Barsbold, as in Barsbold Rinchen, the famous Mongolian dinosaur worker and
inspiration for the name "Barsboldia" (a Mongolia hadrosaur).

There is always the possibility of snails in alkaline lakes...

Also, seeing how lightly built there skulls are, I don't know if
oviraptorids could withstand repeated crushing of medium-shelled molluscs.

My preference is to reserve "thagomizer" for the tail weapons of
stegosaurians (the lateroposteriorally directed tail spines), and to use
"tail club" more generally for the bulbous knobs at the ends of the tails of
ankylosaurids and euhelopodids (and other forms).
