It could easily be a tiger of late Cretaceous, Carnotaurus Sastrei.
Evaporation of humidity and the rain that fell on it's back is caused by the body heath.
Big prehistoric forest areas have very unstable weather, and are constantly watered.
I don't like to think of dinosaurs as cold blooded,slowly moving excuses for living beings, instead, In my mind, they are agile, fast, active warmblooded animals.
Such is this Carnotaurus, who stopped briefly to listen around, before moving on trough thick vegetation of this prehistoric jungle.
