Isurus sp. (Mako shark)
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. D056 is an upper jaw tooth. Authenticity guaranteed.
D056 SIZE: 7/16"
Note - 6 new Sumatran Mako teeth added in January 2018. Link to Sumatran teeth.
