Twenty-two endocasts of 12 specimens of Amurosaurus riabinini Bolotsky
et Kurzanov (Lambeosaurinae, Hadrosauridae) have been examined. The
most important neurobiological features of this species and
duck-billed dinosaurs integrally are discussed. It has been
established that the sense of smell played the major role in
afferentation of hadrosaurids. In lambeosaurines, the vomeronasal
sense of smell was probably intensified to search for sexual partners
at a large distance. The hypotheses of sound and visual communications
of duck-billed dinosaurs are not corroborated.
