Yangchuanosaurus Theropod Tooth From Shaximiao Formation, Zigong, Sichuan Province, China?
Pliosaur posted a topic in Fossil ID
Hello, I would like to know if this tooth may possibly be from Yangchuanosaurus species. It is from the Shaximiao Formation, Zigong, Sichuan Province, China Formation is Jurassic age and relatively very little material is known from this formation and particularly in China although seems like Yangchuanosaurus has been described from this location et al. (1978) named Yangchuanosaurus shangyouensis on the basis of CV 00215, a complete skull and skeleton which was collected from the Shangshaximiao Formation, near Yongchuan, Yongchuan District, Sichuan. Tooth measures less than 2 inches and the serrations appears too worn to make an ideal identification, although looking at teeth from skulls of Yangchuanosaurus, they do seem very similar , in shape and size Any help would be appreciated! Thanks!

I recently acquired three tooth fossils from southwestern China initially labeled as a "Plesiosaurus indet." tooth. The specific locality of the tooth fossils is the Lower Shaximiao Formation, Zigong, Sichuan, China. The age of the Lower Shaximiao formation ranges from Early to Middle Jurassic. The only known plesiosaur species from the Shaximiao formation is Bishanopliosaurus zigongensis, a rhomaleosaurus. If these three tooth are indeed identified as a plesiosaur tooth, they probably belong to Bishanopliosaurus sp. Can anyone help me to identify whether these teeth are plesiosaur teeth?
