What is "podilymbus"

Podilymbus is a genus of birds in the Podicipedidae family, containing the extinct Atitlán grebe (Podilymbus gigas) and the pied-billed grebe (Podilymbus podiceps). The genus name is derived from Latin Podilymbus, a contraction of podicipes ("feet at the buttocks", from podici-, "rump-" + pes, "foot")—the origin of the name of the grebe order—and Ancient Greek kolymbos, "diver".

There are also several prehistoric taxa of Podilymbus described from fossil remains:

• Podilymbus majusculus (Late Pliocene of Wisconsin)
• Podilymbus wetmorei (Late Pleistocene of Florida)
• Podilymbus podiceps magnus - a paleosubspecies of the pied-billed grebe of uncertain validity.
