长期以来，有两个主要困难阻碍了对古代全矿化微生物的研究：（1）以微米级分辨率准确记录其三维形态； (2) 直接表征其分子结构组成。在这里，我们介绍一种古生物学新技术，即满足这两种需求的三维拉曼图像，这是一种非侵入式、非破坏性的技术，可以提供数据，以微米级分辨率原位准确、客观地表征全矿化微生物及其相关基质的形态和分子结构组成。这项新技术的应用可以提供任何其他方式无法提供的有关微生物化石的形态、埋藏学和保存保真度的信息。
Two major difficulties have long hindered studies of ancient permineralized micro-organisms: (1) accurate documentation of their three-dimensional morphology at micron-scale resolution; and (2) direct characterization of their molecular-structural composition. Here we introduce a technique new to palaeobiology, the three-dimensional Raman imagery that meets both of these needs, which is a nonintrusive, nondestructive technique that can provide data by which to accurately and objectively characterize, in situ and at micron-scale resolution, the morphology and molecular-structural composition of permineralized micro-organisms and their associated matrices. Application of this new technique can provide information about the morphology, taphonomy and fidelity of preservation of fossil micro-organisms unavailable by any other means.
