Paracrax
Sign in to saveParacrax ("near curassow") is a genus of extinct North American flightless birds, possibly related to modern seriemas and the extinct terror birds. Part of Bathornithidae (though some analysis recover it as closer to the living seriemas instead, or possibly entirely out of Cariamiformes), it is a specialised member of this group, being cursorial carnivores much like their South American cousins, some species attaining massive sizes.

== Discovery == Paracrax antiqua is the genus type species. The type specimen, YPM 537, was collected in Weld County, Colorado, in 1871 by Othniel Charles Marsh, which identified it as a sort of turkey. It was posteriorly referred to Cracidae by Pierce Brodkorb, before its identity as a bathornithid came to light. Material previously identified as a cormorant, "Phalacrocorax/Oligocrocorax" mediterraneus, was posteriorly identified as P. antiqua remains.
