Abstract

Egretta subfluvia, n. sp. is described from a nearly complete right tarsometatarsus from the Withlacoochee River 4A local fauna. It is a small species of Egretta and is the first paleospecies of this genus. Examination of the fossil mammals from the Withlacoochee River 4A local fauna documents the North American Land Mammal Age of this local fauna as late early Hemphillian. Other specimens from the late Miocene and early Pliocene of Florida show the existence of unidentifiable species of Ardea, Egretta, and Ardeola. The coracoid and distal end of tarsometatarsus of Ardea polkensis are reported for the first time.
