microdontosaurusとは 意味・読み方・使い方

"Microdontosaurus" (meaning "tiny-toothed lizard") is the name given to an as yet undescribed genus of sauropod dinosaur from China. It was named from fossils from the Middle Jurassic-age Dapuka Group of Xinjiang, and assigned to the Homalosaurpoidea, an outdated classification of diplodocids and titanosaurs. The intended type species is "M. dayensis." Due to its obscurity, at least two other identifications of "Microdontosaurus" can be found on the Internet. One identification, as given by The Dinosaur Encyclopaedia, claims the name refers to a sauropod from the Late Cretaceous. The other identification, as given in this Dinosaur Mailing List post, is that the name is for a melanorosaurid prosauropod. As with other informal names created by Zhao in 1985 or 1983, it has not been used since then, and may have been redescribed under another name.
