Precambrian. Pre-cambrian (or Precambrian) is a term used to describe the eons before the Cambrian. It lasted from about 4.567 billion years BC to about 542 million years BC. It starts with the beginning of the Earth, about 4.567 billion years BC. When it ends, there were many hard-shelled animals around.

Precambrian (Pre-Cambrian) este un nume informal pentru intervalul de timp înainte de actuala eră geologică Fanerozoic și este împărțit în mai multe ere pe scala de timp geologică. Acesta se întinde de la formarea Pământului în jur de 4500 milioane de ani până la începutul perioadei Cambrian, când organisme macroscopice au apărut pentru prima dată din abundență cu aproximativ 542 milioane de ani în urmă. Precambrian este numită astfel pentru că precede era

- Until the late 1950s, the Precambrian was not believed to have hosted multicellular organisms. However, with radiometric dating techniques, it has been found that fossils initially found in the Ediacara Hills in Southern Australia date back to the late Precambrian. These fossils are body impressions of organisms shaped like disks, fronds and some w...

Precambrian rabbit. " Precambrian rabbits " or " fossil rabbits in the Precambrian " are reported to have been among responses given by the biologist J. B. S. Haldane when asked what evidence could destroy his confidence in the theory of evolution and the field of study. The answers became popular imagery in debates about evolution and the ...

milhões de anos. O Pré-Cambriano (ou Precâmbrico) é o período de tempo desde a formação da Terra há cerca de 4,6 bilhões de anos (Ga) até ao início do Período Cambriano, há cerca de 541,0 ± 1,0 Ma. Esta idade geológica é antes do atual éon Fanerozoico, e é um superéon dividido em vários éons da escala de tempo geológico.
- https://en.wikipedia.org/wiki/Fossil
A fossil (from Classical Latin: fossilis, literally 'obtained by digging') is any preserved remains, impression, or trace of any once-living thing from a past geological age.Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.
