The results showed that: the excretory system of S. tsinlingensis was consisted of kidney, ureter, bladder and cloaca. The kidney included the envelope and essence, essence mainly includes a large number of urinary small tube and a small amount of connective tissue. Among them, the urinary small tube including renal units and collecting duct. The number of renal unit compared with amphibians has been significantly increased. In connective tissue distribution a small amount of elastic fiber, reticular fiber and a lot of collagen fiber. Ureter was formed from many branches of collecting duct, which include mucosa and outer membrane. The mucosa was transition from simple columnar epithelium mucosa to multilayer squamous cells. Mucosal epithelium consists of multiple squamous cells, lamina propria scattered distribution of plasma cells, in the c
