Resumen:
The caracaras represent a characteristic faunal element of the Neotropics. Recently, a verylarge fossil species Caracara major from late Pleistocene of Uruguay was considered the largestknown falconid. In the present contribution we describe a larger specimen belonging to a Caracaraform from the late Pleistocene of the Buenos Aires province. The body mass estimation of this specimenclearly exceeds that of living caracaras species and, represents the largest known falconid (lowestbody mass estimation nearly of 4500 grams). The diversification and extinction of large?sized caracarasmay be correlated with the abundance of very large mammals, which may provide abundant largecarcasses as a food resource, in the late Pleistocene-early Holocene.
