This project will apply a new transformative technology, X-ray micro computed tomography, to the study of Early Palaeozoic (530-300 million year old) radiolarian microfossils. It is expected that this will allow, for the first time, non-destructive examination to elucidate the internal skeletal architecture of these fossils that is critical to understanding their evolution. Computer reconstruction of three-dimensional images will reveal details upon which an understanding of early phylogenetic relationships within this phylum can be developed. This in turn will allow realisation of the full biostratigraphic potential of this important long-ranging group of marine protozoans that commonly occur in great abundance in deep marine sedimentary rocks.

该项目将应用一种新的革命性技术——x射线微计算机断层扫描技术，研究早古生代（5.3 -3亿年前）放射虫微化石。预计这将首次允许非破坏性检查来阐明这些化石的内部骨骼结构，这对了解它们的进化至关重要。三维图像的计算机重建将揭示对该门早期系统发育关系的理解可以发展的细节。这反过来又将使这一重要的长期海洋原生动物群的全部生物地层潜力得以实现，它们通常大量存在于深海沉积岩中。
