A new docodont from the Totunhe formation (Middle Jurassic) of the Junggar Basin

摘要: During the fieldwork in 2000, a bone—bed was discovered 15 m below the top of the Totunhe Fm. at the Liuhonggou locality some 15 km southwest of the city of Urumqi. Screen washing of samples of the green siltstones and fine sandstones produced a lot of vertebrate remains, mainly isolated bones, scales and teeth of hybodontid sharks, rays, temnospondyles, crocodiles and turtles. Additionally the material yielded a few dinosaur teeth and very few mammalian teeth. Most of the latter belong to docodonts. Besides some milkmolars the diagnostic most valuable teeth are two lower molars and one upper molar. m In. 5.0. sun-lu-fl". afl ‘tn ‘aflnn'fi'flr'_ a
