Research Conducted at Natural History Museum Has Provided New Information about Paleontology

June 3, 2014

By a News Reporter-Staff News Editor at China Weekly News -- Researchers detail new data in Paleontology. According to news reporting out of Guangxi, People's Republic of China, by VerticalNews editors, research stated, "The Yangtze platform of South China was an area of extensive carbonate accumulation during the Late Permian, with abundant benthic fossils and reef buildups. Its northern margin has long been considered to be bordered by deep shelf sediments rich in radiolarians and ammonoids."

Our news journalists obtained a quote from the research from Natural History Museum, "However, recent investigations found a sponge biostrome in deeper shelf settings in the uppermost Permian.The biostrome is about 0.45.m thick with an organic framework formed by autochthonous calcisponges. In contrast to more diverse shallow marine reef communities at this time, the biostrome was almost entirely constructed by the sponge genus Peronidella as the only frame-building organism. This low biodiversity reflects a relatively deep-water environment. Peronidella individuals in the biostrome are apparently larger than the same genus in shallow platform settings, including the diameters of both the sponge bodies and the central tubular spongocoel, as well as the thicknesses of the body walls. This increased size may be related to the low biodiversity and therefore to reduced competition, with sponge individuals having increased space in which to develop."

According to the news editors, the research concluded: "Biostrome development was terminated by volcanic clay deposition."
