Prompt used to create the image
Scientifically accurate paleoart of Kinnareemimus, a omnivore Ornithomimosauria dinosaur from Barremian times (125.77–121.4 million years ago). Bipedal with the back held roughly horizontal and the tail held straight out behind for balance, never dragging on the ground. NOT standing upright like a kangaroo. An ostrich-like build with long slender legs, a long slender neck and a small head with a toothless beak. Reference: Kinnareemimus is an extinct genus of ornithomimosaurian theropod dinosaur that was discovered in the Early Cretaceous Sao Khua Formation in what is now Thailand. The genus contains only the type species, K. khonkaenensis. The specific epithet is after Khon Kaen Province, which is in northeastern Thailand, where the remains of the animal were discovered. Anatomy: hands held with palms facing each other (not pronated, not palms-down, not dangling); three main weight-bearing toes on each foot; long arms with three slender clawed fingers and wing-like feathers along the forearms; body covered in feathers, tail held straight out. Full body in side view, whole animal visible, standing in an Early Cretaceous river floodplain like the Sao Khua Formation of northeastern Thailand, warm and semi-arid with conifers, cycads and ferns along meandering rivers, no grass and no flowering plants. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.

There is no write-up for this dinosaur yet, but the scientific data below is complete.
Who lived alongside it
Dinosaurs found in the same rock formation as Kinnareemimus (Sao Khua), so they lived in the same region at roughly the same time.
Phuwiangosaurus
Phuwiangvenator
Siamotyrannus
Vayuraptor
Formation data from the Paleobiology Database, counting only each genus's main formations. One formation can span hundreds of thousands to millions of years, so this doesn't mean any two of them ever met.

Holotype: a single partial third metatarsal (an upper-foot bone). Many other bones from the same site, such as vertebrae, hip bones, shin bones and toes, have been referred to it, but they may come from several animals; this diagram shows only the holotype.
Note: this genus, or which bones belong to it, is still debated.
Coloured areas are parts of the skeleton with fossil bones found so far (sometimes just one bone in that area); faint areas have not been found. The outline is a general shape for its group, not this dinosaur's real body.
