The aim of this study is to provide a detailed anatomical characterisation of three exhumed mandibles of Patagonian huemul (<jats:italic>Hippocamelus bisulcus<\/jats:italic>) through three\u2010dimensional reconstructions obtained from computed tomography data and semi\u2010automatic segmentation, documenting their distinctive features. The findings revealed distinctive features in the mandible, consistent with the browsing habits of herbivores, such as a robust coronoid process, a wide and deep pterygoid fossa, a significantly lower mandibular condyle compared to other deer species and a unique configuration of the mandibular canal with a curved caudal portion and a straight rostral portion. These anatomical adaptations are likely related to the species' feeding habits and behaviour. The study also addressed the challenges of researching an endangered species, given that access to biological material is restricted by strict regulations in Chile and Argentina. These restrictions limited the available sample size and hindered the acquisition of additional specimens, which could affect the generalisation of the results. Despite these limitations, the research provides valuable anatomical insights that are fundamental for the biology, clinical practice and management of specimens. In conclusion, the mandibles of both juvenile and adult Patagonian huemul demonstrate distinctive features characteristic of browsing herbivores. The findings can serve as a basis for future comparative studies on mandibular anatomy and function in this endangered deer species as well as in other herbivorous deer.<\/jats:p>","DOI":"10.1111\/ahe.13108","type":"journal-article","created":{"date-parts":[[2024,10,9]],"date-time":"2024-10-09T10:28:54Z","timestamp":1728469734000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Anatomical and Computed Tomography Study of the Mandible of the Patagonian Huemul (<i>Hippocamelus bisulcus<\/i>): Ecological and Clinical Insights"],"prefix":"10.1111","volume":"53","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3778-6812","authenticated-orcid":false,"given":"Samuel","family":"N\u00fa\u00f1ez\u2010Cook","sequence":"first","affiliation":[{"name":"Laboratory of Animal &amp; Experimental Morphology, Institute of Biology, Faculty of Sciences Pontificia Universidad Cat\u00f3lica de Valpara\u00edso  Valpara\u00edso Chile"},{"name":"MSc Program in Morphological Sciences Universidad de La Frontera  Temuco Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fernando","family":"Vidal","sequence":"additional","affiliation":[{"name":"Fauna Andina Wildlife Conservation and Management Center  Villarrica Chile"},{"name":"IUCN, Deer Specialist Group  Apple Valley Minnesota USA"},{"name":"IUCN, Conservation Planning Specialist Group  Apple Valley Minnesota USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2273-0904","authenticated-orcid":false,"given":"Paulo","family":"Salinas","sequence":"additional","affiliation":[{"name":"Laboratory of Animal &amp; Experimental Morphology, Institute of Biology, Faculty of Sciences Pontificia Universidad Cat\u00f3lica de Valpara\u00edso  Valpara\u00edso Chile"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,10,9]]},"reference":[{"issue":"2","key":"e_1_2_10_2_1","first-page":"241","article-title":"Morfolog\u00eda cr\u00e1neo\u2010mandibular en mam\u00edferos herb\u00edvoros: macrop\u00f3didos (Metatheria, Diprotodontia, Macropodidae) y c\u00e1vidos (Eutheria, Rodentia, Hystricomorpha) como un caso de estudio","volume":"26","author":"\u00c1lvarez A.","year":"2019","journal-title":"Mastozoologia Neotropical"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1469\u20107998.1993.tb05351.x"},{"key":"e_1_2_10_4_1","first-page":"252","volume-title":"Cirug\u00eda oral y maxilofacial en animales de compa\u00f1\u00eda","author":"Ascaso F.
