“…In our study, the degree of dorsal separation of the skulls by race was limited. Demiraslan et al (2021), in their geometric morphometric study on the mandible of Honamlı and Hair goats, reported that Hair goats showed a very distinct gender difference compared to Honamlı goats, and that male goats were clearly clustered compared to female goats in terms of race factor. In our study, the degree of dorsal separation of skulls by breed was limited and the most prominent clustering was seen in Honamlı skulls in females and Honamlı and Saanen skulls in males.…”

The aim of the study was to analyze the dorsal aspect of the skulls of Honamli, Hair, Kilis and Saanen goats by geometric morphometric method. A total of 48 adult goat skulls, 6 male and 6 female, were used for each breed. After the skulls were photographed dorsally, 10 homologous landmarks were marked. As a result of our study, the degree of dorsal separation of the skulls according to sex was found to be limited. Nevertheless, significant separation was seen in the Honamli skulls of females and in the Honamli and Saanen skulls of males. This information may serve as a reference for the skull remains of ruminants.

“…However, thanks to geometric analysis, it could be interpreted in terms of shape. To determine the sexual dimorphism by geometric analysis in dogs, goats, and sheep, information was obtained in terms of geometric morphometry [21,[32][33][34].…”

The study investigated whether there is a morphological difference between the shape of the female and male quail’s skulls. For this purpose, 18 female and 21 male quails were used. After the skulls were obtained, their photographs were taken, and geometric analysis was performed. Dorsal (14 landmarks), caudal (8 landmarks), and ventral (13 landmarks) images of skulls were evaluated. As a result of the Principal Component Analysis (PCA), 28 principal components (PCs) were obtained for dorsal view, 16 PCs for caudal view, and 26 PCs for ventral view. PC1 (41.206%) for the caudal aspect explained the highest shape variation in terms of sex. It was seen that PC1 for dorsal view explained 33.046% and PC1 for ventral view explained 34.495% shape variation. For the dorsal view, the orbital pit of males was found to be deeper than females. The foramen magnum was narrower in female skulls. The lateral borders of the neurocranium were more pointed upwards in males. On ventral view, it was seen that male individuals had a wider skull in shape. Geometrically, it was determined that the male and female distinction was the best in the dorsal view. According to the dorsal view, only one male individual was found to be in the female group, and all other male individuals were completely separated from the females. After the dorsal view, the best distinction was seen ventrally. In the caudal examination, sexual discrimination was not fully seen. In this study, shape differences in quail’s skulls were examined between sexes, and shape differences were revealed geometrically. In addition to traditional morphometry studies, it is thought that geometric analysis studies will add a useful perspective to the literature.

“…In recent years, numerous studies have been conducted to reveal the shape differences of cranium or mandible via the geometric morphometric method in different species such as wolf (11), dog (23), quail (30), turkey (10), sheep (6), goat (5), and deer (17). However, no study comparing two different sheep breeds via semilandmarks was encountered.…”

The aim of this study is to determine whether or not the breed and sex factors have an effect on the shape in the mandibles of Hamdani and Awassi sheep. A total of 31 mandibles were used. The samples were analyzed via geometric morphometric methods by using semilandmark. In the study, it was determined that the primary principal component accounted for 36.52% of the total shape difference. According to principal component analysis, samples were clustered significantly in terms of breed; whereas, they were not clustered in terms of sex. In terms of the primary principal component, the places where the shape differences were concentrated were the attachment sites of teeth to the mandible, between the second molar and ramus mandible, the processus coronoideus and the angulus mandible. Mandible of Hamdani sheep had a higher body than the mandible of Awassi sheep. Mandible of male sheep was more voluminous than mandible of female sheep, especially in the body area. Consequently, it is thought that the data obtained as a result of the study would serve as a reference for the ruminant mandible remains obtained from archaeological excavations.
