When did the ediacaran fauna exist?
The Ediacaran fauna existed during the Ediacaran period, approximately 635 to 541 million years ago. This period was just before the Cambrian explosion, which marked the rapid diversification of multicellular life forms.
Were there any trees during the PreCambrian period?
There were no trees in the Precambrian Super-Eon (4576.2 - 542Ma). There were plants in the Precambrian. Simple green algae associated with aquatic environments were thought to evolved around 2.5 billion years ago during the Proterozoic Era. It was not until the Cambrian Period 510 million years ago, the 1st complex land plants evolved. The first trees do not appear in the fossil record until the Late Devonian Period about 385 million years ago.
Precambrian Time which includes most of Earths history began with?
The Precambrian time, which includes the majority of Earth's history, began approximately 4.6 billion years ago with the formation of the Earth. This time period encompasses about 88% of geologic time and is divided into the Hadean, Archean, and Proterozoic eons.

Is the Earth's surface hot or cool in the Precambrian Time?
During the Precambrian time, the Earth's surface was generally hotter compared to present day, due to higher levels of volcanic activity and lower levels of atmospheric oxygen. This period experienced intense tectonic activity, leading to the formation of supercontinents and widespread geologic changes.
What happen during the Precambrian time period?
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
What period did the Rock of Precambrian shield form?
The Rock of Precambrian shield formed about 4 billion years ago during the Precambrian period. It is one of the oldest geological formations on Earth, characterized by its ancient rocks and lack of fossils.

Where was precambrian era?
The Precambrian era was a geological period that spanned from about 4.6 billion years ago to around 541 million years ago. It encompasses the earliest part of Earth's history, including the formation of the planet and the evolution of life forms. The Precambrian era was followed by the Paleozoic era, which marked the beginning of complex life on Earth.
What are the Preambrian plants?
During the Precambrian period, plants had not yet evolved. The Precambrian period is characterized by simple life forms like bacteria and algae. Land plants did not appear until the Ordovician period, which followed the Precambrian.
