Spatiotemporal extension of the Euramerican Psaronius component community to the Late Permian of Cathaysia: In situ coprolites in a P. housuoensis stem from Yunnan Province, southwest China

► An insect, or less likely a myriapod, created a distinctive boring into a stem of Psaronius housuoensis during the Late Permian in Yunnan, southwestern China. ► This discovery extends a distinctive community of Psaronius-related detritivores from the mid Late Carboniferous equatorial wetlands of Euramerica to the more midlatitude, Late Permian habitats of southern Cathaysia. ► This distinctive component community of Psaronius and its trophically interacting organisms constitutes the longest ranging, terrestrial associations in the Paleozoic fossil record.
