Abstract
Staminate inflorescences from Cenomanian-Turonian deposits of the Sarbay locality of western Kazakhstan are described as Krassilovianthus gen. nov. The new genus is characterized by the unique structure of the flower, which is unknown in similar platanoid heads. Flowers of Krassilovianthus gen. nov. possess a perianth that is considerably longer than its two stamens. The stamens are bisporangiate and dithecate, with small tricolporate pollen grains. Platanoid reproductive organs and leaves found at the Sarbay locality are considered.
