Significant differences between sprawling taxa unable to rotate the radius about the ulna, parasagittal taxa able to rotate the radius about the ulna (to differing degrees), and extinct non-avian dinosaurs based on angle of curvature with a Bonferroni-corrected p-value. Blank spaces represent non-significant differences between groups.

^* p<0.00178; Sp = sprawled, P = parasagittal, C = ceratopsian, NH = non-hadrosaurid ornithopod, H = hadrosaurid, Thy = thyreophoran, Sa = sauropodomorph, The = theropod.
