Re: Long-necked stegosaur, head tail mimicry?

We assume, like sauropods,

is being freely used, so maybe, just maybe, this particular stegosaur was
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
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?
