3D digital reconstructions of vocal organs of Antarctic Cretaceous bird Vegavis and Paleogene bird Presbyornis

We provide three-dimensional digital reconstructions, generated from computed tomographic (CT) data, of the vocal organs of the Antarctic Cretaceous bird Vegavis iaai (MACN-PV 19.748) and the North American Paleogene bird Presbyornis sp. (USNM PAL 617185). These were published as online Supplementary Information for the following paper:
