Over most of Precambrian time 80 percent of earths history-the only life forms are bacteria ,which appear about 3,500 million years ago. multiple-cells marine animals like spriggina appear at the end of the era
one fact is that the beginning of Precambrian time was essentially the beginning of the earth
It was the Precambrian time period.
Precambrian Era Paleozoic Era Mesozoic Era Cenozoic Era
During the Cambrian period, life began to appear on the planet.
Precambrian eon4567.17-542 million years agoMesozoic era251-65.5million years agoSo precambrian came first...........
During the late Precambrian, about 560 million years ago, the first confirmed macroscopic multicellular organisms appeared. Around 558 million years ago, the first mollusk, Kimberella,appeared in the fossil record.
nope, it happened way after
Because it was created in the precambrian era...The Candadian Shield was formed in the Precambrian Era.The rocks of the Canadian Shield formed during the Precambrian time.

hello there
Jellyfish were not even alive during the Precambrian era because only single-celled organisms lived.
It looked like a sphere
The ediacaran fauna lived during Precambrian time and became extinct then, too. Nobody knows for sure why, but trilobites might have caused their disappearance.
