本文介绍了发现于中国东南沿海地区浙江省新昌县中生代地层中的一种化石木新种———新昌南洋杉型木 (AraucarioxylonxinchangenseDuansp .nov .)。这种化石木保存在早白垩世馆头组中、下部的紫红色泥砂岩中 ,分布在新昌县城西部 ,南北绵延 2 5公里、东西宽约 2公里的狭长地区。由于在化石木产区曾发现过多种植物化石 ,因而确定了该区在早白垩世时期处于我国的欧洲 中国植物区内 ,属亚热带 热带气候区 ,种种迹象表明此时气候有些干旱。同区发现的松柏目叶化石 ,其气孔构造与南洋杉科有一定的亲缘关系 ,这一点似乎与化石木之属可以对应。
This article presents AraucarioxylonxinchangenseDuansp .nov., A new fossil wood species found in the Mesozoic strata of Xinchang County, Zhejiang Province, in the southeast coast of China. The fossils are preserved in the middle and lower parts of the Early Cretaceous Guantou Formation in the purple muddy sandstone, distributed in the west of Xinchang County, extending 25 km north to south and 2 km wide in the east and west. Since many fossil plants have been found in the fossil-wood producing areas, it was confirmed that the area was located in the Chinese flora of Europe in China during the Early Cretaceous period and belonged to the subtropical tropical climate zone. There are indications that the climate is arid at this time. The same area found in the cypress leaf fossil, its stomatal structure and Araceae have a certain kinship, which seems to belong to fossil wood and can be.
