Triceratops had large nasal passages likely for two main reasons: to enhance their sense of smell and to help regulate body temperature. The increased airflow through these passages would have allowed for better olfactory capabilities, aiding in foraging and predator detection. Additionally, the large nasal passages may have facilitated the cooling of blood as it passed through, helping the dinosaur maintain a stable internal temperature.
