“…in the mandible were similar to skull shape results. In terms of shape variation distributions, Bardhoka and İvesi sheep skulls comparing with other Balkan specimens have been detected differences in the shape variations [18]. In this study, mandible shapes were examined and it was found that İvesi breed showed wider shape variation, while Bardhoka breed showed narrower shape variation.…”

“…By using the distance between two points in anatomical formations with the traditional morphometry method, we reach length, depth and angle data [18,33]. On the other hand, geometric morphometry (GM), is a method that provides more comprehensive data based on the analysis of all geometric data taken from anatomical points, curves and outlines, two-or three-dimensional Cartesian coordinates [3,5].…”

“…In order to reveal the differences among groups and to analyze the group structure in multivariate data, Discriminant Function Analysis is used if there are two groups in the data set, and Canonical Variate Analysis is used if there are more groups [25]. Accordingly, geometric morphometric analysis is a more useful and appropriate method to explain the shape variations [18]. In recent years, various studies using geometric morphometry method in veterinary anatomy have revealed morphometric differences and shape variations among species, breeds and between sexes [16,18,20,26,36].…”

In countries that have animal husbandry tradition and are developing this, it is impossible not to underline the different local breeds. There is anatomically significant morphological and morphometric variability among these breeds, which differ from one region to another. In this study, geometric morphometry was performed in order to examine the shape variation of the mandible and to reveal the shape variations due to breed diversity in the Bardhoka (Kosova), Țurcana (Romania) and İvesi (Turkey) breed sheep. A total of 40 (10 Bardhoka, 10 Țurcana, 20 İvesi) mandibles were used and were examined shape differences for these three breeds. 2D images of the mandibles were analyzed from the lateral view 9 landmarks were used. Average shape and shape variations of the mandible were obtained for all samples. Mandible showed significant shape variation among sheep breeds and the results were statistically significant. According to the results, among the three sheep breeds in the study, the İvesi breed has the widest mandible shape distribution. While İvesi and Țurcana show a wider distribution in shape variation; The Bardhoka breed expressed a more limited variation. It can be noticed that all three breeds are morphologically and morphometrically different from each other. Bardhoka and İvesi breeds were the most different from each other in this study (p < 0.0001). It is thought that the obtained findings will contribute to future geometric morphometry studies with ruminant mandible samples.

BackgroundWith the development of technology, 2D images have left their place for 3D models. The 3D modelling technique is widely used in plastic surgery, orthopaedic surgery, neurosurgery, traumatology, dentistry and medical education. The skull is important in terms of containing the starting parts of systems with vital functions.ObjectiveThe aim of the study is to reveal the difference between male and female and other species by 3D (three‐dimensional) modelling and craniometric measurements of Romanov heads.MethodsIn our study, skulls of Romanov sheep (10 females and 10 males) older than 1‐year‐old were used. The heads of Romanov sheep were scanned with computed tomography and modelled in 3D.Results and ConclusionsIn the study, it was determined that there was a statistically significant difference between male and female sheep in terms of the largest nose length, facial width, molar row length, viscerocranium length, and foramen magnum height parameters (p < 0.05). It was determined that the greatest width of the foramen magnum measurement parameter and the skull index showed statistically significant differences between the genders at the p < 0.01 level. No statistically significant difference was found in other measurements (p > 0.05). The data obtained as a result of the study will help in the racial discrimination and classification of bones obtained from zoo archaeological excavations.
