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 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.
The second era in geological time?
The second era in geological time is the Paleozoic era, which lasted from about 541 million years ago to 252 million years ago. It is known for the evolution of early marine life, the colonization of land by plants and animals, and the formation of the supercontinent Pangaea. Major events during this era include the Cambrian explosion, the colonization of land by plants during the Silurian period, and the mass extinction at the end of the Permian period.
Which era of geologic history marks a time when life rapidly became more complex when marine life became more diverse and plants first emerged on Earth?
The era that marks a significant increase in the complexity of life, particularly with the diversification of marine life and the emergence of plants on Earth, is the Paleozoic Era. This era began around 541 million years ago with the Cambrian Period, known for the "Cambrian Explosion," when many phyla of marine organisms rapidly evolved. The Paleozoic also saw the first land plants appear, contributing to the complexity of ecosystems.
What geologic time period was the trilobite fossil associated?
Trilobites were associated with the Paleozoic era, from the Cambrian to the Permian.
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 the beginning of the Paleozoic era marks?
The start of the Paleozoic Era was marked by a huge diversification of life known as the Cambrian Explosion. Many genre of life emerged during the Cambrian Period. Although plants and animals were around in the Pre-Cambrian it was not until after the extinction event that immediately proceeded the Paleozoic that many advanced forms of life evolved such as multi-celled plants and advanced animals such as the arthropods.
In what era did jellyfish evolve?
Jellyfish and other multi-cellullar organisms evolved during the Cambrian era.
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 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 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.
The second era in geological time?
The second era in geological time is the Paleozoic era, which lasted from about 541 million years ago to 252 million years ago. It is known for the evolution of early marine life, the colonization of land by plants and animals, and the formation of the supercontinent Pangaea. Major events during this era include the Cambrian explosion, the colonization of land by plants during the Silurian period, and the mass extinction at the end of the Permian 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.
When did life begin to appear on earth?
Plants have been around on the Earth since the Cambrian part of the Palenzonic Era.
What time period was the creature trilobite in?
Trilobites originated during the Cambrian era, flourished through the Paleozoic era, declined during the Devonian era, and finally became extinct in the Permean mass extinction event. In total there were live trilobites on the earth for about 290 million years.
What is the nature of rock during Pre Cambrian Era?
AnswerThe same three rock types existed in the Pre-Cambrian as exist today: sedimentary, igneous, and metamorphic. The main difference was that in the Pre Cambrian there were no large animals. As a result, there were no coral reef to make limestones. The Pre Cambrian is a very long period of time though (4 billion years). There are some major differences between early and late pre Cambrian rock.
This is the second era in geologic time?
The second era in geologic time is the Paleozoic Era, which lasted from about 541 million years ago to 252 million years ago. It is known for the Cambrian explosion, the development of complex multi-cellular life forms, and the presence of early terrestrial plants and animals. Major events in this era include the colonization of land by plants and arthropods, as well as the diversification of marine life.
