Fossil flora from the Aleksandrovskoe locality (Lower Permian, Kungurian; Krasnoufimsk district of the Sverdlovsk Region): Taxonomical composition, taphonomy, and a new lycopsid representative

  • S. V. Naugolnykh


The Aleksandrovskoe locality (Krasnoufimsk district of the Sverdlovsk Region, Fore-Urals; Lower Permian, Kungurian Stage, Koshelevsk Formation), its taphonomy and taxonomic composition of the fossil flora are discussed. A new lycopsid, Ufadendron ufaensis gen. et sp. nov., with well-developed infrafoliar aerenchyma is described. The new plant is morphologically similar to the group of Early Carboniferous Central Angaran lycopsids (Tomiodendron Radczenko emend. S. Meyen, Lophiodendron Zalessky emend. S. Meyen, Angarophloios S. Meyen). Survival of a relic lycopsid of Central Angaran type with infrafoliar aerenchyma at the periphery of Angaraland up to the mid-Permian is discussed in terms of the “Lazarus taxa” phenomenon.
