The aim of the study is to analyse the auricula of human foetus using geometric morphometric methods based on the foetal age groups and, thus, to determine the presence of shape differences. For this purpose, the foetuses having a gestational age of 23-40 weeks were divided in three groups based on intrauterine gestational age and analysed. After performing photography, landmarking and dataset formation stages for geometric morphometric analysis, the principal component, and discriminant and regression analyses were made. The first principal component accounted for 26.461% of the total shape difference based on foetal age. The most apparent shape changes were observed on helix (superior), crus helicis, tragus and antitragus points. Consequently, the variations concentrated especially around cavum concha.
