Bone lesions in a Late Pleistocene assemblage of the insular deer Candiacervus sp.II from Liko cave (Crete, Greece)

摘要

Candiacervus sp.II is one of the deer species that inhabited the island of Crete during the Late Pleistocene. The species evolved on the island under a prolonged period of isolation and, as a consequence, developed a high degree of endemism. Fossils of this species have been discovered at many Cretan sites, including Lilco cave (an attritional accumulation of several thousand fossils). In this paper, we present the results of a systematic analysis of the prevalence and anatomical distribution of bone lesions of Candiacervus sp.II, from that cave. We identified one metapodial with a healed fracture and nine (various) specimens with moderate to severe degenerative lesions of osteoarthritis. The lesions were evaluated macroscopically and radiographically, and they were classified as traumatic or degenerative. Degenerative lesions that affected adult individuals had prevalence rates below 5% and were attributed to environmental or nutritional causes. Representative bones were sampled for histological evaluation, to provide essential baseline data on possible underlying disorders. The aims of this study are to provide evidence for bone disease contributing to species morbidity, and to shed new light on causes and potential palaeoecological significance. (C) 2016 Elsevier Inc.
