Dr. Miller – Publication in the Journal of Human Evolution
by Jeff Nichols
Congratulations to Dr. Ellen Miller! The article entitled “Morphological affinities of a fossil ulna (KNM-WS 65401) from Buluk, Kenya” was recently published in the Journal of Evolution.
A primate proximal ulna (KNM-WS 65401) was recovered as a surface find at Buluk during the 2013 field season. This specimen represents one of the few well-preserved primate postcranial remains from Buluk amenable to quantitative analyses, and thus has the potential to shed light on primate locomotor and ecological diversity at this late Early Miocene site.
From left to right, photographs of KNM-WS 65401 in lateral, medial, and anterior views, followed by high-resolution surface scans of KNM-WS 65401 bearing landmarks used in this study in lateral, medial, and anterior views. Scale bar (in mm) applicable to all lateral, medial, and anterior views. Proximal view (far right) is enlarged to show landmarks and is not to scale. All landmarks were included in analyses of the 19-landmark data set, whereas the landmarks in red typeface were removed for the 14-landmark data set.
Principal component analysis (PC1 and PC2) of extant primate species mean Procrustes coordinates in the 19-landmark sample, with KNM-WS 65401. Warped meshes (Macaca nemestrina) showing morphological changes along each principal component. For each set, views from top to bottom: anterior, lateral, and proximal.
