Abstract

This paper is focused on the characteristics of peltaspermalean pteridosperms from the Lower Permian (Kungurian Stage) of the Mazuevka locality (Kishert District of the Perm Region, Russia). Our research is based on studying the material from the paleobotanical collection stored in the Earth Science Museum at Moscow State University. The peltasperm seed-bearing organ from the Mazuevka locality, which is determined preliminarily in open nomenclature as Peltaspermum sp., is characterized for the first time. The possible entomophily of some representatives of peltaspermalean pteridosperms is suggested.

Mazuevka植物群（低二叠纪，中顺乌拉尔，彼尔姆地区）：分类学组成和古生态的新数据

摘要

本文重点研究了Mazuevka地区（俄罗斯彼尔姆地区的Kishert区）下二叠纪（Kungurian期）的豆科植物蕨类植物的特征。我们的研究基于对存储在莫斯科国立大学地球科学博物馆中的古植物资料的研究。首次对来自Mazuevka地方的圆锥花果种子器官进行了初步鉴定，该器官最初是在开放命名法中确定为Peltaspermum sp.。建议可能的昆虫嗜食性蕨类植物的一些代表。
