A reassessment of the referral of an isolated skull from the latecretaceous of Uzbekistan to the stem-testudinoid turtlelindholmemys
A fossil turtle skull (ZISP PH 1/17) from the LateCretaceous (upper Turonian, Bissekty Formation) of Dzharakuduk(Uzbekistan, Asia) was used to score the skull characters for the genusLindholmemys (a stem testudinoid) in a recent phylogenetic analysis. Adescription of ZISP PH 1/17 and a new cladistic analysis reveals nocharacters to support its referral to Lindholmemys elegans or to thestem-testudinoid lineage. ZISP PH 1/17 is very similar to North AmericanAdocus, differing mainly in characters of the upper jaw. Therefore, wehypothesize that ZISP PH 1/17 is the skull of either Shachemysancestralis or "Adocus" aksary, adocid shell taxa from Dzharakuduk.Pending additional discoveries and description of turtles fromDzharakuduk, we refer ZISP PH 1/17 to Adocidae, gen. et sp.indet.
