What's the name of the living fossil tree?

The tree species of "living fossils" are: ginkgo, silver fir, Davidia involucrata, Yunnan pine and so on.

1, Ginkgo biloba

Ginkgo tree, also known as ginkgo tree, was called duck foot tree or gongsun tree in ancient times. As early as 270 million years ago, the ancestors of Ginkgo biloba began to appear, and compared with ferns all over the world at that time, it was still a higher plant. By1.700 million years ago, Ginkgo biloba had spread all over the world like dinosaurs that ruled the world at that time. Later, ginkgo mostly became extinct like dinosaurs.

Ginkgo biloba is the only surviving species among gymnosperms of Ginkgo biloba. At present, wild ginkgo can be seen in Tianmu Mountain, Zhejiang Province. Therefore, Ginkgo biloba is known as "living fossil" and "panda" in plants.

2. Metasequoia glyptostroboides

Metasequoia is a deciduous conifer. One of the rare plants with beautiful tree posture, lush foliage and changeable leaf color is a national first-class protected plant.

Metaseuia glyptostroboides is a kind of precious relict plant which experienced the Quaternary glacial disaster. It grows rapidly, reaching 65,438+00 meters in about 65,438+00 years, and it can become a useful material in 20 years. The material is light and soft, with straight texture and fine structure. It is a good material for shipbuilding, construction, bridges, farm tools and furniture, and also a good raw material for paper industry.

3.Davidia involucrata

Davidia involucrata is a deciduous tree. 654.38 million years ago, relict plant, which was left by Cenozoic Tertiary, was extinct in most areas during the Quaternary Glacier Period. Only parts of southern China have survived, and Lucheng agriculture in Luoyang has been successfully propagated and planted on a large scale.

It has become a "living fossil" in today's plant world, known as "China's pigeon tree", also known as "pigeon flower tree" and "water pear". Wild species only grow in Sichuan province in southwest China and Hubei province in central China and its surrounding areas. Davidia involucrata is listed as a national key protected wild plant, which is endemic to China, belongs to relict plant and is also a world-famous ornamental plant.

4. Qian Songqian

Dictyophora dictyophora is a famous ancient relict plant. The earliest fossils were found in the Late Cretaceous strata of East Siberia and West Siberia, as well as the Spitsbergen Islands, Europe, Central Asia, the western United States, northeastern China and Japan from Paleocene to Pliocene.

The trunk of Pinus bungeana is straight, 40m high, DBH 1.5m ... The bark is dark brown and deeply split into scales. Branches rotate and spread, and branchlets are divided into long branches and short branches. The leaves are strip-shaped, flat and soft, and spread spirally on the long branches, and the short branches are clustered with 15-30 pieces, which radiate in all directions and turn golden yellow and round like copper coins in autumn, hence the name.
