ABSTRACT

In this work, the stratigraphy of Arroyo Trujillo (Cantillana, Sevilla) site, in the Guadalquivir Basin, is updated and the fossil bivalve community is studied. A new stratigraphic section has been made, differentiating four sections encompassed in the Transgressive Basal Complex of the upper Tortonian. One hundred and thirty two bivalves have been identiﬁed, 10 out of them are mentioned for the ﬁrst time in the Iberian Peninsula. The distribution of these species in different stratigraphic sections is analysed. The community of bivalves has been compared with other sites, corroborating the similarity with Cacela site (Portugal). The fossil content suggests normal salinity conditions and subtropical-tropical climate.

Key words: Guadalquivir Basin, Arroyo Trujillo, upper Tortonian, Transgressive Basal Complex (BTC), Bivalvia.
