Abstract Geometric morphometrics allows the acquisition and analysis of shape coordinates representing the geometry of a specimen and is not limited to obtaining linear data such as height or width which are not enough precise compared with geometric data. The fronto-nasal profile variation of various bovine breeds was analysed using this method. The analysis consisted of three steps: collection of primary data, obtaining shape variables, and statistical analysis. The primary data were obtained from 15 homologous landmarks and two homologous semi-landmarks. These points were taken on the lateral view of the skull of 19 adult individuals representative of each breed. The results obtained by applying standard statistical tests revealed that the cranial profile lacks a differentiating size and shape configuration (absence of fronto-nasal profile correlation with skull shape). Additionally, both variables were not cross-correlated
