Latest-known diadectomorph discovered from the Upper Permian of China

Diadectomorpha is a clade of Permo-Carboniferous tetrapods, which was previously only reported from North America and Germany. Although this clade is only moderately diverse, it is central to discussions of Late Palaeozoic vertebrate evolutionary history. It is the first and most diverse example of high-fibre herbivory and is critical to the origin of modern terrestrial communities. Diadectomorpha is also widely accepted as the sister taxon to crown-group Amniota, giving it significant influence on our understanding of amniote origins. —> Read More
