摘要:

X射线计算机断层扫描技术可以在不破坏遗迹标本的情况下重现标本内部结构,为客观解释遗迹化石的形态、结构、埋藏学特征及其形成环境提供现实依据。通过X射线计算机断层扫描技术所呈现的高分辨率无损三维生物遗迹图像,可以清晰直观地识别生物遗迹的形态结构特征,全方位解析现代生物的潜穴、行为生态学特征及其与环境的相互作用,进而分析其行为习性、生态习性并类比遗迹化石,为遗迹化石的识别及形态分类和生态分类提供了技术支持,能够为遗迹化石在古地理、古生态环境的重建方面提供更加精确的指示作用,并对之前使用传统研究方法难以界定的遗迹化石重新进行研究,解决遗留的历史问题。该技术应用于生物遗迹识别方面的研究,将形成新的认识,产生新的理论。

Abstract:

X-ray Computed Tomography provides realistic basis for the interpretation of the morphology, structure, taphonomy and related environmental characteristics of the biogenic sedimentary structures. X-ray Computed Tomography can assist non-sample-destructive reconstruction the internal structure, and generates high-resolution three-dimensional (3D) bioglyph images. The technique can enhance the analyze of the morphological and structural characteristics of biogenic sedimentary structures. This technoque can then be used to study biological behaviors, ecological habits and the analogy of trace fossils. Meanwhile, it supports the identification and morphological classification and ecological classification of trace fossils, which provides a more accurate indication of the reconstruction of paleogeographic and palaeoecological environment. In addition, the undefined trace fossils left by conventional analytical techniques could be re-analyzed. The application of X-ray computed tomography in biogenic structure identification will produce new understanding and new ideas. It will also promote the X-ray computed tomography in ichnological applications.

Key words: ichnology, trace fossil identification, X-ray computed tomography, non-sample-destructive 3D imaging, biogenic sedimentary structure
