Ginnareemimus
Encyclopedia
Kinnareemimus is a genus
of ornithomimosaurian theropod dinosaur
from Thailand
. 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 Valanginian
to Hauterivian
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. Buffetaut et al. suggest the fossils of Kinnareemimus may indicate an Asian origin for advanced ornithomimosaurs.
Kinnareemimus was first described by Eric Buffetaut, Varavudh Suteethorn and Haiyan Tong in 2009
and the type species
is K. khonkaenensis. Kinnareemimus 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". The name "Kinnareemimus" was first mentioned in a 1999 paper by Sasithorn Kamsupha, and (as "Ginnareemimus") in a publication by Ryuichi Kaneko in 2000.
