Data from: Fossil evidence of the avian vocal organ from the Mesozoic
From complex songs to simple honks, birds produce sounds using a unique vocal organ called the syrinx1, 2. Located close to the heart at the tracheobronchial junction, vocal folds or membranes attached to modified mineralized rings vibrate to produce sound1, 2, 3, 4, 5, 6, 7. Syringeal components we...

From complex songs to simple honks, birds produce sounds using a unique vocal organ called the syrinx1, 2. Located close to the heart at the tracheobronchial junction, vocal folds or membranes attached to modified mineralized rings vibrate to produce sound1, 2, 3, 4, 5, 6, 7. Syringeal components were not thought to commonly enter the fossil record6, and the few reported fossilized parts of the syrinx are geologically young8, 9, 10, 11 (from the Pleistocene and Holocene (approximately 2.5 million years ago to the present)). The only known older syrinx is an Eocene specimen that was not described or illustrated12.
