They were described by Marsh when he created the species _Stegosaurus
stenops_; there are lots of them in the "road kill" specimen on display at
the Smithsonian.

They are small dermal bones that fit together to protect the ventral surface
of the muzzle, throat, and neck. They were found in that position in both the
"road kill" specimen and in the 1992 complete skeleton now at the Denver
Museum of Natural History.

One small step for [a] man, one giant leap for mankind.
