[EN] Las Caldas Cave is an exceptional site, placed in the West of the Cantabric Region (Asturias). It has a complete magdalenian stratigraphycal sequence, with plentiful and typical lithic, osseous and Portable Art series. In this article we study three plates with rock carving of stepping fauna, such as reindeer, mammoth and rhynoceros, which were found in the Middle Magdalenian base. These three plates allow us to review and extend the chronology of these representations, scarced in Palaeolithic Cantabric art, estimated until the date. Furthermore, they also force us to question the chronology which is commonly accepted for some magdalenian techniques and conventionalisms (bichromy, figures made of dots, striated engraving).

[ES] La Cueva de Las Caldas (Asturias) es un yacimiento excepcional, situado en el Occidente de de la Region Cant?brica. Posee una completa secuencia estratigr?fica magdaleniense, con abundantes y t?picas series l?ticas, ?seas y de Arte mueble. En este art?culo se estudian tres plaquitas procedentes de la base del Magdaleniense medio, con grabados de fauna est?pica: reno, mamut y rinoceronte lanudo. Ello permite revisar y ampliar la cronolog?a estimada hasta la fecha para estas representaciones, muy raras en el Arte paleol?tico cant?brico. Adem?s, obligan a cuestionarse tambi?n la cronolog?a com?nmente admitida para algunas t?cnicas y convencionalismos magdalenienses (bicrom?a, tamponado, grabado-estriado).
