Which type of organism appeared for the first time during the Cambrian period?
Trilobites
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).
The appearance of the most complex and the greatest diversity of organisms occurred during what time period?
The appearance of the most complex and the greatest diversity of organisms on Earth occurred during the Cambrian Period, around 541 million years ago. This period is known as the "Cambrian Explosion" due to the rapid diversification of multicellular life forms.
What are the eras of the CAMBRIAN?
The Cambrian Period is divided into three eras: the Early Cambrian, Middle Cambrian, and Late Cambrian. These eras refer to different stages or time intervals within the Cambrian Period, which lasted from about 541 to 485 million years ago. Each era is characterized by different geological and biological events, including the diversification of early animal life.
What phylum was dominant during the Cambrian Era about 540 million years ago?
During the Cambrian Era, the dominant phylum was Arthropoda, which includes ancestors of modern insects, crustaceans, and arachnids. This period saw a rapid diversification of life forms in what is known as the Cambrian Explosion, leading to the emergence of many major animal phyla. Other significant phyla during this time included Mollusca and Annelida. The Cambrian period marked a crucial evolutionary step, setting the foundation for complex life on Earth.
Which type of organism appeared for the first time during the Cambrian period?
Trilobites
What was the latitude of north America during the Cambrian time period?
that is what i want to know
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.
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.
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 time period would a brachiopod be alive?
Brachipods evolved about 540 million years ago during the Cambrian period. They still exist today, so they also were alive during all of periods between now and the Cambrian.
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.
What danger were in the Cambrian period?
During the Cambrian period, marine life faced dangers such as predation by early predators like anomalocaridids and trilobites. Competition for resources and environmental changes also presented challenges to organisms during this time.
Why were there no plants during the Cambrian time era?

What did the earth's surface look like during the Cambrian time period?
it was one massive island surrounded by water
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.
Were there plants in the Cambrian time period?
No. Primitive algae existed but true plants did not. There was no life on land in the Cambrian.
