“虚拟古生物学”需要使用计算方法来辅助化石的三维（3-D）可视化和分析，并已成为研究生命历史的有力方法。三维成像技术使人们对植物化石、无脊椎动物和脊椎动物化石以及微体化石和遗迹化石的解剖结构了解甚少或以前未知的解剖结构得到了比以前更详细的描述，并且适用于广泛的保存类型和标本大小（表1）。这些方法包括非破坏性的高分辨率扫描技术，如传统的X射线显微断层扫描和基于同步加速器的X射线断层扫描。此外，形式和功能可以通过计算机模型的定量分析（例如有限元分析）进行严格的研究。查看此表：表1适用于化石的三维成像技术的比较，以及它们对不同材料的适用性。有关这些技术的全面综述，请参见萨顿等人（2014）。在2012年，我们共同主持了一个专题会议虚拟古生物学：化石形式和功能的计算机辅助分析。
‘Virtual paleontology' entails the use of computational methods to assist in the three-dimensional (3-D) visualization and analysis of fossils, and has emerged as a powerful approach for research on the history of life. Three-dimensional imaging techniques allow poorly understood or previously unknown anatomies of fossil plants, invertebrates, and vertebrates, as well as microfossils and trace fossils, to be described in much greater detail than formerly possible, and are applicable to a wide range of preservation types and specimen sizes (Table 1). These methods include non-destructive high-resolution scanning technologies such as conventional X-ray micro-tomography and synchrotron-based X-ray tomography. In addition, form and function can be rigorously investigated through quantitative analysis of computer models, for example finite-element analysis.

(2014) for a comprehensive review of the techniques. In 2012, we co-chaired a topical session on Virtual paleontology: computer-aided analysis of fossil form and function …
