What geologic period has fossils of the most primitive lifeforms?
cambrian
Was the Cambrian explosion a volcanic eruption?
No, the Cambrian explosion was not a volcanic eruption. It was a period of rapid diversification of multicellular lifeforms that occurred around 541 million years ago, marking the beginning of the Paleozoic era.
Is of the major animal body plans seen today appeared in the fossil record over 500 million years ago at the beginning of what period?
The major animal body plans seen today appeared in the fossil record over 500 million years ago at the beginning of the Cambrian Period. This period is known as the Cambrian Explosion, during which a wide variety of animal forms emerged and diversified rapidly.
Why were there no plants during the Cambrian time era?
There were simple plants in the Cambrian Period(542 - 488.3Ma). Fossil algae has been found in Cambrian Rocks. Evidence of primitive algae from the Precambrian Super-Eon has also been found but exact classification has not been established. It is true that embryophytes (Plants we most recognise) did not evolve until the Ordovician Period(488.3 - 443.7Ma).
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.

The Ordovician period came after the Cambrian period.
During which period in the geologic time scale was there a great increase in the variety of life forms on earth?
The Cambrian Period, approximately 541 million years ago, is known as the "Cambrian Explosion" because of the rapid diversification and increase in the variety of life forms on Earth during that time. This period saw the emergence of most major groups of animals that exist today.
Which type of organism appeared for the first time during the Cambrian period?
Trilobites
When in the devonian period were fish developed?
Fish first appeared in the Cambrian period, long before the Devonian.
What are some plants from the Cambrian period?
The only plant from the Cambrian period is algae.
What era did the Ediacaran Fauna Live?
The Ediacarian fauna are from the Cambrian Explosion. The Cambrian Explosion occurred in the Cambrian period. The Cambrian period was part of the Paleozoic era.
What is Cambrian?
The Cambrian is a period of time which comes after the vendian millions of years before dinosaurs it was hotter than the Sahara with no plants or animals on land only in the seas.Geologists name the different periods of the earth's development. Adam Sedgwick named the period within the Paleozoic era the Cambrian period. The Cambrian period occurred millions of years ago and represents the first geological period of this era. During this time, living organisms evolved to be more complex than the formerly known single cellular types.
Did flowers first appear in the Cambrian period?
No. Answer No, flowering plants (angiosperms) first appeared (as far as we know) in the Cretaceous period.
