These are the oldest known trees of the world's first forests. Prototaxites was the fruiting body of an enormous fungus that stood more than 8 meters tall. By the end of the Devonian, the first seed-forming plants had appeared. This rapid appearance of so many plant groups and growth forms has been called the "Devonian Explosion".
The oldest living spider, named Number 16 by researchers, was a 43-year-old female Gaius villosus armored trapdoor spider, at the North Bungulla Reserve, Tammin, Western Australia. [ 137 ] Debby , the polar bear, an inhabitant of the Assiniboine Park Zoo in Winnipeg, Canada , was the oldest polar bear and third-oldest bear species on record ...
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.
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 ...
Pando, a colony of quaking aspen, is one of the oldest-known clonal trees. 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. Definitions of what constitutes an individual ...
A Palmer oak in Jurupa Valley is estimated to be 13,000 to 18,000 years old. The plant, which looks like a sprawling, dark green shrub, is now at the center of a development battle.
As for life on land, in 2019 scientists reported the discovery of a fossilized fungus, named Ourasphaira giraldae, in the Canadian Arctic, that may have grown on land a billion years ago, well before plants are thought to have been living on land. [100] [101] [102] The earliest life on land may have been bacteria 3.22 billion years ago. [103]
Scientists discovered the oldest known DNA and used it to reveal what life was like 2 million years ago in the northern tip of Greenland. ... the area was filled with an unusual array of plant and ...
