Isurus sp. (Mako shark)

    In stock

    A rare Mako shark tooth from Sumatra, Indonesia. These teeth appear to be juvenile Isurus desori teeth (narrow crown) and are scarce in the Sumatran deposit. They were deposited in the Telisa formation - a shallow marine environment during the middle Miocene (approx. 15 million years ago.) A very unique collector's tooth. D054 is the lower jaw tooth on the right. Authenticity guaranteed.

    D054 (Right)       SIZE: 7/16"

    Note - 5 new Sumatran Mako teeth added in January 2018.       Link to Sumatran teeth.


    Mako sharks are large Mackerel sharks from the Lamnidaefamily. They inhabit temperate waters worldwide. Most species are know for their great speed. Ther Sumatran Mako teeth appear to be from juvenile Isurus desori.

    This collection represents a rare and very unusual collection of Miocene fossil shark teeth from the island of Sumatra, Indonesia. Few collectors have these teeth and even fewer have had the opportunity to collect this site as I did!
