New data on dinosaurs from the Lower Cretaceous Murtoi Formation of Transbaikalia, Russia

The revised dinosaur assemblage from the Lower Cretaceous Murtoi Formation at Mogoito locality in Transbaikalia, Russia, includes lithostrotian titanosaur Tengrisaurus starkovi known from caudal vertebrae, Sauropoda indet. represented by isolated teeth and metatarsal IV, theropods Ornithomimosauria, Therizinosauria, Dromaeosauridae, Theropoda indet. and ornithopods Jeholosauridae known from isolated teeth and bones. Isolated teeth with sculptured enamel attributed previously to Psittacosaurus sp. are referred here to Jeholosauridae indet. The Mogoito vertebrate assemblage is most similar to that from the Lower Cretaceous locality Khuren Dukh in Mongolia by sharing a turtle Kirgizemys, a choristodere Khurendukhosaurus, and a similar ornithomimosaur.
