Abstract

Lower Permian conifers of the Cis-Urals are reviewed, their morphological features are considered. The data on the investigated sections of the Artinskian and Kungurian of the Middle Cis-Urals are provided. The diagnosis of the species Walchia bardaeana Zalessky emend. nov is revised and emended. Paleoecological conditions of the Lower Permian conifers of the Cis-Urals and trophic preferences of some Paleozoic insects adapted for feeding on conifer and other gymnosperm seeds in western Angaraland are discussed.

Keywords:

Walchiaceae Walchia conifers Dictyoneurida Paradunbaria insect/plant interaction Permian Urals 

Notes

ACKNOWLEDGMENTS

I am sincerely grateful to A.G. Ponomarenko (Borissiak Paleontological Institute, Russian Academy of Sciences) for valuable discussions on the morphology of Palaeodictyoptera (Dictyoneuridae).

The study was supported by the Russian Government Program for Competitive Growth of Kazan Federal University among World’s Leading Scientific and Education Centers and by the Russian Foundation for Basic Research, project no. 18-04-00322.
