Drum Fish

 
 Family Sciaenidae
Genus Pogonias (Lacepède, 1801)
Pogonias sp.

Age - Miocene to present - Occurrence - Common


The most common fossil remains of the Pogonias sp. in New Jersey are the individual pharyngeal teeth located in the back of the throat, which allowed
them to pick-up, crush, and sort hard prey such as mollusks and crustaceans. The shape is of these teeth is somewhat irregular, ranging from circular to a rounded square. The teeth are small ( 2 - 5 mm) and similar to the pharyngeal teeth of the Tautoga.
