Biogeography Of Paravian Dinosaurs
The biogeography of Paravian dinosaurs is the study of the global distribution of Paraves through geological history. Paraves is a clade that includes all of the Theropoda that are more closely related to birds than to Oviraptorosauria, oviraptorosaurs. These include Dromaeosauridae and Troodontidae (historically grouped under Deinonychosauria) and Avialae (including crown group birds, i.e. modern birds). The distribution of paraves is closely related to the evolution of the clade. Understanding the changes in their distributions may shed light on problems like how and why paraves evolve, eventually gaining the ability to fly. Paraves first appeared in the fossil record in early Late Jurassic (163–145 million years ago), then rapidly diversified and dispersed during Cretaceous (145–66 million years ago). They emerged during the Pangaea#Rifting and break-up, breakup of Pangea (since Early-Middle Jurassic), which influenced the biogeographic processes such as speciation, geodispe ...

FMNH Deinonychus
The Field Museum of Natural History (FMNH), also known as The Field Museum, is a natural history museum in Chicago, Illinois, and is one of the largest such museums in the world. The museum is popular for the size and quality of its educational and scientific programs, and its extensive scientific-specimen and artifact collections. The permanent exhibitions, which attract up to two million visitors annually, include fossils, current cultures from around the world, and interactive programming demonstrating today's urgent conservation (ethic), conservation needs. The museum is named in honor of its first major benefactor, Marshall Field, the Department store, department-store magnate. The museum and its collections originated from the 1893 World’s Columbian Exposition, World's Columbian Exposition and the artifacts displayed at the fair.
