Abstract:
:The Regourdou 1 partial skeleton was found in 1957 in level IV of the eponymous site located in Montignac-sur-Vézère (Dordogne, France) and until now it has been only partially published. The ongoing revision of the faunal remains from the site has yielded additional fossils that pertain to this skeleton. Here we study the vertebral column of this individual, providing for the first time detailed descriptions for all of the fossils and reassessing the anatomical position of all of the fragments. The vertebral column of Regourdou 1 is one of the most complete in the Neandertal fossil record with at least 20 pre-sacral vertebrae (seven cervicals, nine thoracic and four lumbars), a partial sacrum and a fragmentary first coccygeal vertebra. When compared with modern humans, the vertebrae of Regourdou 1 display significant metric differences, and fit well within the range of Neandertal variability. A preliminary analysis of the most complete thoracic vertebrae of this individual indicates that Neandertals displayed significant differences from modern humans in the thoracic spine, which adds to the differences already observed in the cervical and lumbar regions. Finally, we have also observed mild signs of osteoarthrosis, albeit to a lower degree of that present in other Neandertals such as La Chapelle-aux-Saints, La Ferrassie 1 or Shanidar 3. This is consistent with the younger adult age for Regourdou 1.
