摘要: 铁雄果属—Androstrobus在我国首次发现于四川攀枝花上三迭统,在同一层位中同时有保存极好的蕉羽叶一Nilssonia,因此有一定意义,本文特作一简报。

Abstract: This paper reports the first discovery of Androstrobus Schimper from Late Triassic, Baoding coal field in Panzhihua,Schichuan,China. In the same horizon specimens of Nilssonia are well-preserved. In this paper,Androstrobus Schimper fossil plant belongs to a repreductive organ of the cycads,and the male cone fossil is described as Androstobus pagodiformis Hsu et Y. F. Hu. However, Androstrobus had never been discoveried in China before. The leaf fossil from the same horizon specimen is described as Nilssonia sterophylla Hsu et Y. F. Hu. They all belong to Cycadopsida. Their discoveries in China are of an important signifi- cance not only in Chinese palaobiological study,but also in study of the modern cycad flora of Panzhihua regin.
