About Batyrosaurus
Batyrosaurus is an extinct genus of herbivorous basal hadrosauroid dinosaur known from the Late Cretaceous Bostobe Formation (Santonian to Campanian stage) of central Kazakhstan. It contains a single species, Batyrosaurus rozhdestvenskyi. It is possible that Batyrosaurus represents the same taxon as the doubtful Arstanosaurus akkurganensis as both were found from the same formation.
The type species Batyrosaurus rozhdestvenskyi was in 2012 named and described by Pascal Godefroit, François Escuillié, Yuri Bolotsky and Pascaline Lauters. The generic name is derived from the Batyr, the Kazakh hero warriors. The specific name honours Anatoly Konstantinovich Rozhdestvensky.
The holotype, AEHM 4/1, was found near Akkurgan in a layer of the Bostobinskaya Formation dating from the Santonian-Campanian, about eighty-four millions year old. It consists of a partial skeleton, including a partial skull, the lower jaws, sixty individual teeth, the sterna, the right humerus, the left radius, metacarpals and phalanges. The authors considered Arstanosaurus akkurganensis a nomen dubium and did not refer its material.
