The Late Viséan ammonoid genus Goniatites had a near-global distribution within the tropical seas but was rarely reported from Central Asia. New investigations of the Early Carboniferous sedimentary succession in the Greater Karatau of Kazakhstan revealed a species-poor new assemblage with Goniatites and assists in the biostratigraphic subdivision of the section. The new species Goniatites zhankurganensis and G. abaiensis are described; these species have a morphological position at both ends of the morphological spectrum of the genus.

来自大卡拉托（哈萨克斯坦古大陆）的早期石炭纪铵盐类扁桃体的首次记录。

维森晚期的氨属类Goniatites在热带海洋中具有近乎全球的分布，但中亚很少报道。对哈萨克斯坦大卡拉陶的早期石炭纪沉积演替的新调查显示，新物种与角铁矿的结合较差，并有助于该段的生物地层划分。描述了新种Ghanatites zhankurganensis和G. abaiensis。这些种类在属的形态谱的两端具有形态位置。
