I don't even think we need to or should respect this enough to bring it up to the ICZN. Retraction is just a word that only has power if people let it have power. There's no Retraction Law of Scientists that we're bound to obey, nor do the editorial policies of Springer Nature have any claim over the ICZN or paleontologists. It'd be the same if Henry Gee declared Tyrannosaurus rex to be officially Expunged. No one has to say "but the ICZN has never addressed what happens if an author Expunges a valid taxon, we better ask them or wait for them to decide." Because it's just another word, regardless of whether a corporation is declaring it so or not. I say we treat this page of text called a retraction as irrelevant to science, taxonomy and nomenclature and only notable for what it implies sociologically about Lida Xing, Springer Nature, etc..

Various items:1) Apparently anotherÂteam is describing the more complete specimen. So that will be fun...2) This is the sort of thing the ICZN committees are set up for. Let the authors (either Xing's team or the other) screw this up, get a petition submitted to the Bulletin, and get a ruling on it. Sort of like a Supreme Court case.
And yes: if they ruled in favor of the retraction, it would be bad.

Subject: Re: [dinosaur] RETRACTION: Oculudentavis, new smallest known Mesozoic bird in amber from Cretaceous of MyanmarÂThe ICZN doesn't say anything aboutÂthem because retractions are fairly new. Which is why there is likely to be a ruling, or at least a discussion, about it.
Basically, it is wise to avoid this taxon like the Plague until it is resolved...

But Nature doesn't decide what counts as published under the ICZN. The original work still fulfills Article 8 and the ICZN says nothing about retractions so it cannot be influenced by them. It's the same as if a dictator decreed some work never existed, even with legal and governmental powers behind them, the status would remain unchanged under the ICZN.

No. It isn't published. That's the distinction between "retraction" and otherÂforms of re-examination. The paper doesn't exist anymore. There is just a gap in the paper version... Or at least that is what we are supposed to consider it. The paper never existed; it was just a delusion.
Retractions are weird...
So yes, with a retraction, technically speaking we ARE supposed to pretend it never existed.
Blargh.

Note the distinction between a Correction (or a Corrigendum) and a Retraction:

"When an important error has been made in a published piece of work, yet the central claim or result still stands, the publication of a Corrigendum is the most sensible way forward; others are thereby alerted to any inaccuracies in the paper, which may have an impact on their own research. If, on the other hand, the errors that have been made undermine the principal message of the paper, then a retraction is in order -- the paper may still contain valid scientific information, but the original publication has now lost its raison d'Ãtre."
In this case, the identification of the fossil as representing an unusual bird is the primary error, and so goes to the main message of the paper. Obviously, a redescription based on an additional and more informative specimen would merit a completely new description and phylo analysis (but not a new name). In this case, assuming the new specimen is also one found in Burmese amber, a change in editorial policies by some journals about research on Burmese amber could complicate the publication situation.

We, the authors, are retracting this Article to prevent inaccurate information from remaining in the literature. Although the description of Oculudentavis khaungraae remains accurate, a new unpublished specimen casts doubts upon our hypothesis regarding the phylogenetic position of HPG-15-3.

Skeletal inclusions in approximately 99-million-year-old amber from northern Myanmar provide unprecedented insights into the soft tissue and skeletal anatomy of minute fauna, which are not typically preserved in other depositional environments. Among a diversity of vertebrates, seven specimens that preserve the skeletal remains of enantiornithine birds have previously been described, all of which (including at least one seemingly mature specimen) are smaller than specimens recovered from lithic materials. Here we describe an exceptionally well-preserved and diminutive bird-like skull that documents a new species, which we name Oculudentavis khaungraae gen. et sp. nov. The find appears to represent the smallest known dinosaur of the Mesozoic era, rivalling the bee hummingbird (Mellisuga helenae)--the smallest living bird--in size. The O. khaungraae specimen preserves features that hint at miniaturization constraints, including a unique pattern of cranial fusion and an autapomorphic ocular morphology that resembles the eyes of lizards. The conically arranged scleral ossicles define a small pupil, indicative of diurnal activity. Miniaturization most commonly arises in isolated environments, and the diminutive size of Oculudentavis is therefore consistent with previous suggestions that this amber formed on an island within the Trans-Tethyan arc10. The size and morphology of this species suggest a previously unknown bauplan, and a previously undetected ecology. This discovery highlights the potential of amber deposits to reveal the lowest limits of vertebrate body size.
