Abstract: Postcranial remains of a small theropod dinosaur, including
vertebrae, incomplete pubes, tibiae, an incomplete fibula, metatarsals and
phalanges, from the Early Cretaceous Sao Khua Formation of Phu Wiang, Khon
Kaen Province, NE Thailand, are described as a new taxon of ornithomimosaur,
Kinnareemimus khonkaenensis, gen. et sp. nov. This early 'ostrich dinosaur'
is characterized by a fairly advanced metatarsus, in which metatarsal III,
although still visible proximally between metatarsals II and IV in cranial
view, is markedly 'pinched' more distally and becomes triangular in
cross-section. The condition of its metatarsus shows that Kinnareemimus
khonkaenensis is more derived than the geologically younger primitive
ornithomimosaurs Harpymimus and Garudimimus, but less derived than
Archaeornithomimus. Its occurrence in the Early Cretaceous of Thailand
suggests that advanced ornithomimosaurs may have originated in Asia.

Etymology. From 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.

Also, some other dino-related papers, but I have to run off to teach now.
