Re: Attachment of stegosaurus plates



Cute, but the hat doesn't weigh 50 pounds and there aren't several of
them running down one's back.

Came across this just recently:

Carpenter (1998) notes several times that the staggered rows of plates
would have severely lowered lateral mobility. The body and tail simply
would not have been able to move much without the plates coming apart
from the vertebrae (see diagram of the tail above). So how could
Stegosaurus move at all, let alone swing that tail far enough to the
side to hit anything? Carpenter himself offers a partial solution: The
skin covering the back must have been incredibly thick, and the plates
anchored and buried pretty deep inside fibrous soft tissue. (This
is contrary to some Renaissance-era suggestions by Bakker that the
plates were somehow attached to the muscles, allowing them to be flexed
up and down). The plates were anchored in tough, fibrous skin up to at
least the bottom third of their height (Galton, 2012). As Carpenter
notes, the fact that the plates were anchored in a thick layer of skin
would have allowed the skin and plates to slide relative to the
underlying bone and musculature, which should have increased overall
mobility.

This is pretty close to what I was thinking of. The Carpenter paper
can actually be found on Google books

I wasn't able to find the Galton paper/
