The fossil evidence has indicated that the land ecosystem had already thought after the end-porian mass, which happened about 252 million years ago. The occurrence of extinction known as the most serious in the history of the Earth caused losses of more than 80% of sea species and 70 percent of terrestrial species. Reports suggest that the tropical ripperian ecosystems, found with rivers and wetlands, demonstrated flexibility within a shorter time frame compared to earlier estimates, which was from seven to ten million years.
Frameen and fossil analysis supports findings
according to a Study Published in Elife, Sadement, and Fossil records from Heshngau formation in northern China, has provided evidence of rapidly expected recovery. Researchers examined sediment deposits from lakes and rivers, focusing on plant residues, detection of vertebral fossils, and fossils such as bars and footprints. Dr. Under the leadership of Lee Tian, ​​under the leadership of Associate Researcher at the laboratory of the State of Biogology and Environmental Geology at China University of GeoSines, Wuhan, analyzed the fossil samples spread over the early triassic period, about 252 to 247 million years ago.
Conclusions indicated that at the beginning of the early tricycic, only a few species dominated the landscape, with a much smaller organisms than the life that is pre-existing. Data pointed to a rigid environment with limited biodiversity. Fossils from the Spathian stage, about 249 million years ago, saw an increase in the stems, root marks and buring activity of the plant, which suggests restoration of stable ecosies. The presence of a middle-sized carnivorous vertebra was also recorded, which reflects the formation of multi-level food webs.
Burrowing behavior indication is ecosystem stability
The burrowing activity, which had disappeared to a large extent after the occurrence of extinction, was noted as a major indicator of recovery. The report stated that Buring plays an important role in soil aeration and cycling of nutrients, which facilitates stability of the ecosystem. The revival of this behavior suggests that some species are adapted to environmental stress by demanding underground refuge.
Senior writer Jinnan Tong, major investigator in the major laboratory of the state of biogology and environment geology, Stated For pHys.org that the tropical ripperon zone may have served as ecological refugees, providing stable conditions that allow life to be rapidly reversed than inland areas that dry up. Further research is expected to determine whether there were similar patterns in other areas during the early trichic.
