Input: Question: How old was Charles Whitney Gilmore when he described the new species as Ornithomimus asiaticus? Passage 1:One of the main film genres associated with the Weimar Republic cinema is German Expressionism which was inspired by the expressionist movement in art. Expressionist movies relied heavily on symbolism and artistic imagery rather than stark realism to tell their stories. Given the grim mood in post-WWI, it was not surprising that these films focused heavily on crime and horror. The film usually credited with sparking the popularity of expressionism is Robert Wiene's The Cabinet of Dr. Caligari (1920), produced by Erich Pommer. The film tells the story of a demented hypnotist who is using a sleepwalker to perform a series of murders. The film featured a dark and twisted visual style - the set was unrealistic with geometric images painted on the floor and shapes in light and shadow cast on walls, the acting was exaggerated and the costumes bizarre. These stylistic elements became trademarks of this cinematic movement. Other notable works of Expressionism are Friedrich Wilhelm Murnau's Nosferatu (1922), Carl Boese and Paul Wegener's  (1920) and Metropolis (1927) directed by Fritz Lang. The Expressionist movement began to wane during the mid-1920s, but perhaps the fact that its main creators moved to Hollywood, California, allowed this style to remain influential in world cinema for years to come, particularly in American horror films and film noir and in the works of European directors such as Jean Cocteau and Ingmar Bergman.
 Passage 2:In 1923, during the American Museum of Natural History expedition by Roy Chapman Andrews to Inner Mongolia, Peter Kaisen discovered numerous theropod remains in three quarries. These were named and shortly described by Charles Whitney Gilmore in 1933 as a new species of Ornithomimus: Ornithomimus asiaticus. The specific name refers to the Asian provenance. The species was placed in the new genus Archaeornithomimus by Dale Russell in 1972, making Archaeornithomimus asiaticus the type species of the genus. The generic name combines that of Ornithomimus with a Greek ἀρχαῖος (archaios), "ancient", because Russell mistakenly believed that the layers Archaeornithomimus was found in dated to the Cenomanian-Turonian, about 95 million years old, making it one of the oldest ornithomimids known at the time. Gilmore had not assigned a holotype specimen; in 1990 David Smith and Peter Galton in the first comprehensive description of the fossils, choose specimen AMNH 6565, a foot, as the lectotype.
 Passage 3:Norton's first assignment out of West Point was to 12th Infantry Regiment, 4th Infantry Division as a company commander. He then returned to Infantry School in the fall of 1942 to attend the Battalion Commander and Staff Officers Course and the Parachute Course. Following his completion of the course, he reported to the 82nd Airborne Division in North Africa. He was soon promoted to executive officer of the 2d Battalion, 505th Parachute Infantry Regiment. Two months later, he was again promoted, to S-3 (operations officer) of the Regiment. He made his first of four combat jumps as an executive officer, participating in the Invasion of Sicily. After returning to North Africa, he made a second combat jump into Salerno, Italy, blocking German forces who were trying to attack US amphibious forces. His third jump was in support of the Invasion of Normandy on D-Day, 6 June 1944. In July of that year, he assumed command of the 3d Battalion; he was promoted the next month to G3 of the 82d Airborne Division. Norton made his fourth combat jump in September, in the Netherlands to take control of the bridges from the Dutch border to Arnhem as part of Operation Market Garden.
