Ceratosaurus, not so much.

Many European fossils have also, in the past, been assigned to the Camptosaurus genus as C. prestwichii. Paul (2010) questions the genus of Camptosaurus for these European animals but also recognizes C. aphanoecetes, which is not as popularly known as C. dispar. This is strange because it is believable and logical that C. dispar is the direct ancestor to the younger C. aphanoecetes. Of course, this is also because, while the majority of the skeleton has been found at this time, not as much of the skelton and skull have been recovered as have been found for its ancestor. It's not much of a surprise, regardless of which species you knew before, to find that Camptosaurus is considered a basal Ankylopollexia (an early branch of Iguanodontids) based on its body shape and carriage.
