago; this present specimen features part of the jaw with a large partial tooth bearing impressively robust serrations. The entire specimen measures 3 x 1 ΒΌ inches.


    Estimate: $350 - $500.
