Hind limb musculature and habits of a Paleocene multituberculate. American Museum novitates ; no. 333

Abstract

"1. The femur of Eucosmodon was held in a nearly horizontal position, pointing outward and slightly forward and downward. 2. The restoration of the pelvic musculature shows it to have a degree of differentiation similar to that of other mammals. 3. The details of muscular morphology and function are characteristically different from those of other mammals or of reptiles. 4. The pelvic musculature, in agreement with all other known anatomical and environmental features, indicates an arboreal mode of life"--P. 18.
