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.
North Africa and southern Levant [47] Last animal in Tunisia was killed in 1902 near Tataouine, in Algeria south of the Chott Ech Chergui in the 1920s, and in Morocco in Missour in 1925. [48] The subspecies was also present in Egypt along the Nile and in the oases of the western desert [3] until the early Middle Ages. [48] Bond's springbok ...
Abstract imagery, widened subsistence strategies, and other "modern" behaviors have been discovered from that period in Africa, especially South, North, and East Africa. The Blombos Cave site in South Africa, for example, is famous for rectangular slabs of ochre engraved with geometric designs. Using multiple dating techniques, the site was ...

African dinosaurs from these time periods include Megapnosaurus, Dracovenator, Melanorosaurus, Massospondylus, Euskelosaurus, Heterodontosaurus, Abrictosaurus, and Lesoth
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
Because of this, the three assemblages are often separated by temporal boundaries rather than environmental ones (timeline at right). As the Ediacaran biota represent an early stage in multicellular life's history, it is unsurprising that not all possible modes of life are occupied. It has been estimated that of 92 potentially possible modes of ...
Of insects, Africa has many thousand different kinds; of these the locust is the proverbial scourge of the continent, and the ravages of the termites are almost incredible. The spread of malaria by means of mosquitoes is common. The tsetse fly, whose bite is fatal to all domestic animals, is common in many districts of South and East Africa. It ...
As such, though rather speculative, by the 2nd millennium BCE, chimpanzees and/or their artistic depictions (e.g., “seated” and “crouched” chimpanzee statuettes developed between 2300 BCE and 1500 BCE) may have been exchanged in a long-distance trade network from West Africa or Central Africa, through East Africa (e.g., Elmenteitan) and ...
