[Possible functional properties of the labyrinth in Brachiosaurus brancai].
The dimensions of the semicircular canals and the respective ampullae of a complete labyrinth caste of Brachiosaurus Brancai were determined. Using the equation of motion and the dimensions of the semicircular canals the behaviour of the endolymph displacement of the Brachiosaurus labyrinth was calculated. The time constants of the system were found to be between the values 4 sec and 13 sec for T1 and 0.2 sec and 0.5 sec for T2. From these results it was concluded, that the head movements of the animal occurred in a range between 0.02 and 0.1 cps.
