Saltwater Crocodile - Crocodylus porosus
Largest living crocodilian species with a confirmed measurement, and in fact the world's largest living reptile in terms of mass. Adult males can reach sizes of up to 6 or 7 metres (20 to 23 feet), the largest confirmed individual being 20.7 feet (6.3 metres). There is always a lot of interest over the largest ever recorded saltie. In general, males over 5 m (17 feet) in length are extremely rare. Females are smaller, the normal maximum adult size being 2.5 m to 3 m (8 to 10 feet) being the normal maximum adult size. Maximum weight varies, but has been known to exceed 1,000 kg in 18 to 19 foot adults. 5 metre adults are closer to 400 to 500 kg. This is a large-headed species with a heavy set of jaws. A pair of ridges run from the eye orbits along the centre of the snout, becoming more distinct with age. The upper surface of the top jaw becomes very rugose in large adult males.

Ceratosaurus nasicornis
Ceratosaurus meaning "horned lizard", in reference to the horn on its nose (Greek κερας/κερατος, keras/keratos meaning "horn" and σαυρος/sauros meaning "lizard"), was a large predatory theropod dinosaur from the Late Jurassic Period (Kimmeridgian to Tithonian), found in the Morrison Formation of North America, in Tanzania and Portugal. It was characterized by large jaws with blade-like teeth, a large, blade-like horn on the snout and a pair of hornlets over the eyes. The forelimbs were powerfully built but very short. The bones of the sacrum were fused (synsacrum) and the pelvic bones were fused together and to this structure (Sereno 1997) (i.e. similar to modern birds). A row of small osteoderms was present down the middle of the back. Ceratosaurus was a fairly typical theropod, with a large head, short forelimbs, robust hind legs, and a long tail. Uniquely among theropods, Ceratosaurus possessed dermal armor, in the form of small osteoderms running down the middle of its back. The tail of Ceratosaurus comprised about half of the body's total length. It was thin and flexible, with high vertebral spines. The type specimen was an individual about 17.5 feet (5.3 m) long; it is not clear whether this animal was fully grown. David B. Norman (1985) estimated that the maximum length of Ceratosaurus was 20 feet (6 m). A particularly large Ceratosaurus specimen from the Cleveland-Lloyd Quarry (UUVP 81), discovered in the mid-1960s, may have been up to 28.8 feet (8.8 m) long. Marsh (1884) suggested that Ceratosaurus weighed about half as much as Allosaurus. In Predatory Dinosaurs of the World, published in 1988, Gregory S. Paul estimated that the C. nasicornis holotype skeleton came from an animal weighing about 524 kilograms (1,160 lb).

I think their are two sizes for Ceratosaurus one is quite big and the other is smaller, I think the Croc would be able overpower it if it was the smaller estimate, but i'm not sure about the larger estimate.
Croc 65/35
Because of stability (low centre of gravity), bite force

I favour the croc by a slight margin. It's more stable, and one bite would finish the fight, by a death roll to the leg.

I can't find anything reliable on the size of UUVP 81, though that's not to say none exist.

The large C. dentisulcatus specimen UMNH 5278 probably stands the best chance. It has a notable height advantage, and whilst likely not as stong, would be strong compared to other theropods around the same kind of size (I would assume, based on how heavily built it is).

The crocodile would of course be significantly wider than Ceratosaurus.

The Saltie would probably overpower the theropod if it got a grip, whilst Ceratosaurus would probably cause massive flesh wounds with those teeth.
Which ever gets the first good strike in wins imo. I'm leaning ever so slightly towards the croc' though due to strength and size advantage.

am i correct in assuming the crocs bite is much more powerful than ceratosaurus

The ceratosaurus had a slashing bite, rather than a crusher. It would try and rip long, deep wounds in it's prey. A bit like a Komodo dragon in a way, only more so. On land, I favor the dinosaur, it could probably wear the croc down and then kill it. It should be fast enough to evade the crocodile if it could stay just out of reach.

In even shallow water, though, i think the croc wins. The uncertain footing negates the dinosaur's speed advantage and lets the crocodile get a good bite in, and assuming we are dealing with a big salty, then it could probably keep that hold and either pull the dinosaur down or death roll it and rip off a chunk.

So I guess it depends on the envirnment.

@Spinodontosaurus
UUVP 81 doesn't "exists" anymore, it was part of a lot of material cataloged by the UUVP, anyway, when the material was transferred to the UMNH they saw it as belonging to a single individual and gave it the number 5278. The information in the OP is wrong, there isn't any known +8m Ceratosaurus specimen of any species, there's one specimen bigger than UMNH 5278 though but not by much and I don't remember its catalog number or in what book I read about it. There's another specimen as big as UMNH 5278 (~7m), BYUVP 12893, it's not currently assigned to any species, the theropod database says it's a subadult but that's not what Madsen & Welles (2000) says, it says its an adult.

Now, about the fight, If it's against C. nasicornis, I'll favor the croc, its bigger and stronger, the theropod does have a height advantage but I don't think it will make much of a difference, if the croc grabs its leg it's done.

On land ceratosaurus would just wear the crocodile down and bite the back of its head and kill it.

I saw this matchup recently and was wondering, can an aquatic encounter between ceratosaurus and a crocodilian be possible? Various sites mention Ceratosaurus may have been semi-aquatic. The only reasons I've seen as to why scientists believe this is because of its thick powerful tail. I'm not sure thats convincing, so is there any other characteristics that would support a semi-aquatic lifestyle (ie like Spinosaurus)?
An aquatic encounter would be more interesting than the usual land carnivore/crocodilian threads.
