数字解剖是一种相对较新的技术，使科学家能够更好地了解脊椎动物解剖学。它可用于以易于访问的方式快速传播详细的三维信息，从而减少破坏性的传统解剖的需要。在这里，我们展示了澳大利亚河口鳄鱼（Crocodylus porosus）阑尾肌肉组织的数字解剖结果。更好地了解 C. porosus 中这个迄今为止鲜为人知的系统非常重要，不仅因为它将扩大对鳄鱼运动的研究，而且因为它有可能为恐龙类群的肌肉重建提供信息。描述了前肢和后肢的肌肉，并包括基于 CT 和 MRI 扫描以及新鲜组织解剖的三维交互模型。我们发现了鳄鱼目中的 C. porosus 和其他类群的肌肉组织排列存在差异。在前肢，差异仅限于肱三头肌内侧长肌的单一起源肌腱。对于后肢，注意到周围头数量的减少以及髂腓肌和腓肠肌外肌的起点和插入位置的变化。
Digital dissection is a relatively new technique that has enabled scientists to gain a better understanding of vertebrate anatomy. It can be used to rapidly disseminate detailed, three-dimensional information in an easily accessible manner that reduces the need for destructive, traditional dissections. Here we present the results of a digital dissection on the appendicular musculature of the Australian estuarine crocodile (Crocodylus porosus). A better understanding of this until now poorly known system in C. porosus is important, not only because it will expand research into crocodilian locomotion, but because of its potential to inform muscle reconstructions in dinosaur taxa. Muscles of the forelimb and hindlimb are described and three-dimensional interactive models are included based on CT and MRI scans as well as fresh-tissue dissections. Differences in the arrangement of musculature between C. porosus and other groups within the Crocodylia were found. In the forelimb, differences are restricted to a single tendon of origin for triceps longus medialis. For the hindlimb, a reduction in the number of heads of ambiens was noted as well as changes to the location of origin and insertion for iliofibularis and gastrocnemius externus.
