At the beginning of the Cambrian period, approximately 541 million years ago, a significant evolutionary event known as the "Cambrian Explosion" occurred. This period marked a rapid diversification of life, where many major groups of animals, including arthropods, mollusks, and early vertebrates, emerged in the fossil record. The development of hard body parts, such as shells and exoskeletons, allowed for better fossilization, leading to an abundance of preserved specimens. This dramatic increase in biodiversity set the foundation for modern ecosystems.
The Ordovician period came after the Cambrian 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.
The beginning of the Cambrian period is marked by the Cambrian Explosion, a rapid diversification of life forms that occurred around 541 million years ago. This event led to the sudden appearance of a wide variety of complex multicellular organisms in the fossil record, setting the stage for the subsequent evolution of life on Earth.
The Cambrian period occurred approximately 541 million years ago, marking the beginning of the Paleozoic Era. The Pre-Cambrian is a broad division of time before the Cambrian period, encompassing about 4 billion years of Earth's history, including the formation of the planet and the evolution of life prior to complex multicellular organisms.
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.
In the Cambrian period, the world's oceans were beginning to form because the glaciers were melting. Most of the world's land was in the Southern Hemisphere.
The Ordovician period came after the Cambrian period.
The Cambrian Period was from about 543 to 490 million years ago. It is the earliest period in the Paleozoic ("old life") Era. Until relatively recently paleontologists thought this marked the beginning of life. Primitive life is now know from the Pre-Cambrian Eon.

The only plant from the Cambrian period is algae.
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.
The Paleozoic Era has seven Periods beginning with the Cambrian Period. The last period was the Permian Period which was from 290 Million to 248 million years ago.
There was no language used in the Cambrian period. Humans had not yet evolved.
Haikouichthys and Myllokunmingia were two vertebrates in the Cambrian Period
