| 摘 要： | 松柏类植物是侏罗纪最为繁盛的裸子植物类群之一。通过室内实验和镜下鉴定,对甘肃窑街盆地中侏罗世Pityostrobus sp.的原位花粉进行了研究,并结合现生松科花粉的形态特征,分析对比了其原位花粉与地层中的分散花粉的关系,经对比分析,初步认为Piceites arxanensis是化石Pityostrobus sp.的花粉,而后者是前者的母体植物。化石Pityostrobus sp.的原位花粉特征的研究,对古松柏类化石植物的鉴定和分类具有一定的指导意义;同时,可为进一步研究古松柏类植物在中生代侏罗纪的地理分布和生态特征提供新的线索。

| Abstract: | Cupressaceae is one of the most prosperous genera of gymnosperms in the Jurassic. The in situ pollen of the Middle Jurassic Pityostrobus sp. from the Yaojie Basin in Gansu Province is studied by lab experimental analysis and microscopic identification. Combining with the morphological characteristics of current Pinaceae pollen,this paper analyzes and contrasts the relationship between in situ pollen of Jurassic Pityostrobus sp. and dispersed pollen in the strata. The comparison suggests that Piceites arxane... |
