Ceratosaurus vs. Allosaurus

[John Schneiderman <dino@revelation.unomaha.edu>]

Wanted information: feel free to speculate

Ceratosaurus
    hatchling length:         mass:      (kg) 
average adult length:         mass:      (kg)
maximum adult length:         mass:      (kg)

Did the hatchling have the nasal horn or did it develop as the animal grew
to adulthood?
Did both sexes had the nasal horn?

How useful were its hands?

Did Ceratosaurus have a row of scutes running the length of dinosaur?
How much protection could these scutes provide?

Was Ceratosaurus' flattened tail an useful swimming organ?
