In contrast to normal morphometric measurements, geometric morphometry is a method that can explain the differences and variations on the x-y coordinates of the specified points on a 2D plane. In this method, two-dimensional samples, such as pictures or x-rays, are used. The study aims to investigate the right os coxae of 23 adults (12 males, 11 females) horses geometrically. Photographs were taken from each sample at 120 centimeters distance and landmarks were made on these samples. 13 determining landmarks were used on os coxae. Medial endpoint of the narrowest section of the body of ilium and medial endpoint of ischial spine points were found to be statistically significant in terms of female and male distinction (P < 0.001). It was seen that the remaining points in the ventrolateral section did not have a statistically significant difference in gender discrimination. However, the difference between the genders in the ventral endpoint of coxal tuber and midpoint of coxal tuber in the dorsolateral section was statistically significant (P < 0.001). The difference between females and males is visually indicated using the morphology program. In females, it was observed that the points in the inner region are more lateral than males. Gender analysis studies can be conducted on materials such as bone using the morphometric results obtained as a result of such modeling studies.
