|An artist's illustration of Saltillomimus rapidus|
Saltillomimus (meaning "Saltillo mimic") is a highly dubious genus of ornithomimid found in Coahuila, Mexico. Saltillomimus was the first articulated theropod discovered in Mexico and the fourth overall Mexican dinosaur. The type species, Saltillomimus rapidus was described in 2010 by Martha Martínez but many scientists have not accepted the validity of the paper.
The holotype was discovered in 1998 in the Cerro del Pueblo Formation (Difunta Group) by Martha Martínez. The holotype consists of a partial left leg, hip bones and hand bones. A possibly juvenile specimen (consisting of hip and leg bones) was later found at the same site and a string of tail vertebrae once refered to Ornithomimus may have also belonged to Saltillomimus.
