[dinosaur] Anyone else notice Tribelesodontidae has priority over Tanystropheidae?



The title says it all.  An interesting part of the recent Tanystropheus "hydroides" (yup, another online name without an lsid or Zoobank mention, but it will be valid in October...) description is that the authors write- "

Gervais (1858) has widely been cited as first mentioning the family-group Tanystropheidae. However, this text contains no reference to either Tanystropheidae or Tanystropheus [S6]. Tanystropheus remains are referred to as “Les Tanystrophes” in Gervais (1859), but this does not constitute a valid family-group name [S7]. Instead, Camp (1945) first published the family-group name Tanystrophaeidae, based on Tanystrophaeus (introduced by Cope, 1887 [S8]), which is an incorrect spelling of Tanystropheus von Meyer, 1852 [S3]. Therefore, the corrected name should be Tanystropheidae Camp, 1945 following article 35.4.1 of the ICZN"
If that's the case, then Tribelesodontidae Nopcsa, 1922 has clear priority over Tanystropheidae Camp, 1945.  If you recall, Tribelesodon longobardicus was the name given to the partial skeleton whose long cervicals were confused with long pterosaurian wing phalanges, until Peyer found better skeletons that showed Tanystropheus vertebrae were cervicals, so transferred longobardicus to the genus.  It's a near exact parallel of when Oviraptoroidea (Barsbold, 1976) had to be replaced with Caenagnathoidea (Sternberg, 1940), even though Caenagnathus was seen as a junior synonym at the time.

While I'm here, Funston's (2020) otherwise excellent caenagnathid review has the related taxonomic blunder of claiming if Macrophalangia Sternberg, 1932 is synonymous with and thus has priority over Caenagnathus Sternberg, 1940, "the family would have to be renamed ‘Chirostenotidae’, as Chirostenotes pergracilis is the oldest valid genus in the family."  That's not at all how that works, and even if it did surely you would go back to Elmisauridae first before making up 'Chirostenotidae'!  I don't know how some things get through peer review...
