In this Article, the ‘S1-3’ label was misplaced in Fig. 1c, and the legend to Fig. 2c should state ‘Labial view’ rather than ‘Lingual view’. In addition, in Supplementary Figs 2d and 3c, the yellow and red labels for upper teeth were the wrong way round, and the legend to Supplementary Fig. 2 should state ‘labial’ rather than ‘lingual’ view, and from the ‘right side of skull in labial view’ rather than ‘left side of skull in lingual view’. These changes have been corrected in the HTML and PDF versions of the original paper and its Supplementary Information.
