How the conclusion of Ruben would be affected, if researchers discovered a fossil of a 100-kilogram dinosaur with a nasal cavity greater than 10 square centimeters. Concept introduction: Nasal cavities are large air-filled spaces present above and behind the nose in the middle of the face. These cavities lead to each of the two nostrils. Ruben has used the length of the nasal cavity to determine the process, whether endothermy is present in mammalian ancestors or not.
