The cranial characters for the phylogenetic analysis were checked against the illustrated specimens, the postcranial characters of the Muller and Tsuji (2007) analysis against the well-preserved postcrania
of PIN 158/4 and PIN 162, and the braincase characters against the descriptions of Ivakhnenko (1979) for the elements that were not preserved in the cranial material studied for this analysis.
For both individuals, determination of age, sex, and pathology was carried out as well as documentation of morphological variation of nonmetric traits of the dentition and skeleton, along with metric measurements of the crania and postcrania
Measurements were made on all available postcrania
after Martin & Saller (1957).
