Three-toothed Puffers

 
 Family Triodontidae
Genus Triodon (Cuvier, 1829)
Triodon antiquus (Leriche, 1905)

Age - Eocene - Occurrence - ?

Triodon antiquus is commonly known as the three-toothed puffer, unlike most puffer fish which have four teeth T. antiquus has three. Pufferfish have teeth fused together into a beak-like structure worked by powerful jaw muscles that are strong enough to crush shells and crabs. The only example of T. antiquus Iíve found is the single tooth of the lower jaw.


 

Triodon macropterus is the only living species in the genus Triodon.
