Ginkgo huttonii is an extinct
broad-leaved, deciduous gymnosperm[1] bearing resemblance to the only living member of the Ginkgoaceae, Ginkgo biloba.[2]
Description
compression fossils of its leaves. Similar to other members of the Ginkgoites, the fossil leaves of G. huttonii are simple, four-lobed, and have dense, radially disposed venation.[3][2] G. huttonii fossil seeds are frequently found as well as at least a few fossilized male catkins.[4] G. huttonii wood has yet to be described but it is likely the plant was similar to the extant, G. biloba, with wood akin to that of modern-day conifers.[5]
Distribution
G. huttonii is heavily represented in the
Lower Jurassic through the Cretaceous.[7]
Discovery
G. Huttonii was discovered in the 1800s when excavation began throughout the Yorkshire formation. The fossil was first described by Oswald Heer.
