在陕西省宁强县石钟沟剖面的早寒武世宽川铺组细晶至中晶磷质石灰岩以及泥晶磷质石灰岩中,通过酸解处理得到了大量化石胚胎Olivooides,及其孵化后的幼年个体,未成年个体和成年体化石(后二者即Punctatus).通过同步加速器X射线层析扫描显微(Synchrotron X-ray Tomographic Microscopy)技术,用Amira4.0软件复原了Olivooides和Punctatus三维的内部结构.对它们的星状结构进行了统计和形态功能学分析,认为此结构是为了适应快速固着生活而产生的,可能用于分泌黏液.对Punctatus的内部结构进行了探讨,认为部分标本中出现的卵状结构并非卵或者其他生物本身的结构,而是一种产生在生物体埋葬之后,矿化之前或矿化过程中的埋葬结构.Punctatus的内部结构由横板组成,可能类似于珊瑚中的横板,软躯体生长在横板上.
In the Early Cambrian Kuanchuanpu Formation fine-grained phosphogypsum-limestone and clay-graded phosphorous limestone in the Shizonggou Section, Ningqiang County, Shaanxi Province, a large number of Olivooides were obtained by acid-solution treatment and their young after hatching Individuals, juveniles and adult fossils (the latter two, Punctatus). The inner three-dimensional Olivooides and Punctatus were restored by Amira 4.0 using synchrotron X-ray Tomographic Microscopy Structure.According to the statistical and morphological functional analysis of their stellate structure, this structure is believed to be produced by rapid fixation and may be used to secrete mucus.The internal structure of Punctatus was discussed, and some of the specimens appeared Is not a structure of eggs or other organisms themselves, but rather a burial structure that occurs after burial of organisms, before mineralization, or during mineralization.The internal structure of Punctatus is composed of horizontal plates that may resemble coral The horizontal plate, soft body growth in the horizontal plate.
