At the end of the 19th century, E.J. Marey and E. Muybridge separately invented instruments which permit to study the musculoskeletal movements of the big mammals, in particular the horse. Observing the musculoskeletal of small mammals is complicated, because their movements are fastest and their fur hides their limbs. The tachycineradiography, a technique which associates high-speed cinematography to radiography, permits to discover the whole geometry of their skeleton, and to analyze their fast movements.
