Chinese researchers found that micro-geek sclerites in North Early Cambrian strata

  Nanjing March 21 electrical (Yang Yan-chee) Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences announced the 21, the Institute PhD Pan Bing, who strata in China Early Cambrian north, found a piece of bone fossil micro-geek。 The discovery expands the micro-geek sclerites ancient geographic distribution, the latest research results published in the international journal Paleontology professional JournalofPaleontology。
  It is understood that micro worms sclerites Cambrian second system is a small shell fossils common fossil types, reticular structure, nearly hexagonal mesh, with varied shapes kink, mainly composed of calcium phosphate。 These cancellous bone fossils of the earliest pieces found in England in mid-1975 at Cambrian。 Netlike its shape and relatively small (millimeter) and vividly named micro worms (Microdictyon), but the biological properties of these tiny sclerites still difficult to determine。   Until 1989, China Yunnan Chengjiang Biota discovered the preserved soft-bodied fossils, the researchers did determine cancellous bone piece was originally grown on both sides of the leaf isopods torso, both sides of each trunk has grown 9 pairs of mineralized bone mesh sheet。 Although discrete pieces of bone fossils of micro worms in the Cambrian strata of the more widely distributed global, but for a long time did not find coverage in China's North China platform。
