If they were used for
controlling body temperature, they should be very rich in arteries and veins,
and, honestly, I didn't have read any article exposing this situation on
_Amargasaurus cazaui_, but yet, is a possibility.

This is what I think:
1. Sexual Dimorphism. (Male having a bigger and brighter sail, and female
having a smaller less colorful sail).
2. Male having the brightest colors on the sail gets the females.
3. Temperature Control.
4. Way of identifying there group by different color patterns.
5. Or maybe to guide it in the water. When crossing rivers, that are quite
rough. (Nah that would create more problems, never mind that one).
