I can imagine Torvo as the T-rex of the Jurassic. It seems to have the strongest bite, which could be able to crush the bones or armor of large, tough animals like stegosaurs or early ankylosaurs, killing these defensive animals as quickly as possible. Its narrower width also allowed it to maneuver through dense forests or jungles, and sneak up on unsuspecting prey, lunging at the prey in a quick burst of speed and using brute force to lethal effect.
Allo and Sauro seemed to be better adapted to open environments, using their stamina, agility, and possible gangs to take down massive sauropod, tearing through their hide and flesh to slowly kill them through blood loss. What they lacked in jaw power or tooth strength, they made up for in jaw flexibility and teeth sharpness, giving them swift cutting power, perfect for taking down animals too large to overpower with brute force. Cerato was somewhere in the middle. Their jaws seemed proportionally stronger than allos or Sauro, but weaker than Torvo. These predators probably hunted the iguandonts and dryosaurs of the time, as they were not too massive and not too heavily armored, a perfect sized and more easily huntable meal. Ceratos teeth were also very long, equally as robust as they were sharp. I would say they had great piercing power in their jaws, kind of like a big cat.. They could tightly clamp around a prey's neck, back, abdomen or head, stabbing their saber-like teeth deep into the muscles, arteries and guts of prey. They could slit their preys throats or penetrate the skull to damage the brain. They would kill their prey through shock from damaged vital organs.
Think about it. What would the ancestor of Torvosaurus looked like about 10 or so million years earlier (right about the same time Megalosaurus existed)?
Currently Saurophaganax is larger however those calculations are based on very limited remains so this could change as new information is released. But that's normal for paleontology.
What *hard evidence* do we have that Ceratosaurs were “pack hunters,” aside from their “second-tier predator” size? Even the evidence that *Cretaceous dromiosaurs* were “pack hunters” is questionable--the presence of several dromiosaur skeletons in close proximity to one another at a kill-site CAN be interpreted as temporarily cooperative scavenging rather than as “pack behaviour”--so I need to be *convinced* Jurassic Ceratosaurs in the Morrison Formation were pack-hunters, given that they were considerably larger than nearly all Cretaceous dromiosaurs, other than Utahraptor and Dakotaraptor.
