Turanoceratops tardabilis from the Upper Cretaceous (Turonian) Bissekty Formation of Dzharakuduk, Uzbekistan, represents the first definite ceratopsid dinosaur recorded from Asia. Reexamination of the original and study of newly collected material indicate that Turanoceratops has well-developed supraorbital horns and apparently lacks a nasal horn. Turanoceratops is more derived than the more or less coeval Zuniceratops from the Moreno Hill Formation of New Mexico in the presence of double-rooted teeth and of two or three teeth in each vertical dental file.
来自乌兹别克斯坦扎拉库德克上白垩统(土伦阶)比塞克蒂组的迟缓图兰角龙是亚洲有记录的首例确凿的角龙科恐龙。对原始标本的重新研究以及对新收集材料的分析表明,图兰角龙具有发育良好的眶上角,且明显没有鼻角。与来自新墨西哥州莫雷诺山组、时代大致相同的祖尼角龙相比,图兰角龙更为衍化,其特征在于具有双根齿,且每个垂直齿列中有两到三颗牙齿。
