- The nasal cavity of warm-blooded animals houses a complex scroll-like structure made of thin bony plates called the nasal, or respiratory, turbinate.
- Nasal turbinates are found only in warm-blooded creatures. They are responsible for regulating heat and moisture exchange during respiration.
- Because of their gelatinous composition, nasal turbinates rarely survive fossilization.
- The researchers found that, relative to the size of their heads, warm-blooded animals had much larger nasal cavities than cold-blooded animals.
- One of the primary functions of the respiratory turbinate and the bigger nasal cavity of [warm-blooded animals] is to cool their larger brains, not for whole-body metabolism, which was thought to be true.
