Summary: Carnivorans are known for their exceptional backbone mobility, enabling them to excel in fast running and hunting. Jaw-seizing predators like hyenas and canids have elongated cervical regions and higher cervical mobility. Other carnivoran families have shorter cervical regions but higher neck flexibility. Lumbar flexibility is important for carnivorans, with differences in mobility among species.

Summary: Aprotodon is an extinct genus of the family Rhinocerotidae with distinctive features like wide mandibular symphysis and prominent second low incisors. A well-preserved mandible fossil from the Early Miocene in the Lanzhou Basin, Gansu Province, China, shows elongated and curved tusk-like incisors, supporting attribution to A. lanzhouensis.

Summary: Quantified coat pattern dissimilarity provides a visible surface for individual animal traceability to populations. Using geometric morphometrics, the study determined the uniqueness of stripe patterns of Cape mountain zebra, finding significant shape variation and individual uniqueness in the population. This approach could be useful for phenotypic monitoring and identification.

Summary: In this study, the earliest representative of Elasmotherium, discovered in Dingbian County, Shaanxi, northwestern China, is reported and named Elasmotherium primigenium. Elasmotherium primigenium shows a unique mosaic of primitive and derived features, making it more primitive than other known species of Elasmotherium.

Summary: This study investigated the muscular and osteological anatomy of tapirs and their relatives using gross dissection and digital imaging. The presence and position of the supraspinous ridge on the scapula may be a robust phylogenetic character for reconstructing relationships within tapiroids.

Summary: Low back pain is associated with mobility impairments in the spine, pelvis, and hip. This study aimed to assess the effects of fascia tissue manipulation through lumbodorsal skin displacement (SKD) on the range of motion (ROM) in healthy subjects. The results showed that SKD had a significant effect on flexion and extension ROM, with the effect depending on the location and displacement direction. The intertester and intratester reliability of SKD were also found to be good.

Summary: This study used an osteometry-based method to calculate the available range of motion in presacral intervertebral joints in artiodactyls, finding that the cervical region is the most mobile area, while the thoracic region is characterized by the greatest amplitudes of axial rotation.

Summary: Newly discovered fossil remains of Rhinocerotidae from the early Late Miocene in Myanmar provide important insights into the evolutionary history of rhinoceros in Southeast Asia. The fossils, including teeth, maxillae, and mandibles, were assigned to three taxa: Brachypotherium perimense, 'Brachypotherium' fatehjangense, and Rhinoceros sp. This discovery represents the oldest fossil records for Rhinoceros in Southeast Asia and suggests faunal exchange between Myanmar and the Indian subcontinent during the late Neogene.

Summary: This study is the first comprehensive analysis of lumbosacral joint mobility in even-toed ungulates, revealing that the lumbosacral joint is more mobile in sagittal bending than the lumbar joint and its range of motion is closely related to body mass and running form.

Summary: The study focused on biomechanical changes after vertebral column resection and posterior unilateral vertebral resection and reconstruction for old vertebral compression fractures with kyphosis. Results showed a decrease in range of motion in all fixed models, with varying stress levels at different points within the internal fixation system, which may help explain potential failure and migration issues.

Summary: Prosantorhinusgermanicus is a small, short-legged rhino from the Miocene of Sandelzhausen, Germany, with a unique modification in the articulation of its carpal bones. Some individuals have additional articulation facets that restrict flexion in the mid-carpal joint, potentially supporting the idea of P.germanicus as a dwarfed rhinoceros species and a semi-aquatic lifestyle.

Summary: This study developed a mechanistic approach for calculating available range of motion (aROM) in presacral intervertebral joints based on osteometry. Trigonometric formulae were used for aROM calculation, and it was found that facet-specific formulas resulted in greater accuracy compared to formulas based on the spine as a whole or different spine regions. The facet-specific formulas were particularly effective in calculating aROM in axial rotation (AR).

Summary: This study used cementum and dentine increment analysis to investigate the remains of cave bears from European Russia, the Urals and the Caucasus. The results showed that the majority of the cave bear remains belonged to adult and old animals, and the damage to dental crowns may be related to age, conflict between males, and food abrasion. Furthermore, the increment analysis indicated that the cave bears visited the caves year-round. These findings raise new questions in the study of the ecology of cave bears.

Summary: In this paper, the tooth microwear of extinct Crocuta hyenas from the Late Pleistocene period was studied to analyze their feeding habits and ecological differences. The microwear patterns of these hyenas were found to resemble those of extant spotted hyenas, but differed from other hyena species. There were similarities in microwear patterns between adult and juvenile individuals.

Summary: This study describes the discovery of a woolly rhinoceros nasal horn in the permafrost of Yakutia, which shows that the shape of the base of the nasal horn corresponds well to the shape of the nasal rugosity area. It suggests that the narrower shape of the nasal horn base in previously found specimens may have been caused by secondary damage after burial.
