Kinnareemimus

Kinnareemimus is a genus of ornithomimosaurian theropod dinosaur from Thailand.[1][2] It is known only from incomplete remains including vertebrae, partial pubic bones, metatarsals, and an incomplete fibula. The third metatarsal exhibits a distinctive lateral "pinching", known as the "arctometarsalian" condition, variations of which are found in ornithomimosaurs, tyrannosauroids, troodontids, and caenagnathids. Its remains were collected from the Early Cretaceous Sao Khua Formation, dating to the Barremian stage, at Phu Wiang, Khon Kaen Province. Its early occurrence makes it among the earliest (if not the earliest) ornithomimosaur known, depending on the age of the formation.[3] Buffetaut et al. suggest the fossils of Kinnareemimus may indicate an Asian origin for advanced ornithomimosaurs.[3]

The genus was first described by Eric Buffetaut, Varavudh Suteethorn and Haiyan Tong in 2009 and the type and only species is Kinnareemimus khonkaenensis. It was named in honor of Kinnaree, "graceful beings of Thai mythology, with the body of a woman and the legs of a bird, said to inhabit the depths of the legendary Himmapan Forest, by allusion to the bird-like feet of this dinosaur".[3] The name "Kinnareemimus" was first mentioned in a 1999 paper by Sasithorn Kamsupha, and (as "Ginnareemimus") in a publication by Ryuichi Kaneko in 2000.
