Re: Long-necked stegosaur, head tail mimicry?



Could the long neck of this stegosaur be useful in confusing predators, so that 
they become unsure which is the end to be avoided (ie. the tail with the 
thagomizer). I think some arthropods use this kind of head or tail mimicry. It 
would be far more confusing if they lived in large herds.

Yes.

Apparently.

No idea, I haven't read most of the relevant papers.

Yes.
