Tirohia te wāhanga i raro nei, kātahi ka whakautu i te pātai i muri mai i te reo kotahi me te wāhanga:  Passage: I te tau 2005, i hangaia e nga kaiputaiao he endocast (replica) o te kopu kopu o te Acrocanthosaurus ma te whakamahi i te tomography rorohiko (taatai CT) hei wetewete i nga waahi i roto i te roro holotype (OMNH 10146). I te ora, ko te nuinga o tēnei wāhi i whakakiia ki ngā pūngāwerewere me te wai roro-roto, hei tāpiri ki te roro anō. Heoi anō, ka taea te whakatau i ngā āhuatanga whānui o te roro me ngā uaua kopu mai i te endocast me te whakataurite ki ētahi atu theropods mō nei endocasts kua hanga. Ahakoa he rite te roro ki te maha o nga theropods, he tino rite ki te allosauroids. He rite rawa ki nga roro o Carcharodontosaurus me Giganotosaurus kaua ki era o Allosaurus, o Sinraptor ranei, e tautoko ana i te whakapae ko Acrocanthosaurus he carcharodontosaurid. Ko te roro he paku sigmoidal (S-ahua), kaore he whanui o nga hemispheres roro, he rite ki te crocodile atu i te manu. E ōrite ana tēnei ki te āhua o te pūmautanga o ngā roro theropod kāore i te coelurosaurian. He nui, he porohita hoki nga porohita kakara o te Acrocanthosaurus, e tohu ana i te kakara pai. Ko te hanganga anō o ngā awa haurua o te taringa, e whakahaere ana i te pauna, e whakaatu ana i te upoko i te koki 25° i raro i te pae. I whakatauhia tenei ma te whakatikatika i te endocast kia rite ai te awa haurua o te taha ki te whenua, pera i te wa e noho ana te kararehe i roto i te tuari mataara.  Pātai: He aha te momo wai e kapi ana i te nuinga o te roro o te holotype?
ngā pūngāwerewere me te wai ā-roto
