Eotriceratops xerinsularis

upload.wikimedia.org/wikipedia/commons/thumb/e/e7/Eotriceratops_BW.jpg/220px-Eotriceratops_BW.jpg

Order: Ceratopsia
Family: Chasmosauridae
Length: 9-11 meters; holotype was not fully grown, so it would have gotten larger
Mass: >13.82 tonnes based on relatives; holotype was not fully grown, so it would have gotten larger
Diet: Plants; possibly an omnivore
Age and Location: 68 million years ago, Late Cretaceous period, Alberta, Canada
Killing apparatus: Horns, beak
One of the largest of ceratopsians. Thought to be a direct ancestor to Triceratops.

Dreadnoughtus schrani

Order: Sauropoda
Family: Titanosauria
Length: 26 meters; this specimen is not fully grown so the adult would be larger
Mass: 48.4 tonnes; this specimen is not fully grown so the adult would be larger
Diet: Plants
Age and Location: 75 million years ago, Late Cretaceous, Argentina
Killing apparatus: Manual and pedal claws, tail slapping, spike osteoderms (based on relatives)
One of the most complete giant sauropods. Had its weight somewhat overestimated by using limb-bone regressions.

I think Palaeoloxodon Namadicus would be a much more interesting match since Eotriceratops weighed over 13 tons. But an adult probably weighed somewhere between 15-18 tons. But in this battle, the sauropod wins, just too big.

I think this overall depends on the mass of the animals as adults.
Dreadnoughtus most likely wins due to size advantage, but Eotriceratops probably has a chance due to better weapons.

I don’t know about you but I don’t think Eotriceratops was a director ancestor to Triceratops. Eotriceratops only lives around 800,000 years before the first Triceratops appeared. I think Ojoceratops was a better possibility. My theory is Eotriceratops evolved to Ojoceratops then Ojoceratops evolved to both Triceratops. I know it sounds weird that both dinosaurs appeared almost the same time. But the truth is that sometimes ancestors and descendants coexist for a while and go extinct at different times. So my theory is that some of the Ojoceratops population moved up to the northern states and evolved to be slightly bigger or around the same size and adapted tot he new environment. But back to the topic, even though Eotriceratops was large it would stand a chance against Dreadnoughtus. I would actually prefer Paraceratherium, Steppe Mammoth, or Palaeoloxodon Namadicus vs Eotriceratops, think those are more even matches for the ceratopsian.

Dreadnoughtus dominates this fight due to its larger size and having a powerful neck and powerful tail, not even the horns of Eotriceratops can save it from the sauropod.

The sauropod is just too large.
