In one of Larson's `Far Side' cartoons, a lecturer is giving a
military-style pre-briefing session to a group of cave men,
using a huge picture of a stegosaur.  Pointing with his rod to the
spiked tail, he says, "And this end we call the Thag-o-mizer,
in honor of the late Thag Simmons".

I think this classic cartoon has been picked up by (some subset of) the
paleontology community, and the word thagomizer semi-officially refers
to the grouping of 4 or 6 spikes at the tail of a Stegosaurus.
does anyone know if `thagomizer' been used as a specific term in a
refereed paper?  Conference lecture?
