U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Passage: Allosaurus wuxuu ahaa allosaurid, xubin ka tirsan qoys weyn oo theropods ah oo ka tirsan kooxda weyn ee Carnosauria. Magaca qoyska Allosauridae waxaa loo sameeyay jilibkan sanadkii 1878 waxaa sameeyay Othniel Charles Marsh, laakiin ereyga si weyn looma isticmaalin ilaa 1970-yadii oo lagu doorbiday Megalosauridae, qoys kale oo theropods waaweyn ah oo ugu dambeyntii noqday taxon qashinka. Tani, oo ay weheliso adeegsiga Antrodemus ee Allosaurus isla muddadaas, waa qodob loo baahan yahay in la xasuusto marka la raadinayo macluumaadka ku saabsan Allosaurus ee daabacaadaha ka horreeya James Madsen's 1976 monograph. Daabacaadaha waaweyn ee adeegsanaya magaca "Megalosauridae" halkii ay ka ahaan lahaayeen "Allosauridae" waxaa ka mid ah Gilmore, 1920, von Huene, 1926, Romer, 1956 iyo 1966, Steel, 1970, iyo Walker, 1964. Ka dib markii la daabacay Madsen's monograph, Allosauridae wuxuu noqday magaca qoyska ee la doorbidayo, laakiin sidoo kale si adag looma qeexin. Shaqooyinka semi-farsamada ayaa loo adeegsaday Allosauridae noocyo kala duwan oo theropods waaweyn ah, sida caadiga ah kuwa ka weyn uguna caansan megalosaurids. Noocyada loo yaqaano theropods-ka ee loo malaynayo inay la xiriiraan Allosaurus waxaa ka mid ahaa Indosaurus, Piatnitzkysaurus, Piveteausaurus, Yangchuanosaurus, Acrocanthosaurus, Chilantaisaurus, Compsosuchus, Stokesosaurus, iyo Szechuanosaurus. Marka la eego aqoonta casriga ah ee kala duwanaanshaha theropod iyo imaatinka daraasadda cladistic ee xiriirka horumarineed, midkoodna theropods-ka hadda looma aqoonsan yahay inuu yahay allosaurid, in kasta oo dhowr, sida Acrocanthosaurus iyo Yangchuanosaurus, ay yihiin xubno ka tirsan qoysaska si dhow ula xiriira.  Su'aal: Qoyskee ayaa loo qaybiyay Theropods sanadkii 1878?
