According to Brusatte "et al." (2011), "Dryptosaurus" can be distinguished based on the following characteristics: the combination of a reduced humerus (humerus: femur ratio = 0.375) and a large hand (phalanx I-1:femur ratio = 0.200), the strong mediolateral expansion of the ischial tubercle, which is approximately 1.7 times as wide as the shaft immediately distally, the presence of an ovoid fossa on the medial surface of the femoral shaft immediately proximal to the medial condyle, which is demarcated anteriorly by the mesiodistal crest and demarcated medially by a novel crest, the presence of a proximomedially trending ridge on the anterior surface of the fibula immediately proximal to the iliofibularis tubercle, the lip on the lateral surface of the lateral condyle of the astragalus is prominent and is overlapping the proximal surface of the calcaneum, metatarsal IV is observed with a flat shaft proximally, resulting in a semiovoid cross section that is much wider mediolaterally than it is long anteroposteriorly.
