Ah! but no Triceratops bonebeds are known (just unsubstaniated rumors). They occur as solitary skeletons (hence individuals). Other ceratopsians (e.g., Monoclonius) do occur in bonebeds. No sweeping generalities about herding can be made.

I see - thanks for that info. In that case, please substitute Monoclonius for Triceratops in my "hypothesis"!

That is interesting... I wonder why Triceratops would be solitary where others would live in herds. Apart from the relative size of the animals & their frill/horn configurations, what really were the differences among the ceratopsians?

Living in different depositional environments so it only looks like they're solitary? Different behavior? Who knows? The taphonomic process has a way of confounding interpretations. :-) (For a good example of this, check out the literature for the ways the interpretation of the Alberta centrosaurine bonebeds has changed over the past 20 years).
