Re: [Re: Platyhystrix and dinosaur humps/sails]
Figured I'd add my two cents as well.
I noticed that sail comparisons on the list ranged from many extinct
creatures, to a couple extant mammals.
Since nobody mentioned any extant reptiles that have sails, I figured I might
At least two chameleon species (_C.quadricornis_ & _C.montium_) have bone
braced sails, like those on spinosauroids and other prehistoric animals.
In these species the sails are used for attracting females (who as you can
imagine, are sail-less) and possibly ward off other males.
Another group of lizards also have sail backs. Basilisks (in particular
_B.plumifrons_) and again it is used in mate attraction.
I'm unsure whether or not basilisks have a bony brace to their sails, but from
their external appearance, it does seem that way.
None of the lizards seem to use their sails for thermoregulating, though I
imagine that it would play a part, even if secondary.
Judging from this, I wonder just how important those sails were when it came
to regulating body temperature.
Meter's out, I'm done.
