A new record of fossil sirenians from the Miocene of Sardinia (Italy).
Bollettino della Società Paleontologica Italiana 59(2): 5 tabs. 5 figs. Sept. 2020 (publ. online, July 21, 2020).
–ABSTRACT: The first diagnostic sirenian material from Sardinia is reported and the fossil record of Miocene Sardinian sirenians is reviewed through an updated geological and stratigraphic framework. The new specimens are referred to Metaxytherium cf. M. krahuletzi Deperet, 1895, indicating the diffusion of the species into the mid-southern Tethys. We also state that the other specimens from the early middle Miocene previously found on the island should be assigned to the same species. We regard the holotype of Metaxytherium lovisati Capellini, 1886 as not diagnostic and consider it a nomen dubium. This conclusion is consistent with the taxonomic analysis given by Sorbi (2008) which winnowed the nominal taxa into four Miocene and Pliocene species.
