灭绝分类群的功能和生态推断一直是人们感兴趣的主题，因为它是了解物种进化历史的基础。在这项研究中，我们使用定量的方法来调查的运动行为Simocyon batalleri，一个关键的分类群有关的ailurid家庭。要做到这一点，我们使用3D表面几何形态测量的方法对现存的参考样本的前肢的三个长骨。接下来，我们测试了S的运动策略。batalleri使用留一交叉验证线性判别分析。结果表明，S. batalleri被包括在现存的鼬类物种的形态空间中。然而，前肢的每块骨头似乎显示出不同的功能信号，这表明推断化石的生活方式或运动行为可能很困难，并且取决于所研究的骨头。这突出了研究的重要性，在可能的情况下，最大限度的骨骼元素，能够对灭绝物种的生活方式作出强有力的推断。最后，我们的结果表明，S。batalleri可能比以前提出的更树栖。
Inferences of function and ecology in extinct taxa have long been a subject of interest because it is fundamental to understand the evolutionary history of species. In this study, we use a quantitative approach to investigate the locomotor behaviour of Simocyon batalleri, a key taxon related to the ailurid family. To do so, we use 3D surface geometric morphometric approaches on the three long bones of the forelimb of an extant reference sample. Next, we test the locomotor strategy of S. batalleri using a leave-one-out cross-validated linear discriminant analysis. Our results show that S. batalleri is included in the morphospace of the living species of musteloids. However, each bone of the forelimb appears to show a different functional signal suggesting that inferring the lifestyle or locomotor behaviour of fossils can be difficult and dependent on the bone investigated. This highlights the importance of studying, where possible, a maximum of skeletal elements to be able to make robust inferences on the lifestyle of extinct species. Finally, our results suggest that S. batalleri may be more arboreal than previously suggested.
