Re: Long-necked stegosaur, head tail mimicry?

We assume, like sauropods,

doing just that. Not moving very much but being able to cover a lot more
ground whilst eating, moving the long neck in an arc, maximising the
energy
intake without moving very much. Just a thought.

But is it even the case that holding the neck far out and moving it around costs less energy than walking a step?

There are millions of four legged animals on the planet today that graze, don't have long necks, and take steps to cover ground. So I tend to doubt why they'd adopt that sort of feeding strategy.


Now, a sauropod is usually bigger, and may well make sense to do things that way. Correlation with size and long necks?
