1　压型化石　植物遗传体在沉积物中被压实而呈扁实状态 ,随着细胞的压扁 ,内部的结构随之消失 ,常常留下一层与植物残骸原形一致的碳质薄膜 ,这种化石类型称为压型化石 ,是最常见的植物化石类型。在压型化石上植物叶片表皮层、气孔等的细胞形态均可完好保存。2　印痕化石　印 1 Molded fossil plant genetic material in the sediment is compacted and was flat, with the cells crushed, the internal structure disappear, often leaving a layer of carbonaceous plant thin film consistent with the original shape of the plant, which The type of fossil, known as compression fossil, is the most common type of plant fossil. In the pressed fossil plant epidermis, stomata and other cell morphology can be well preserved. 2 imprint fossil print
