The authors revise anatomical scorings and referral assumptions and recover Cryptovaranoides as an archosauromorph or indeterminate neodiapsid in tested matrices.
Claim ledger
topology · contestedCryptovaranoides holotype NHMUK PV R36822 and disputed referred bones currently support incompatible published placements because element identity, referral and character scoring differ; this package does not treat the taxon as a secure crown-squamate first appearance.
