 coelurosauria  (from greek, meaning "hollow tailed lizards") is the clade containing all theropod dinosaurs more closely related to birds than to carnosaurs. coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; maniraptora includes birds, the only dinosaur group alive today.turner, a.h., makovicky, p.j., and norell, m.a. 2012. a review of dromaeosaurid systematics and paravian phylogeny. bulletin of the american museum of natural history 371: 1â206. most feathered dinosaurs discovered so far have been coelurosaurs; philip j. currie considers it probable that all coelurosaurs were feathered. in the past, coelurosauria was used to refer to all small theropods, although this classification has been abolished. ==anatomy== ===bodyplan=== the studying of anatomical traits in coelurosaurs indicates that the last common ancestor had evolved the ability to eat and digest plant matter, adapting to an omnivorous diet, an ability that could be a major contributor to the clade's success. later groups would hold on to the omnivory, while others specialized in various directions, becoming insectivorous (alvarezsauridae), herbivorous (therizinosauridae) and carnivorous (tyrannosauroidea and dromaeosauridae).[http://www.sciencedaily.com/releases/2010/12/101220163052.htm meat-eating dinosaurs not
