---|---|---|
S. J. Nesbitt et al. 2009 | Differs from Dromomeron romeri in possessing a distinct ridge for the attachment of the M. caudifemoralis longus (=4th trochanter), the presence of an anterior trochanter and trochanteric shelf, robust proximal and distal ends of the femora, the intercondylar groove of the distal femur is reduced to a slit in larger specimens (possible autapomorphy), and the lack of an anteromedial concavity on the distal end of the tibia. |
