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.
