Cuatro formas de Artiodactyla (Mammalia) del yacimiento eoceno de Mazaterón (Cuenca del Duero, Soria, España)

Abstract

Four forms of Artiodactyla (Mammalia) of the eocene bed of Mazaterón (Duero basin, Soria, Spain)

In this work is made a preliminary study of the Artiodactyla (Mammalia) material of the Mazaterón bed (Middle Eocene-Upper Eocene, MP 16-17, Duero Bassin, Spain). Four forms, belonging to 3 families are identified: cf. Dacrytherium, cf. Leptotheridium (bod Dacrytheriidae), cf. Dichodon(Xiphodontidae), bod families normals in the Middle Eocene-Upper Eocene transit, and Anoplotheriinae indet. (Anoplot heriidae), very rares in the european beds until the La Ddbruge (MP 18) level. Dacrytheriidae and Anoplotheriidae are first named in the Eocene of the Duero Bassin.
