Biology:Eoscatophagus

From HandWiki

Eoscatophagus ("dawn Scatophagus") is an extinct genus of marine ray-finned fish, in the family Scatophagidae, known from the Eocene.[1] It contains a single species, E. frontalis, known from the Monte Bolca site of Italy.[2]

It is the earliest scatophagid known from the fossil record. It was originally erroneously identified by Volta (1796) as a specimen of the spotted scat (Scatophagus argus, then known as Chaetodon argus) itself, before being described as its own species within Scatophagus by Agassiz (1839).[3] It was moved to its own genus, Eoscatophagus, in 1999.[4]

Fossil specimen

As the earliest known member of the Scatophagidae, it is often used for calibrating phylogenies of marine fish evolution.[5][6]
