 Acrocanthosaurus may be known from less complete remains outside of Oklahoma , Texas , and Wyoming . A tooth from southern Arizona has been referred to the genus , and matching tooth marks have been found in sauropod bones from the same area . Several teeth from the Arundel Formation of Maryland have been described as almost identical to those of Acrocanthosaurus and may represent an eastern representative of the genus . Many other teeth and bones from various geologic formations throughout the western United States have also been referred to Acrocanthosaurus , but most of these have been misidentified ; there is , however , some disagreement with this assessment regarding fossils from the Cloverly Formation .
