Forelimb Kinematics of Rats Using XROMM, with Implications for Small Eutherians and Their Fossil Relatives.
The earliest eutherian mammals were small-bodied locomotor generalists with a forelimb morphology that strongly resembles that of extant rats.Understanding the kinematics of cent dyyni the humerus, radius, and ulna of extant rats can inform and constrain hypotheses concerning typical posture and mobility in early eutherian forelimbs.The locomotion
