Proposal to merge Vegaviidae (and Vegaviiformes) with Vegavis (Classification section)

[edit]

Since its initial description, the monophyly of the family "Vegaviidae" has been questioned by subsequent studies including Mayr et al. (2018), with only the fragmentary Polarornis being possibly (yet uncertainly) the only closest taxon. Torres et al. (2025) described a nearly complete skull of V. iaai, specimen AMNH FARB 30899, and classified Vegavis as a member of the Anseriformes within crown group Aves based on their revised phylogenetic analysis, but did not consider Vegaviidae to be a valid family; it was suggested that Polarornis is too poorly preserved to assign it to a definitive taxonomic position. And since many of the content in this article is pretty similar to the Vegavis article, I think we can simply merge Vegaviidae with Vegavis, making it a separate section within the Classification section.

Additionally, the group "Vegaviiformes" was only proposed by Worthy et al. (2017) but ignored by other researchers except for mention from the describers of Conflicto, and PaleoDB lists this order as unused, so I don't think this clade is accepted by most of the other researchers as well, which makes it better to merge both Vegaviidae and Vegaviiformes with Vegavis altogether.
