中文摘要: 本项目拟对湘西寒武纪的奥斯坦型保存化石进行系统分类学和个体发育学研究,发现更多的Skracarids, Phosphatocopids标本,深化 Phosphatocpids的个体发育和甲壳类动物附肢模式的早期演化研究;并且发现其它类型的奥斯坦型保存化石。同时对软躯体的形态特征进行定量分析和形态功能学探讨。运用同步加速器X-射线层析显微技术(SRXTM),发现奥斯坦型保存化石的内脏器官。探索化石胚胎和奥斯坦型保存化石在全世界独一无二共存的埋藏机制。

英文摘要: This proposal plans to make the research on the systematics and the ontogeny of Orsten-type fossils from the Cambrian in western Hunan Province.To recover more specimens of skracarids and phosphatocopids, deepening the research on the ontogeny of Phosphatocopids and the early evolution of the segment patterning of crustaceans and to find other kinds of Orsten-type fossils. Furthermore, we will focus on the morphometry and the functional morphology of the characters of soft-bodied fossils. Using the technique of synchrotron X-ray tomographic microscopy (SRXTM), to explore the possible preservation of the internal organs in Orsten-type fossils. To explore the taphonomic mechanism of the worldwide unique co-existence of fossilized embryos and Orsten-type arthropods.
