Moluscos y microvertebrados del Pleistoceno de las terrazas del río Tajo en Toledo y Fuentidueña de Tajo (España Central)

The study of the terraces and its associated faunas from the areas of Toledo and Fuentidueña de Tajo in the Valley of the Tagus River, mainly from a palaeoenvironmental point of view, has been made in this work. Six new sites of fossil microvertebrates and fossil molluscs were found when this work w...
