A living fossil is a deprecated term for an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time of origin of the extant clade. Living fossils commonly are of species-poor lineages, but they need not be.
Plant fossils almost always represent disarticulated parts of plants; even small herbaceous plants are rarely preserved whole. The few examples of plant fossils that appear to be the remains of whole plants are in fact incomplete as the internal cellular tissue and fine micromorphological detail is normally lost during fossilization.
The International Fossil Plant Names Index (acronym IFPNI) is an online database of paleobotany.The site was launched in May 2014 to list the scientific names of fossil plants, algae, fungi, allied prokaryotic forms (formerly treated as algae and Cyanophyceae in particular), algal-related protists and microfossils published using binomial nomenclature.
Equisetum (/ ˌ ɛ k w ɪ ˈ s iː t əm /; horsetail) is the only living genus in Equisetaceae, a family of vascular plants that reproduce by spores rather than seeds. [2]Equisetum is a "living fossil", the only living genus of the entire subclass Equisetidae, which for over 100 million years was much more diverse and dominated the understorey of late Paleozoic forests.

The structures are considered to be one of the oldest ecosystems on Earth, according to NASA, representing the earliest fossil evidence for life on our planet from at least 3½ billion years ago.
Fossil seed capsules of the genus Euphorbia, found in London Clay. A list of prehistoric and extant species whose fossils have been found in the London Clay, which underlies large areas of southeast England. Plant fossils, especially seeds and fruits, are found in abundance and have been collected from the London Clay for almost 300 years. [1]
Ginkgo biloba is a living fossil, with fossils recognisably related to modern ginkgo from the early Permian , with likely oldest record being that of Trichopitys from the earliest Permian of France, over 290 million years old. [46]
