Asiatosaurus

Asiatosaurus (meaning "Asian lizard") was a genus of herbivorous sauropod dinosaur which lived during the early Cretaceous. Its fossils have been found in China and Mongolia. Its type species is known only from teeth, making it difficult to rely on information until more specimens are found to expand our knowledge. The type species, Asiatosaurus mongoliensis, was described by Osborn, in 1924.[1] It was the first sauropod genus named from East-Asia. In 2020 Molina-Pérez and Larramendi estimated the size of the animal at 31 meters (102 ft) in length, 45 tonnes (49.6 short tons) in weight and with a total height of 17.5 meters (57.4 ft), making it one of the tallest know dinosaurs.[2]
