Paleopathological Changes in Animal Bones from Croatian Archaeological Sites from Prehistory to New Modern Period.

A special part of archaeology, so-called archaeozoopathology or veterinary paleopathology is dedicated to studies of paleopathological changes in animal remains and contributes to the knowledge of ancient veterinary medicine and the history of diseases. In our study, we analyze paleopathological changes determined by gross observation and diagnostic imaging in the animal material originating from eight archaeological sites in Croatia. A standard archaeozoological analysis was carried out and specimens with visually detected macrostructural changes were radiographed. In total, 50 animal remains with altered macrostructure were identified in the archaeozoological material excavated from 2010 to 2022 at eight archaeological sites in Croatia. According to the taxonomic analysis, most of the bones with macrostructural changes originated from cattle (N = 27, 54% of the total number of bones with macrostructural changes), followed by the bones of small ruminants (N = 12, 24%) and pigs (N = 8, 16%). The horse, carnivore and chicken were represented with one bone each (2%). Radiological examination showed that three samples (6%) had a regular bone macrostructure, i.e., no pathological changes were visible upon radiological examination. The majority (64%) of pathologically altered bones are a consequence of keeping/working, followed by traumatic causes (20%). Changes in the oral cavity were found in 10% of specimens. Our study showed that gross examination will continue to be the primary method for the identification of pathologically altered remains in archaeozoological material. However, diagnostic imaging techniques such as radiography should be implemented to confirm or exclude suspected alterations and to help the classification of the specimen by etiology.

Early dispersal of domestic horses into the Great Plains and northern Rockies.

The horse is central to many Indigenous cultures across the American Southwest and the Great Plains. However, when and how horses were first integrated into Indigenous lifeways remain contentious, with extant models derived largely from colonial records. We conducted an interdisciplinary study of an assemblage of historic archaeological horse remains, integrating genomic, isotopic, radiocarbon, and paleopathological evidence. Archaeological and modern North American horses show strong Iberian genetic affinities, with later influx from British sources, but no Viking proximity. Horses rapidly spread from the south into the northern Rockies and central plains by the first half of the 17th century CE, likely through Indigenous exchange networks. They were deeply integrated into Indigenous societies before the arrival of 18th-century European observers, as reflected in herd management, ceremonial practices, and culture.

Anatomical variations of the thoracic duct in the dog.

Anatomical variations can be frequently found in the lymphatic system, which is also true for the shape and course of the thoracic duct (ductus thoracicus), the biggest lymph vessel in the body. From 2012 to 2019, the thoracic duct was successfully dissected in 43 dog carcasses that were used in the anatomy course at the Faculty of Veterinary Medicine, University of Zagreb. The thoracic duct originated from the cranial border of the cisterna chyli as one lymph vessel in 36 dogs (83.7%), as two vessels in six dogs (14%) and as three vessels in one dog (2.3%). We divided the observed thoracic duct variations into six groups according to their anatomical similarities. Considering the specific embryonic development, we can conclude that all observed variations are the result of minor deviations from the standard ontogenesis. However, the importance of thoracic duct variations is significant in surgical procedures done in the thoracic cavity to prevent or cure the chylothorax. Since this research showed variations in 39 out of 43 dogs (90.7%) throughout the whole course of the thoracic duct, great care must be taken while performing the ligation or embolization of the thoracic duct.

An archeozoological analysis of teeth of lower jaw of pigs coming from the Kostolac culture (3,250-3,000 B.C.), originating from Vucedol, including comparison with recent.

An investigation has been made within the expertise regarding teeth of 10 left halves of mandibles of recent sows as well as teeth of 18 pig mandibles originating from Kostolac culture (3,250-3,000 B.C.) from Vucedol archaeological location. TWS (Tooth Wear Stage) has been determined at all molars, according to Grant method and a corresponding numerical equivalent has been added, so MWS (Mandibular Wear Stage) has been obtained by summing up the above. On the basis of these values and ranges of MWS, an approximate age at the time of death has been determined for each unit. All the recent units have been older than 17 months, while the age of Kostolac units has come out to be between 14 and 17 months.

The importance and representation of teeth in archaeozoological material.

Archaeologists, in most cases, neglect animal bones and teeth, which present common material on archaeological sites. Analysis of archaeozoological material from Vucedol (Baden culture) and prehistoric cave site Vela spila on Korcula, has been applied to stress the importance of that material (especially single animal teeth) in archaeozoological samples. It is obvious that a higher percentage of single teeth influence the number of identified animal species on particular sites. One species were identified only by teeth. For the reconstruction of the environment and behavior of ancient peoples, every evidence obtained from sites is important, and because of that sieving must be part of every excavation.
