Gigantosaurusとは 意味・読み方・使い方

Gigantosaurus (meaning "giant lizard") is a poorly known sauropod dinosaur genus from England. The type species, Gigantosaurus megalonyx, was named and described by Harry Govier Seeley in 1869. Its type, BMNH 32498-99, consists of several separately discovered sauropod bones found near Stretham, among which two casts of the "large claw" the specific name, derived from Greek megalos and onyx, refers to. Other remains included a cervical vertebra, two caudal vertebrae, the distal end of a tibia, a fibula and a osteoderm. It was synonymised to Ornithopsis humerocristatus by Richard Lydekker in 1888 and to Pelorosaurus by Friedrich von Huene in 1909. Today it is considered a nomen dubium.
