       Gasosaurus was named in honour of the gasoline company that found the Lower Shaximiao Formation,‭ ‬then known as the Dashanpu fossil quarry.‭ ‬Since its naming Gasosaurus has been the subject of uncertainty‭ ‬regarding its validity and position.‭ ‬There have been claims that it may the same as a slightly older genus called Kaijiangosaurus that is also from the same formation,‭ ‬and like this it has been considered to be a megalosauroid.‭ ‬Gasosaurus has also been considered to be one of the earliest known coelurosaurs,‭ ‬the group of theropods that would go on to produce the tyrannosaurs.‭ ‬Most still credit Gasosaurus as being a member of the Sinraptoridae,‭ ‬the theropod group typified by the genus Sinraptor‭ ‬which is a sub group of the Allosauroidea‭ (‬theropods similar to Allosaurus‭)‬.
