An unexpected Scalopini mole (Talpidae, Mammalia) from the Pliocene of Europe sheds light on the phylogeny of talpids

| Resumo: | The Pliocene Konservat-Lagerstätten maar lake site of Camp dels Ninots (NE Iberian Peninsula) has recently delivered a partial skeleton of a mole (family Talpidae) with many elements in anatomical connection. At a first glance, molar and humerus size, geological time interval, and geographical location suggested that this specimen could correspond to Talpa minor. However, after some mechanical preparation of the clay block (matrix removal, consolidation, and cleaning) and a micro-CT scan, this excellently preserved specimen turned out to be an unknown species to science. The resulting 3D models of this new form, Vulcanoscaptor ninoti gen. et sp. nov., revealed some peculiar morphological traits in teeth, mandible, and postcranial elements, which according to the phylogenetic analysis carried out, would allocate this new species within the tribe Scalopini. This is surprising, because the closest relatives of the new species within this tribe live nowadays in North America, and only some related taxa had been previously reported in the Oligocene and Miocene fossil record from Europe. The postcranial construction of this specimen reveals a highly fossorial lifestyle supported by a complex forelimb structure. How such a specialized digging animal reached the maar lake sediments where it was finally preserved is still to be solved. Some hypotheses consider swimming abilities for this extinct species. Alternatively, this specimen could be the remaining portions of a floated or scavenged carcass whose remains fell into the lake and reached the anoxic bottom. |
