If I'm right and from what I have in my computer, Megalosaurus ingens is a
synonym of ?Ceratosaurus ingens which is a [nomen dubium] infact in the list
of the African Dinosaurs compiled by George Olshevsky is listed as follows:

Ceratosaurus Marsh, 1884
?C. ingens (Janensch, 1920) Paul, 1988 [nomen dubium]
      = Megalosaurus ingens Janensch, 1920 [nomen dubium]
      = Labrosaurus stechowi Janensch, 1920 [nomen dubium]
      = Antrodemus stechowi (Janensch, 1920) Steel, 1970 [nomen dubium]
      = Antrodemus steschowi Chabli, 1986
      = Labrosaurus steschowi Chabli, 1986

And Paul in his "PDW" mentioned that there was the possibility of the
presence of a titanic species of Ceratosaurus in the Tendaguru beds.
