“…Dayan et al. ( 2022 ) detected the greatest breadth of the foramen magnum parameter as 20.48 ± 0.64 mm in males and 20.77 ± 0.60 mm in females in their study on Hamdani sheep, while Parés‐Casanova et al. reported the same parameter as 20.00 ± 2.00 mm in a study conducted on Rasquera White goats in 2014.…”

“…In addition, statistical difference was determined between sexes in terms of these two parameters ( p < 0.05). It was determined that the facial breadth parameter was smaller than South Karaman sheep breed (Özüdoğru et al., 2022 ) and larger than Hamdani sheep breed (Dayan et al., 2022 ). The length of the molar row value was lower in South Karaman (Özüdoğru et al., 2022 ), Morkaraman, Tuj sheep breeds (Özcan et al., 2010 ) and Bardhoka sheep breeds (Gündemir et al., 2020 ).…”

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.

The skull is a vitally important complex structure formed by the combination of many bones. Craniometric studies are performed with various imaging methods to determine morphometric characteristics in animals. One of these methods is radiography. In our study, skulls of 14 Hamdani sheep, 20 Siirt‐coloured mohair goats and 20 Romanov sheep breeds were used. Skull sections were taken with a computed tomography device and saved in DICOM format. Nine separate measurements and six index calculations were made from the images. In the study, firstly, the gender difference was ignored and the similarities and differences between the species were recorded. In addition, gender differences were determined statistically, without making any distinction between species. Correlation analysis was performed to compare measurement parameters between animal species. As a result of the study, the highest skull length (SL) and cranial length (CL) values were determined in the Siirt‐coloured mohair goat. It was determined that the difference between Romanov sheep and Siirt‐coloured mohair goat in CL parameter was not statistically significant (p > 0.05). In addition, a statistically significant difference was observed between the Romanov sheep breed and the Hamdani sheep breed (p < 0.01). The external length of the cranium (ELC) measurement parameter was found to have a statistically significant difference in three animals (p < 0.01). According to the results of the correlation analysis, the highest correlation value was determined between cranial width (CW) and CL parameters (r = 0.920). When the species difference was ignored, and the statistical difference of the internal height of the cranium (IHC) parameter was found to be significant between female and male animals (p < 0.05). In addition, it was determined that SL, CW and internal cranium index (ICI) parameters had a significant difference depending on sex (p < 0.01). It is foreseen that the obtained data can be used in sciences such as zoo archaeology, anatomy, surgery and forensic medicine.

BackgroundMorphometric measurements help to understand the skull morphology in different animal species, detect skull deformations and figure out their causes.ObjectivesThe aim of this study is to make a three‐dimensional (3D) modelling of the badger skull using computed tomography, to show its anatomical structures and to reveal the morphometric measurement values.MethodsSkull measurements were carried out using a digital calliper at 27 measurement points based on metric measurement points. After the scanned images were stored in Digital Imaging and Communications in Medicine format, they were transferred to MIMICS 20.1 (The Materialize Group) programme and 3D models the skulls were created. The surface area and volume values of the skulls were calculated on these models.ResultsThe volume and surface area parameters were expressed as mean ± SE. Four different indices were calculated using osteometric measurements. Statistical analyses were made by determining the mean value and standard deviation of the examined properties and the correlation coefficients among these properties. In the metric measurement points taken as a basis, the longest measurement in the skulls was the total length and its mean value was 124.60 ± 0.64 mm. The shortest measurement was the breadth dorsal to the external auditory meatus, and its mean value was 6.75 ± 0.24 mm.ConclusionsConsequently, statistical differences in the craniometric values of badgers’ skulls were determined by using CT and 3D modelling software. In addition, it was concluded that the badger skull can be easily distinguished from other carnivore species by carrying out morphometric measurements.
