The conifers are an ancient group, with a fossil record extending back about 300 million years to the Paleozoic in the late Carboniferous period; even many of the modern genera are recognizable from fossils 60–120 million years old.
Recent estimates of its age range up to 14,000 years old, and 16,000 years by the latest (2024) estimate. [1] It is located in Utah , United States. This is a list of the oldest-known trees , as reported in reliable sources.
A conifer cone, or in formal botanical usage a strobilus, pl.: strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads.

Conifers in the Swabian alps. In cool temperate regions, conifers often predominate; a widely distributed climax community in the far north of the northern hemisphere is moist taiga or northern coniferous forest (also called boreal forest). [41] [42] Taiga is the world's largest land biome, forming 29% of the world's forest cover. [43]
A pine is any conifer tree or shrub in the genus Pinus (/ ˈ p aɪ n ə s /) [2] of the family Pinaceae. Pinus is the sole genus in the subfamily Pinoideae.. World Flora Online accepts 134 species-rank taxa (119 species and 15 nothospecies) of pines as current, with additional synonyms, [3] and Plants of the World Online 126 species-rank taxa (113 species and 13 nothospecies), [4] making it ...
The typical life expectancy for a giant tortoise is 150 years old. Jonathan has long surpassed that. However, he’s not the oldest known giant tortoise that ever lived.
Giant sequoia. Silvics of North America (1991), [1] a forest inventory compiled and published by the United States Forest Service, includes many conifers. [a] It superseded Silvics of Forest Trees of the United States (1965), which was the first extensive American tree inventory. [3]
