Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Muna 2005, masayendisiti akavakazve endocast (replica) yeAcrocanthosaurus cranial cavity vachishandisa computed tomography (CT scanning) kuongorora nzvimbo dziri mukati me holotype braincase (OMNH 10146). Muupenyu, yakawanda yenzvimbo iyi ingadai yakazadzwa nemeninges uye cerebrospinal fluid, mukuwedzera kuuropi pachahwo. Zvisinei, unhu hwomuviri hwouropi uye hwepfungwa dzomusoro hunogona kuzivikanwa kubva pamakumbo emhuka yacho uye kuenzaniswa nemamwe makumbo emhuka dzomumvura dzakaberekerwa makumbo emhuka yacho. Nepo uropi hwakafanana nehwevamwe theropods, hwakafanana zvikuru nehweallosauroids. Inonyanya kufanana nehuropi hweCarcharodontosaurus neGiganotosaurus pane iyo yeAllosaurus kana Sinraptor, ichipa rutsigiro rweiyo fungidziro yekuti Acrocanthosaurus yaive carcharodontosaurid. Uropi hwaive sigmoidal zvishoma (S-yakaumbwa), pasina kuwedzera kwakanyanya kwehuropi hwehuropi, hwakafanana nengwena kupfuura shiri. Izvi zvinoenderana nokuchengetedza kunoita uropi hwezvikwekwe zvisiri zvecoelurosaurian. Acrocanthosaurus yaiva nemakomba makuru uye akaenzana, zvichiratidza kuti yaikwanisa kunhuwidza zvakanaka. Kuvakazve migero yehafu yedenderedzwa yenzeve, iyo inodzora mwero, kunoratidza kuti musoro wakabatwa pakona ye25° pasi porutivi. Izvi zvaiitwa nokuronga endocast kuitira kuti mugero unenge uri parutivi uri semicircular uenderane nepasi, sezvinowanzoitika mhuka painenge yakangwarira.
