Cambrian period
What geologic period has fossils of the most primitive lifeforms?
cambrian
Fossils of fish appeared approximately 500 mya during the what?
Fossils of fish appeared approximately 500 million years ago during the Cambrian period. This period saw the rapid diversification of life forms in the oceans, including the development of early fish species.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
Which type of organism appeared for the first time during the Cambrian period?
Trilobites
What shelled creatures developed in the Cambrian Period leaving behind excellent fossils?
Trilobite
When did presumed animal fossils first appear?
The presumed animal fossils first appeared during the Archaean Cambrian period. There is no clear indication why they appeared this late into history.

Cambrian period

When did large numbers of fossils first appear in the geologic record?
Large numbers of fossils begin to appear around 530 million years ago. It is called the Cambrian Explosion, because it occurred in the Cambrian period. The Cambrian period was the first part of the Paleozoic era.
Fossils of fish appeared approximately 500 mya during the what?
Fossils of fish appeared approximately 500 million years ago during the Cambrian period. This period saw the rapid diversification of life forms in the oceans, including the development of early fish species.
What organisms did the Cambrian explosion make?
First of all, the Cambrian Explosion is designated as a huge diversification event taking place between 543 to 506 MYA, when most of the phyla extant (living) today appeared. So the first chordates, shelled organisms and arthropods were seen in the Cambrian period. Therefore, complex bilateria dominated the Cambrian scene.
The first fossils of land plants and animals are found in rocks from the?
Cambrian Period Actually the correct answer to this question is the "Pennsylvanian Period".
What is the index fossil of the Cambrian?
Trilobites are one of the index fossils commonly found in Cambrian rock layers. These ancient arthropods lived in the seas during the Cambrian period and are used by geologists as markers for dating rocks from that time period.
What does the term Cambrian Explosion mean?
The sudden appearance of most of the major animal phyla within the fossils early in the Cambrian period. This caused a sudden diversification of life.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
During what period did the first vertebrates appear?
The first vertebrates evolved during the Cambrian Explosion about 525 million years ago. The Cambrian Explosion, obviously, occurred during the Cambrian period. The Cambrian period was part of the Paleozoic era.
