K. Tsogtbaatar et al. 2019 | Small hadrosauroid that differs from all other non-hadrosaurid hadrosauroids (including Bactrosaurus and Gilmoreosaurus) in the presence of a premaxilla with a ‘double-layer’ oral margin and up to three functional teeth in the dentary tooth row (both convergent in Hadrosauridae). Gobihadros differs from Bactrosaurus johnsoni, Probactrosaurus gobiensis, Eolambia caroljonesi, Claosaurus agilis, Tethyshadros insularis, in the sigmoidal dorsal outline of the ilium and the greater lateral expression of the supracetabular crest. Gobihadros differs from T. insularis, Plesiohadros djaktaensis, and Hadrosauridae in the possession of a spike-like manus digit 1. |
