Résumé

The caviomorph rodents of South America and the small forest-dwelling ruminants of Africa have a distinct evolutionary history. However, they are similar in size and weight, and share anatomical features normally associated with running: long limbs, a narrow thorax, small or non-existent clavicles, etc. The use of a high-speed video camera combined with an x-ray machine for tachycineradiography, in which movement is slowed down to 1/20th of normal speed to produce 500 frames a second, makes it possible to view the characteristics of their skeletons and their different paces (trot and gallop).
