What are the differences between the Cambrian and paleozoic fauna?

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.

Why is it important to scientists that many organisms during the Cambrian period had hard parts?

Referred to the Cambrian explosion is the Cambrian period. Shells and exoskeletons had hard parts. The Cambrian period was the first of the Paleozoic Era.The hard parts made the preservation of their shapes, and sometimes their body cavities, much more easy to recognize as a fossil. The earlier soft bodied organisms required very fine silts for their effective preservation. A representative group they found are the Ediacaran fauna.

What are differences in animals called?

living creatures

Differences between Australian rainforest and foreign rainforest?

What are the differences between the paleozoic mesozoic and Cenozoic eras?

The Paleozoic, the Mesozoic and the Cenozoic are the 3 Eras of the Phanerozoic Eon.The Paleozoic Era occurred between 542 and 251 million years ago. It lasted 291 million years. It was made up of 6 geological periods. The Cambrian Period(542 - 488Ma), the Ordovician(488 - 443Ma), the Silurian(433 - 416Ma), the Devonian(416 - 359Ma), the Carboniferous(359 - 299Ma) and the Permian(299 - 251Ma).The Mesozoic Era occurred between 251 and 65.5 million years ago. It lasted 185.5 million years. It was made up of 3 geological periods. The Triassic Period (251 - 199.6Ma), the Jurassic(199.6 - 145.5Ma) and the Cretaceous(145.5Ma).The Cenozoic Era occurred between 65.5 million years ago to now. It has lasted 65.5 million years to date. It has been made up of 3 geological periods to date. The Paleogene(65.5 - 23.03Ma), the Neogene(23.03 - 2.588Ma) and the current period the Quaternary Period (2.588Ma - Now)

What is ediacaran?

Ediacaran fauna are the fossil animals found in rocks dated around 650-540 million years ago, just before the Cambrian period.

What is the difference between fauna and habitat?

Fauna is an animal - habitat is where it lives.

Why did the Ediacara fauna thrive during the Cambrian Period even though they were immobile?

They didn't thrive in the Cambrian, they are very rare and not necessarily the same biologically as the forms in the Precambrian. Soft bodied preservation in the Ediacaran style occurs throughout the Phanerozoic, but becomes increasingly rare after the Cambrian- perhaps due to disturbance of bedding surfaces by metazoans, but there are many other possibilities.

Difference between flora and fauna?

Flora means plants fauna means animals

Is Ayers rock a sedimentary igneous or metamorphic?

No. The Ediacara fauna / fossils are considered pre Cambrian. But if you really want to know about old rocks, have a crack at zircons.
