μCTや各種分析機器を用いた化石種と現生種における口腔領域の硬組織解析

抄録

  X-ray CT (CT: X-ray computed tomography) and X-ray μCT (μCT: X-ray micro-computed tomography) are characterized by the fact that the sample to be studied can be analyzed non-destructively without cutting or slicing. Here, the research results on the tissue structure of the jawbone of Eusthenopteron foodi (Devonian, Canadian), modern sperm whale teeth and Miocene horse molars, Pliocene marine mammal penile bones, human premolar cementum and jawbones and teeth of Mosasaurus sp. (Cretaceous, Morocco) are exhibited. Using various methods such as X-ray CT, X-ray μCT, micro-Raman spectroscopy, and FE-SEM, the detailed internal structure, the composition and constituent crystals of hard tissue can be analyzed in a more multidimensional manner.
