Material. Proximal end of right tibia ( TTUP 12537X) from the Headquarters South locality ( MOTT 3898); distal end of right femur (WTAMU-V-8301) from the "lower Sunday Canyon" Site ( Figure 4 View FIGURE 4 ).
Description and remarks. The proximal surface of TTU-P12537X is triangular and the three sides are almost equal in length ( Figure 9 View FIGURE 9 ). The cnemial crest is small but distinct, and its tip is slightly projected laterally. Posterior condyles are aligned, not pronounced and separated by a very shallow cleft. The lateral condyle is ventrally deflected, as diagnostic of Dromomeron ( Nesbitt et al., 2009) . Even though the medial condyle is obliterated, the posterior condyles seem to be aligned and sub-equal in size, a character that is more comparable to D. romeri (see Irmis et al., 2007b, figure 2; Nesbitt et al., 2009, figure 4).
The slender shaft of WTAMU-V-8301 significantly widens distally with a distinct ridge on the anteromedial side that establishes its affinity to Dromomeron romeri ( Irmis et al., 2007b) ( Figure 10 View FIGURE 10 ). The distal end is much larger mediolaterally than anteroposteriorly. Condyles are small and gracile as noted for D. romeri ( Nesbitt et al., 2009) . Medial and fibular condyles are well separated by the intercondylar groove.
