TABLE 1. Summary of Ameghinornithidae fossil remains. Note that the holotype specimen of Strigogyps dubius was destroyed (cited as "numéro 2" in the collection of the Bayerische Staatssammlung für Paläontologie und Historische Geologie, Munich; Gaillard, 1908, p.39).
TABLE 2. Size comparison of Ameghinornithidae tibiotarsi (in mm). Anatomical abbreviations: plT, preserved length of tibiotarsus; lwT, lateromedial width of tibiotarsus; cdT, craniocaudal depth of tibiotarsus. Estimated measurements and measurements of preserved dimensions are denoted by "*" and measurements missing owing to damage are denoted by "-". Data from Strigogyps species were compiled from Lambrecht (1935), Peters (1987, 2007) and Mayr (2005, 2007). Measurements of S. dubius are from a cast of the holotype specimen (PQ 1073) curated in the collection of the Musée Guimet d'Histoire Naturelle de Lyon (France) and provided by Peters (2007).
