Arstanosaurus (meaning "Arstan lizard" after the
ceratopsid, or both at the same time (chimeric
).
History
The genus was based on a partial left
Qyzylorda and were named and described as Arstanosaurus akkurganensis in 1982.[1] This is not much material for naming a new genus, and it was largely ignored until the mid-1990s, when the hypothesis that it was really a ceratopsid appeared.[2] Shortly thereafter, a new revision appeared that showed that the characteristics listed as unusual for Arstanosaurus were really based on perspective, and that the maxilla was from an animal like Bactrosaurus, albeit indeterminate (a dubious name). The femur was uninformative.[3] It was regarded as an indeterminate hadrosaurid in the most recent review.[4]
Diagnostic hadrosauroid remains from the same area have in 2012 been named as Batyrosaurus.[5]
A hadrosauroid from the
Gadolosaurus") has at times been identified as Arstanosaurus, but is clearly a distinct genus.[6][7][8]
