In recent years, many studies on microbially induced sedimentary structures (MISS) and related biogeological processes have been carried out, and become an important way to understand the evolution of early life and interactions between organisms and environments. However, most reports have focussed on the Mesoproterozoic—Neoproterozoic marine sediments, only a few Phanerozoic and terrestrial MISS have been researched. The MISS presented in this paper, mainly consist of mat growth features and mat destruction features, are well preserved in terrestrial clastic rocks around the P—T boundary in Yiyang area, Henan Province. MISS nearby the P—T boundary in this area might indicate that unusual sedimentary rock records of unique aquatic chemical environment and degradation ecosystem after the late Permian biological extinction events. They can be named as “terrestrial anachronistic facies”. MISS's exploration in P—T boundary in the terrestrial environment is meaningful to understand the ecosystem after the mass extinction, and useful for stratigraphical classification and correlation.
