Rapator
''Rapator'' is a genus of theropod dinosaur from the Griman Creek Formation of New South Wales, Australia, dating to the Albian age of the early Cretaceous period, 105 million years ago.〔 It contains only the type species, ''Rapator ornitholestoides'', which was originally named by Friedrich von Huene in 1932.〔Huene, F. von. (1932). ''Die fossile Reptil-Ordnung Saurischia, ihre Entwicklung und Geschichte''. Monogr. Geol. Pal. 4 (1) pts. 1 and 2, viii + 361 pp.〕
==Description==
The holotype and only known specimen, BMNH R3718, consists of a single left hand bone, discovered around 1905 near Wollaston, on the Lightning Ridge.〔 The fossil has been opalised.〔 The bone has a length of seven centimetres.〔 This manual element shows a prominent dorsomedial process, a feature shared with the much smaller ''Ornitholestes'' which occasioned the specific name.〔 The process with ''Ornitholestes'' is much less distinctive though.〔 On its upper end there is only one cotyle, from which von Huene deduced it must have been a metacarpal.〔 However, several coelurosaurian groups lack a second cotyle on the first phalanx also. If ''Rapator'' had a build like ''Australovenator'', it would have attained a considerable size: a body length of nine metres (30 ft) has been estimated.〔
