Sinornithomimus is a genus of ornithomimid dinosaur that lived in the Late Cretaceous Ulansuhai Formation of Alshanzuo Banner, Inner Mongolia, northern China. The first remains were found in 1997 and described six years later in 2003 as the new genus and species Sinornithomimus dongi.
==Discovery and naming== thumb|left|Block containing eight specimens. The first fossil remains of Sinornithomimus were uncovered by Dong Zhiming in the Ulansuhai Formation as part of the Mongol Highland International Dinosaur Project in 1997. They contained at least fourteen skeletons found in close association, nine of which are nearly complete and relatively uncrushed. The find consisted of three sub-adult to adult specimens and eleven juveniles. The unweathered state of the bones, preserved in siltstone interspersed with layers of clay and the absence of evidence for post-mortem movement, argue for a catastrophic event that killed all the individuals present in the find simultaneously and instantaneously.
