Occasionally the tail or fore
feet touched the ground as they walked; and when they sat down, they
rested on the end of the pubic bones and on the tail. So much we can
infer from the footprint impressions. The general appearance is shown
in the restorations of _Ornitholestes_, _Compsognathus_ and
_Anchisaurus_ by Charles Knight.

[Illustration: Fig. 18.--Restoration of _Ornitholestes_, by C.R.
Knight under direction of Professor Osborn. _After Osborn_]
_Ornithomimus._ The skeleton of this animal from the Cretacic of
Alberta was found by the Museum expedition of 1914. It is
exceptionally complete, and has been mounted as a panel, in position
as it lay in the rock, and with considerable parts of the original
sandstone matrix still adherent. The long slender limbs, long neck,
small head and toothless jaws are all singularly bird-like, and afford
a striking contrast to the Tyrannosaurus. At the time of writing, its
adaptation and relationships have not yet been thoroughly
investigated.

skeletons have been secured from the upper Triassic (Keuper) near
Halberstadt in Germany.
