There's a cartoon I remember from my childhood called 'Flight of Dragons' which attempts to offer an explanation for their flight/fire. It claims
they ate limestone, which when digested produced gases (Oxygen or hydrogen I think. Assuming HCl as the stomach acid, would the chemistry not be 2HCl
+ 2CaCO2=H2 + 2CaCl + 2CO2, or is limestone CaCO3, I cant remember) which they retained to inflate, so that they could fly despite their cumbersome
body mass. It also posits a gland in the roof of the mouth which produces an electrical spark, which enables them to ignite the gases to breathe fire.
This was used to control landing, as well as in combat.
I believe that the cartoon was based on a book of the same title, and I recall seeing a documentary when I was about 8 (a long time ago) which
discussed similar ideas. I think it was focussed on the same guy, as the protagonist is a scientist who gets drawn into a fantasy world and seems to
be based on the author.
The documentary also suggested that the strength of the acids required for this reaction might have contributed to the destruction of their bones,
preventing the discovery of remains. Kind of weakens the argument, I know, cause if it destroyed their bones, would it not have similarly scuppered
their gizzards, but that is what I remember. Like I say, it was a long time ago, so I can't claim to have it spot on, but I just thought I'd throw
it out there.
