【摘要】 埃迪卡拉纪晚期高家山生物群的多门类骨骼化石组合,在后生动物起源及早期生命演化方面具有极其重要的意义。在对高家山生物群中的研究中,新发现了大量的磷酸盐化球状化石,包括单体球类、二分球类及三分球类等。这些磷酸盐化球状化石在形态结构方面与"瓮安生物群"、"宽川铺生物群"中报道的球状化石有着一定的相似性。高家山生物群中球状化石新材料的发现不仅丰富了高家山生物群的多样性,为早期生命演化提供了可靠的材料,也揭示了前寒武纪-寒武纪生物之间可能存在着一定的连续性。更多还原

【Abstract】 The Gaojiashan biota in the late Ediacaran period consists of multiple skeletal organisms that is of great significance in the origin and early life evolution of metazoans. With the profound research of the Gaojiashan biota, a large number phosphated spheroid fossils are discovered, including unicellular spheres, 2-cell and 3-cell spheres.These phosphatase spheroidal fossils have certain similarities in morphological structure to the spheroidal fossils reported in the "Weng~,an Biota" and "Kuanchuanpu Biota". The discovery of new spheroidal fossils in the Gaojiashan biota not only enriches the diversity of the Gaojiashan biota, but provides reliable materials for early life evolution and enhances the evolutionary continuity of the Precambrian-Cambrian transition.更多还原
