本文描述了阿根廷里奥内格罗省巴塔哥尼亚中中新世Collon Curd组中一个新的、巨大的鸟化石（Aves：Cariamae）的解剖结构。新的phorusrhacid是已知的单一标本，包括一个几乎完整的头骨与跗跖骨和足趾骨。新化石是已知最大的phorusrhacid，其形态更类似于传统上归类在phorusrhacines内的分类群。它的头骨是迄今为止在大型骨鼻龙中保存最完好的，提供了大量以前未知的解剖学信息，并表明基于它们较小的亲戚重建巨型骨鼻龙的头骨是没有根据的。
The anatomy of a new, enormous phorusrhacid (Aves: Cariamae) from the Middle Miocene Collon Curd Formation of northwestern Patagonia (Rio Negro province, Argentina) is described. The new phorusrhacid is known by a single specimen that consists of a nearly complete skull associated with a tarsometatarsus and a pedal phalanx. The new fossil is the largest known phorusrhacid and its morphology resembles more that of taxa traditionally grouped within phorusrhacines. Its skull-by far the best preserved among large phorusrhacids-provides a great deal of previously unknown anatomical information and indicates that reconstructions of the skull of gigantic phorusrhacids based on their smaller relatives are unwarranted.
