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).
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.
Was life not very diverse during the Cambrian period?
The Cambrian period was marked by a rapid diversification of life known as the Cambrian explosion, where many new body plans and major animal groups appeared. This period saw the emergence of various marine organisms with complex body structures, leading to a significant increase in biological diversity.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
Were there herbivores during the Cambrian time period?
Yes, there were herbivores during the Cambrian period. Some early marine organisms, such as trilobites and some primitive arthropods, are believed to have been herbivorous, feeding on algae and other organic matter present in the oceans at that time.
What phylum was not present during the Cambrian period?
The phylum Cnidaria was not present during the Cambrian period. Cnidarians, which include jellyfish and corals, appeared later in the fossil record during the Ediacaran period and diversified in the subsequent periods.
Is where trilobites and brachiopods appeared?
Trilobites and brachiopods first appeared during the Cambrian period, around 541 million years ago. They were both abundant and diverse in the ancient oceans, contributing to the biodiversity of marine life during that time.

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.
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.
What is the cambrain explosion?
life during the early Cambrian period
Was life not very diverse during the Cambrian period?
The Cambrian period was marked by a rapid diversification of life known as the Cambrian explosion, where many new body plans and major animal groups appeared. This period saw the emergence of various marine organisms with complex body structures, leading to a significant increase in biological diversity.
What is the significance of the didvision between the Cambrian and PreCambrian periods?
During the Cambrian period, life began to appear on the planet.
Where were most of the continents during the Cambrian period?
During the Cambrian period, known as the "Cambrian Explosion," most continents were part of a supercontinent called Gondwana, situated in the Southern Hemisphere. North America and Europe were closer to the equator at this time.
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.
What period came after the Cambrian period?
The Ordovician period came after the Cambrian period.
What is a sentence using the word Cambrian?
This refers to a period of time during the Paleozoic Era. Here are some sentences.The Cambrian Period was the first 65 million years of the Paleozoic Era.Trilobites flourished during the Cambrian.The Cambrian was characterized by warm seas and deserts on land.
