Coal is formed from prehistoric plants buried much closer to the surface, and is unlikely to migrate below 3.2 kilometers (2.0 mi) through geological processes. Most diamonds that have been dated are older than the first land plants , and are therefore older than coal.

The identification of plant fossils in Cambrian strata is an uncertain area in the evolutionary history of plants because of the small and soft-bodied nature of these plants. It is also difficult in a fossil of this age to distinguish among various similar appearing groups with simple branching patterns, and not all of these groups are plants.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
The Private Life of Plants is a BBC nature documentary series written and presented by David Attenborough, first shown in the United Kingdom from 11 January 1995.. A study of the growth, movement, reproduction and survival of plants, it was the second of Attenborough's specialised surveys following his major trilogy that began with Life on Earth.
Biogeography is a synthetic science, related to geography, biology, soil science, geology, climatology, ecology and evolution. Some fundamental concepts in biogeography include: allopatric speciation – the splitting of a species by evolution of geographically isolated populations; evolution – change in genetic composition of a population
The Green Planet is a 2022 British nature documentary series on plants and their relationship with animals, humans and the environment. It was a co-commission from the BBC and PBS and produced by the BBC Studios Natural History Unit in co-production with Open University, CCTV-9, Bilibili, ZDF, France Télévisions and NHK. [1]
Land plants evolved from a group of freshwater green algae, perhaps as early as 850 mya, [3] but algae-like plants might have evolved as early as 1 billion years ago. [2] The closest living relatives of land plants are the charophytes, specifically Charales; if modern Charales are similar to the distant ancestors they share with land plants, this means that the land plants evolved from a ...
