We review in detail the published fossil record of turtles from Sardinia and, in addition, we document previously undescribed specimens for the first time. Among these undescribed specimens, is the oldest occurrence of Testudo hermanni on the island, from the Early Pleistocene of Monte Tuttavista. The turtle fossil record in Sardinia goes back to the Eocene and comprises 18 different taxa, pertaining to 6 lineages: Podocnemididae, Cheloniidae, Emydidae, Geoemydidae, Testudinidae, and Trionychidae. Remarkable is the occurrence of Eocene pleurodires, whose presence is in agreement with the Oligo-Miocene rifting of the Corso-Sardinian block. Interestingly, the fossil record provides evidence for the presence in the island of both Testudo hermanni and Emys orbicularis during the Pleistocene although according to molecular data the extant populations of these two taxa were introduced in recent times. Finally, a large ungual phalanx from the Middle–Late Pleistocene Monte San Giovanni bone breccia testifies the occurrence of a giant tortoise in the Quaternary terrestrial ecosystem of Sardinia.

Abstract

We review in detail the published fossil record of turtles from Sardinia and, in addition, we document previously undescribed specimens for the first time. Among these undescribed specimens, is the oldest occurrence of Testudo hermanni on the island, from the Early Pleistocene of Monte Tuttavista. The turtle fossil record in Sardinia goes back to the Eocene and comprises 18 different taxa, pertaining to 6 lineages: Podocnemididae, Cheloniidae, Emydidae, Geoemydidae, Testudinidae, and Trionychidae. Remarkable is the occurrence of Eocene pleurodires, whose presence is in agreement with the Oligo-Miocene rifting of the Corso-Sardinian block. Interestingly, the fossil record provides evidence for the presence in the island of both Testudo hermanni and Emys orbicularis during the Pleistocene although according to molecular data the extant populations of these two taxa were introduced in recent times. Finally, a large ungual phalanx from the Middle–Late Pleistocene Monte San Giovanni bone breccia testifies the occurrence of a giant tortoise in the Quaternary terrestrial ecosystem of Sardinia.
