What was the Purpose of the Bony Plates on Triceratops?
The bony plates on Triceratops, known as the frill, served multiple purposes:
Defense: The frill protected the vulnerable neck and head of the Triceratops from predators. Its bony structure could withstand powerful blows from other dinosaurs.
Display: The frill was an important display feature used for communication and courtship. Its size and shape could convey information about age, dominance, and readiness to mate.
Thermoregulation: The large surface area of the frill allowed for efficient heat exchange. The blood vessels near the surface of the frill could dissipate excess body heat or absorb heat from the environment.
Attachment for Muscles: The frill provided an attachment point for multiple muscles, including those used for neck support and jaw movement.
Camouflage: The frill's irregular shape and shadow patterns may have provided some camouflage against predators.
