Ginkgo biloba

decline

At the end of the Pliocene, Ginkgo fossils disappeared from the fossil record everywhere except in a small area of central China, where the modern species survived.

dietary supplement

Ginkgo leaf extract is commonly used as a dietary supplement, but there is insufficient clinical evidence that it supports human health or is effective against any disease.

leaves

The leaves are unique among seed plants, being fan-shaped with veins radiating out into the leaf blade, sometimes bifurcating (splitting), but never anastomosing to form a network.

living fossil

Ginkgo biloba is a living fossil, with fossils recognisably related to modern ginkgo from the early Permian (Cisuralian), with likely oldest record being that of Trichopitys from the earliest Permian (Asselian) of France, over 290 million years old.

Wikipedia

Ginkgo biloba (Wikipedia) Ginkgo biloba, commonly known as ginkgo or gingko (/ˈɡɪŋkoʊ, ˈɡɪŋkɡoʊ/ GINK-oh, -⁠goh), also known as the maidenhair tree, is a species of gymnosperm tree native to East Asia. It is the last living species in the order Ginkgoales, which first appeared over 290 million years ago. Fossils very similar to the living species, belonging to the genus Ginkgo, extend back to the Middle Jurassic epoch approximately 170 million years ago. The tree was cultivated early in human history and remains commonly planted.
