[EN]Some fragments of Chelonian from the Vallesian (Upper Miocene) of Valles de Fuentidue?a, in the Segovia Province (Spain), are described in this paper. One fragment, belonging to the frontal part of a plastron, has been classified as Testudo sp. (nov. sp.?) (aff. catalaunica Bataller, 1926), because the validity of the genera Protestudo Ckhikvadze, 1970 is under discussion. The characteristic features correspond probably to a new species, but as the specimen belongs to a young tortoise -it presents hio-hipoplastral phontanella-, such classification could not be correct. Another specimen found in the same deposit shows the existence of Testudo sp. with two suprapygal plates. Some other fragments, also belonging to young individuals -they have open pleuro-peripheral phontanellas- correspond to a species next to Testudo catalaunica. In any case, the available data do not permit to affirm whether these fragments belong to the same species or not. In a different level of deposit, fragments of an adult Testudo sp. (aff. catalaunica) and of gigantic tortoises [?Geochelone bolivari (Hern?ndez Pacheco, 1917)] have been also found.
[ES]Se describen fragmentos de Quelonios procedentes del Vallesiense de Los Valles de Fuentidue?a (Segovia). Uno de ellos consiste en la parte delantera de un plastron, que se ha clasificado como Testudo sp. (nov. sp?) (aff. catalaunica Bataller, 1926). Se discute sobre la posibilidad de inclusi?n en el g?nero Protestudo CKHIKVADGE, 1970. Los caracteres del individuo son propios de una especie nueva, pero estaba en edad juvenil -presenta fontanela abdominal-, por lo que su clasificaci?n como tal no hubiera sido correcta. Otro ejemplar demuestra la presencia en el yacimiento de Testudo sp. con dos placas suprapigales. Varios fragmentos m?s corresponden a individuo/s en edad juvenil, puesto que muestran fontanelas pleuro-periferales abiertas. Se les atribuye a una especie af?n a Testudo catalaunica. Con los datos de que se dispone no se puede saber si todos los fragmentos hallados corresponden a la misma especie. En otra zona del mismo yacimiento se han encontrado fragmentos de otro individuo adulto de Testudo sp. (aff. catalaunica) y de tortugas gigantescas, del tama?o de "Geochelone" bolivari (Hern?ndez Pacheco).
