Cryolophosaurus ellioti
Cryolophosaurus (play /ˌkraɪ.ɵˌlɒfɵˈsɔrəs/ or /kraɪˌɒlɵfəˈsɔrəs/; meaning "cold crest lizard") was a large theropod dinosaur, with a crest on its head that looked like a Spanish comb. Cryolophosaurus was excavated from Antarctica's Early Jurassic (Pliensbachian stage) Hanson Formation (former the upper Falla Formation) by paleontologist Dr. William Hammer in 1991. It is the first carnivorous dinosaur to be discovered in Antarctica and the first dinosaur of any kind from the continent to be officially named (other than birds). Dating from the Early Jurassic Period, it was originally described as the earliest known tetanuran, though subsequent studies have found that it is probably a dilophosaurid. The holotype and only known individual of Cryolophosaurus is estimated as 6.5 metres (21 ft) long and weighing 465 kilograms (1,030 lb); this individual may represent a sub-adult and thus not fully grown, however. A high, narrow skull was discovered, 65 centimeters (25 inches) long. The peculiar nasal crest runs just over the eyes, where it rises up perpendicular to the skull and fans out. It is furrowed, giving it a comb-like appearance. It is an extension of the skull bones, near the tear ducts, fused on either side to horns which rise from the eye sockets (orbital horns).

Eustreptospondylus oxoniensis
Eustreptospondylus ("well-curved vertebra", in reference to the arrangement of the spine in the original fossil) is a genus of megalosaurid dinosaur, from the Callovian stage of the Middle Jurassic period (165 to 161 million years ago) in southern England, at a time when Europe was a series of scattered islands (due to tectonic movement at the time which raised the sea-bed and flooded the lowland). The only known specimen of Eustreptospondylus may not be fully grown, and was about 4.63 metres (15.2 ft) long. It was carnivorous, bipedal and had a stiffened tail. It was a typical theropod, with powerful hind limbs, erect posture and small forelimbs.

How about Eustreptospondylus vs Cryolophosaurus then?

The Cryolophosaurus may have a slight mass advantage and is probably more agile, but the Eustreptospondylus is more robust and has a stronger bite(dilophosaurids don't have slicing dentitions)

Dilophosaurids aren't really very formidable compared to many other theropods...

Cryolophosaurus after an epic battle. Unlike most members here, I don't deny coelophysids. Eustreptospondylus was a scavanger.

Unlike most members here, you overrate Coelophysids.

i'd give this to C. ellioti

i think it's too much to handle for the ~4.3 meter megalosaur, especially when the mass estimates for Eustreptospondylus center at ~220kg

Considering claims of the subadult nature of both specimens are apparently legit, I’ll have to give this to cryolophosaurus on account of being larger. However, I think 220kg is an underestimate. Benson (2010) estimated Piatnizkysaurus and Magnosaurus, which he stated were similar in size to the known Eustreptospondylus material, at over 500kg, and that based on limb-shaft diameter, which tends to produce underestimates.

Cryolophosaurus wasn't a coelophysid. If it was I would give the edge to Eustreptospondylus, but the only charcteristic Cryo shares with the coelophysids is its pelvis. The rest of the skeleton was described as more like an abelisaur or ceratosaur. "where as the skull has many advanced features, leading the genus to be considered a tetanuran, an abelisaurid, a ceratosaur and even an allosaurid." So basically the thing that mattered most in the fight was more akin to ceratosaurs and allosaurs. I give the edge to Cryo 70/30.

Cryolophosaurus wins, due to size advantage.

eustreptospondylus Vs fukuiraptor Would be a good match.

Have you seen this?

I'm rooting for Cryolophosaurus due to a size advantage, since the not-fully-grown subadult specimen is larger than Eustreptospondylus' specimen which is not fully grown as well.

See the thing is that these so called sub-adult specimens always spark sensationalism with their potential maximum size,I mean for the last fifteen years it's been happening to Spinosaurus.So imo it's logical to be conservative with these lengths.

Mistmatch. Adult Eustreptospondylus is 8-10 m long.

Agreed, there really would be no contest and more of a predator-prey type relation.
