Nuevos datos sobre las tortugas del Puerto de la Cadena (Mioceno superior de Murcia) New data on the turtles from Puerto de la Cadena (Late Miocene of Murcia)

La Alberca is a fossil site of the Late Miocene of the area of Puerto de la Cadena (Murcia, Spain). A mammalian fauna with relatively high diversity has been identified there. However, the information about the turtles was, until now, very limited. Abundant turtles, assigned to Testudinidae, have been recognized in other sites of Puerto de la Cadena. The study of the turtles from La Alberca allows to identify a large taxon of testudinid turtle, assigned to Cheirogaster cf. bolivari, and a aquatic turtle, assigned to Trionychinae. This finding broadens the stratigraphic distribution of the group in the Iberian Peninsula. In addition, it constitutes the first reference to Trionychinae in the southern half of Spain. The review of unpublished material allows to identify Trionychinae in other sites of Puerto de la Cadena.
