Sinopeltosaurus in Yunnan
Sinopeltosaurus is a dubious genus of extinct scelidosaurid ornithischian dinosaur described by Roman Ulansky. The type and only species is S. minimus of the lower Jurassic Lufeng Formation of Yunnan China, based on an articulated set of ankle bones. In 2016, Peter Malcolm Galton and Kenneth Carpenter identified it as a nomen dubium, and listed it as Ornithischia indet., possible Thyreophora indet. Ulansky variously referred to it as Sinopeltosaurus minimus or Sinopelta minima; Galton and Carpenter, as the first revisers under ICZN, made the former official.
