About Sinornithomimus:

By all rights, Sinornithomimus should be a better-known dinosaur, at least as popular as other "bird mimics" like Gallimimus and Ornithomimus. This relatively basal (i.e., unevolved) ornithomimid is known from two spectacular fossil discoveries in China, the first consisting of the tangled skeletons of three adults and 11 juveniles (which died en masse in some natural diaster), and the second made up entirely of babies and children. Clearly, Sinornithomimus wandered the plains of Asia in small family groups or packs, though it seems the juveniles were sometimes left to fend for themselves while the adults tended to their eggs or, perhaps, warded off predators.
