English: Facial characteristics of MH1. (a) Diagrammatic representation of the individual components of the intranasal region of MH1 based on synchrotron data (See also Figs S3 and S4). A step-like (similar to continuous-discrete classification of ref. 4) relationship between premaxilla and nasal cavity floor can be identified in MH1 as well as a lack of contact of the premaxilla with the vomer. (b) Reconstructed facial growth remodeling map of the face of MH1. Bone deposition is indicated by magenta whereas bone resorption is indicated in blue. Resorption can be observed along various portions of the lower face most predominantly along the alveolar region. (c) Reconstructed facial map of Australopithecus (Au. afarensis + Au. africanus) superimposed on Taung’s face (reproduced from ref. 12) based on the analysis of the sub-adult specimens LH 2, AL 333-105, LH 21, Sts 2, Stw 59, Taung, Sts 24, Sts 57, MLD 2 and Sts 52.
