dc.description.abstract |
The Plio-Pleistocene karstic sedimentary deposits of Sterkfontein Cave, South Africa, yielded numerous fossil primate
specimens embedded in blocks of indurated breccia, including the partial cercopithecoid cranium labelled STS
1039. Because the surrounding matrix masks most of its morphology, the specimen remains taxonomically undetermined.
While the use of X-ray microtomography did not allow extracting any structural information about the specimen,
we experimented a new investigative technique based on neutron microtomography. Using this innovative
approach, we successfully virtually extracted, reconstructed in 3D and quantitatively assessed the preserved dentognathic
structural morphology of STS 1039, including details of its postcanine maxillary dentition. Following comparative
analyses with a number of Plio-Pleistocene and extant cercopithecoid taxa, we tentatively propose a taxonomic
attribution to the taxon Cercopithecoides williamsi. Our experience highlights the remarkable potential of this novel
imaging method to extract diagnostic information and to identify the fossil remains embedded in hard breccia from
the South African hominin-bearing cave sites. |
