One reason fossils are rarely found in Precambrian rocks is that?
Precambrian rocks contain relatively fewer fossils than rocks from different eras. This may be due to the fact that the rocks from this era were subject to a lot of heat and pressure, or were exposed to erosion.
Which factor prevents us from finding precambrian fossils?
Most rocks from that era are deeply buried.
What is Archean Era?
The Archean era is the earliest Precambrian era, archean means "ancient" or "beginning". The Archean era starts with the oldest known rocks, about 4.6 billion years ago.
Did the precambrian era occur first?
Yes. The first era was the precambrian era followed by the paleozoic era then the mesozoic era than the Cenozoic era.
What was the longest era?
Precambrian
Why is the shield also referred to as the Precambrian Shield?
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.
What would you see during the Precambrian era?
just rocks and blobs of jelly
