Резюме

В этой статье мы представляем подробное описание голотипа Adocus (ориг. Shineusemys) planus из позднего мела Монголии. Голотип, первоначально указанный как пластрон, в действительности представлен неполным панцирем с почти целым пластроном и несколькими фрагментами карапакса на внутреннем ядре. Переизучение голотипа A. planus позволяет нам представить новые изображения этого экземпляра, исправить его диагноз и впервые включить его в филогенетический анализ Adocusia (Adocidae + Nanhsiungchelyidae). Филогенетический анализ помещает A. planus в состав клады Adocus в политомии с другими видами этого рода. Этот результат подтверждает высказанное нами ранее предположение о том, что Shineusemys следует рассматривать как младший субъективный синоним Adocus.

Ключевые слова
