Asiatosaurus


Asiatosaurus is an extinct genus of herbivorous sauropod dinosaur which lived during the Early Cretaceous in Mongolia and China. The type species is known only from teeth, making it difficult to rely on information until more specimens are found to expand our knowledge, and another species is known, also based on scant remains; both are now classified as nomina dubia. This genus was classified within Brachiosauridae by Hou et al. in 1975, and considered a euhelopodid by Poropat et al. in 2022.
