Saurornithoides Foot
''Saurornithoides'' ( ) is a genus of troodontidae, troodontid maniraptoran dinosaur, which lived during the Late Cretaceous Period (geology), period. These creatures were Predation, predators, which could run fast on their hind legs and had excellent sight and hearing. The name is derived from the Ancient Greek, Greek stems ''saur~'' (lizard), ''ornith~'' (bird) and ''eides'' (form), referring to its bird-like skull. History of discovery Originally, only one or possibly two individuals of ''Saurornithoides'' were known, closely associated within the same layer of the Djadochta Formation of Mongolia. The fossils were found on 9 July 1923 by a Chinese employee of an American Museum of Natural History expedition, Chih. The material contained a single skull and jaw in association, and vertebrae, a partial pelvis, hindlimb and foot associated nearby. More bones were initially included but later shown to belong to ''Protoceratops''. Henry Fairfield Osborn at first intended to name ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...
