Rhadinosaurus is a genus of nodosaurid ankylosaur described in 1881 by Harry Govier Seeley, from remains found in Austria. The name means "slender lizard". It lived about 80 million years ago (during the Late Cretaceous period). The type species is R. alcinus.
Fossils
The type specimen consists of two humeri, two fibulae, and two dorsal vertebrae. The fibulae were originally identified as femora in the original description, but were eventually re-identified in a 2001 review of ankylosaur specimens from the Grünbach Formation.[1]
Taxonomy
Rhadinosaurus was initially classified as a dinosaur of uncertain position, but Franz Baron Nopcsa synonymized it with Struthiosaurus[2][3]. It was also considered an ornithosuchid as well as possible synonym of Doratodon, but current opinion classifies it as a probable synonym of Struthiosaurus.[4][5][1]
