Florida, Montbrook, late Miocene, heron, Ardeidae, new taxaAbstract
From the recently discovered Montbrook locality, Levy County, Florida (late Miocene; late Hemphillian land mammal age), a complete coracoid and nearly complete scapula represent a large heron that we name Taphophoyx hodgei new genus and species. While the phylogenetic affinities of T. hodgei are not well resolved, the tiger-herons Tigrisoma spp. or boat-billed heron Cochlearius cochlearius (both Neotropical) may be the closest living relative(s) of Taphophoyx, based in large part on several shared characters of the facies articularis clavicularis and facies articularis humeralis. Nevertheless, the coracoid of Taphophoyx has a uniquely prominent facies articularis humeralis and a uniquely sterno-ventral surface of corpus coracoidei. All 21 taxa of birds recorded thus far from Montbrook (mostly aquatic forms such as swans, ducks, geese, grebes, cormorants, ibises, sandpipers, etc.) probably represent extinct species, although Taphophoyx hodgei is the only one assigned to an extinct genus.
