Are you a believer to the idea that ceratopsians were omnivorous? If so, why?

I believe that the evidence is convincing, however I don't 100% believe it. I need some more evidence.

I don't think that ceratopsians were true omnivores. Rather I think that they were mainly herbivorous, but may have ate meat or animal protein on rare occasions. But this would not make it an omnivore.

I agree with dino-ken.

Hippos do it. So I don't see why they would on occasions.

Where did you hear this claim? I doubt they were true omnivores. However, going along with what DinosaurMichael and dino-ken said, they might have eaten a little bit of meat on occasion.

absolutely possible, outlandish, but it cannot be ruled out, in the light of evidence and functional anatomy I would even say this sounds pretty realistic.

Maybe the smaller ceratopsians like Leptoceratops were omnivores?

Though the bigger ones such as Triceratops and Torosaurus are too specialized in the plant eater role.

I would call it a possibility, even for the larger ones, but rather rarely.

Possibly opportunistic, so maybe they'd scavenge carcasses, but i doubt they hunted.

I cannot see an animal with the built of a large ceratopsian being an active hunter, it likely wouldn't be fast enough and it would lack the stamina to pursue anything efficiently. That wouldn't be an effective way to sustain itself, why not just keep eating plants and now and then feeding on a carcass?
One would see different adaptions in a hunter.

Now that's just nonsense, ceratopsians did not have predatory adaptations...

I find it likely that both may have been omnivorous, though the larger ones may not have actually killed the animals, for they did not have the adaptations for hunting. They would have scavenged or maybe attacked the occasional unfortunate hadrosaur. Unless the idea that the large ceratopsians were able to run as fast as rhinos was correct, I don't see these ceratopsians killing their own prey (it would be cool if they could though, they would be the Late Cretaceous entelodonts).

It was an idea from a paleontologist who suggested that the ceratopsians occupied an ecological niche similar to a pig, scavenging carcasses occasionally. It wasn't too well accepted, but wasn't 100% discredited.
