Sinornithomimus - Desert - 40

Sinornithomimus dongi was found in the highlands of Mongolia in 2003. Late Cretaceous Mongolia wasn't all that unlike the Mongolia of today, and these ostrich-like theropods, which lived in small herds of similarly-aged individuals, would have had to pass through expansive desert areas to reach pockets of water once snowmelt became scarce in the summer. Many of the individuals we have fossils of include some of the most complete dinosaur skeletons, found having evidently been trapped in the mud at a water hole.
