About this record

The holotype skeleton was collected in 1920 by a University of Toronto party and described by William Parks in 1922. The long tubular crest houses looping nasal passages. The specimen is the anatomical basis for every later reconstruction of the animal's voice in this archive.

    Birds are the living descendants of theropod dinosaurs; hadrosaurs are a more distant branch. The link illustrates deep-time kinship rather than direct descent.
