Triceratops likely used its nose to regulate body heat and moisture, new CT scans show.
A new study reveals Triceratops likely used its large nose to regulate body temperature and moisture, based on CT scans of fossil skulls and comparisons with modern animals.
Researchers found unique nasal structures, including a respiratory turbinate for heat and moisture exchange, and rerouted nerves and blood vessels through the nasal passage due to skull shape.
These adaptations suggest Triceratops managed heat from its massive head, though it was not fully warm-blooded.
The findings offer the first detailed hypothesis on soft-tissue anatomy in horned dinosaurs and fill a major gap in understanding their physiology.
