摘要
本文研究了6种大别山硅化木,其中南麓有杉木、湖北柏木和海南红豆;北麓有竹柏、油杉和河南松。杉木(Cunninghamia lanceolata Hook.)(图版I-1—3)标本号:HG013 外观特征:硅化木外观灰黄及黄白色。系树木大枝,圆柱状,长31cm,大头直径9cm,小头直径7cm。生长轮明显,轮间介以极窄的深色晚材带,轮宽2—3mm,有假年轮存在。
Six species of fossil woods have been excavated from the Dabie Mountains. Three of them excavated at the southern foot of the Dabie Mountains in Hubei Province have been identified as Cunninghamia lanceolata Hook.,Cupressus(nomen idterminatum)sp. Nov. and Ormosia pinnata Merr. from the Late Tertiary Period, which proved the hot and humid weather during the period. The other three excavated at the northern foot of the Dabie Mountains in Heaan Province have been identified as Podocarpus nagi Pilger, Keteleetia fortunei (Merr.) Carr. and Pinus (nomen idterminatum) sp. Nov. from the Cretaceous Period, which confirmed that the weather at the northern foot of the mountains was colder and drier than that at the southern foot.
