트라코돈
트라코돈(Trachodon)은 "거친 이빨"(rough tooth)을 의미하며 미국 몬태나주 백악기 후세에 번성하였던 오리너구리류 공룡의 속이다.[1]
트라코돈은 덩치가 큰 이족보행/사족보행 초식동물일 것으로 추정한다.[2]
종
[편집]이 속에 속하는 수많은 종이 있으며 대부분 제1차 세계 대전 이전에 식별되었다. 처음 트라코돈종으로 명명된 것들은 아래와 같다.
모식종: T. mirabilis Leidy, 1856[1]
그 밖의 종:
- T. amurense Riabinin, 1925[3](based on IVP AS collection, a partial skeleton from Upper Cretaceous rocks of the Amur River banks of Heilongjiang in northeast China, amended to T. amurensis and now the type species of Mandschurosaurus)[4]
- T. cantabrigiensis (nomen dubium) Lydekker, 1888[5] (based on BMNH R.496, a dentary tooth from the late Albian-age Lower Cretaceous Cambridge Greensand, Cambridgeshire, England, regarded as a dubious early hadrosaurid)[6][2]
- T. longiceps (nomen dubium) Marsh, 1897[7] (based on YPM 616, a large right dentary with teeth from the late Maastrichtian-age Upper Cretaceous Lance Formation of Wyoming, U.S., later assigned to Anatotitan)[6]
- T. marginatus (nomen dubium) Lambe, 1902[8] (based on NMC 419, disassociated postcranial material; later made the type species of the genus Stephanosaurus marginatus[9] and then referred to Kritosaurus as Kritosaurus marginatus,[10] which is not supported by later reviews.[6][2])
- T. (Pteropelyx) selwyni (nomen dubium) Lambe, 1902[8] (based on NMC 290, a dentary with teeth, from the Dinosaur Park Formation of Alberta; too fragmentary to assign beyond Hadrosauridae)[6][2]
