Kryptohadros

Kryptohadros () is an extinct genus of hadrosauroid ornithopod dinosaur known from the Late Cretaceous (Maastrichtian age) Densuș-Ciula Formation of Romania. The genus contains a single species, Kryptohadros kallaiae, known from a partial skull and skeleton. Phylogenetic analyses revealed Kryptohadros is closely related to the coeval Transylvanian Telmatosaurus and the Italian Tethyshadros, together forming a group of southeastearn European-endemic taxa, called the Telmatosauridae. Kryptohadros is the second named non-hadrosaurid hadrosauroid from the Hațeg Basin, following Telmatosaurus, which was named by Franz Nopcsa in 1903.

==Discovery and naming== The Kryptohadros holotype specimen, LPB [FGGUB] R.2882, was discovered between 2022 and 2024 in the Fântânele-3 site of the uppermost Densuș-Ciula Formation in the westernmost part of Hunedoara County, Romania. The associated fossil material preserves a partial skull, dorsal rib fragments, caudals, neural spine fragment, chevrons, and a partial hindlimb. The fused vertebral column elements and the size of the known material indicate that the fossil belongs to an individual that at least reached a subadult stage.
