MWC 1 is indeed C. magnicornis.  However, it was Madsen and Wells that
penned the paper.  It is not 8.8 meters.  It is only slightly larger than
the holotype (skull 600 mm compared to 550, femur 630 compared to 620).  C.
dentisulcatus (UMNH 5278) is the big one (femur 759).  UUVP 81 is a
mystery.  I am sure it is a bit of C. dentisulcatus (given many field UUVP
numbers.  UUVP does not exist anymore, apparantly)

 And  BYUVP 4951-4952-8907-9142-9144

These are listed as Ceratosaurus sp.  Not enough to pin to a specific
species, I guess.

>C. ingens;

Not Ceratosaurus.  Janensch called it Megalosaurus ingens.  He never pinned
it on Ceratosaurus.  It is too big to be Ceratosaurus.

>C. roechlingi;

Ceratosaurus sp.  Not diagnostic to species level (quadrate and half of an
undiagnostic fibula).

>C. dentisulcatus;

Described in this paper from the very large Ceratosaurus from the
Cleveland-Lloyd Quarry.

>C. willisobrienorum;

Not even mentioned.  Who named this?  Is this another Stephen Pickering
"named in a pamphlet" name?
