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.
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 the odds that evolution is true?
ANSWERS * There are countless evidences for micro-evolution, that is, adaptations of species; scientists believe this also occurred as macro-evolution, the development of new species. There is also substantial evidence for natural selection, the survival of species that are best adapted to their environment. Evolution does not address the origin of life. Beyond that, it would certainly be difficult to show conclusively that evolution is the sole explanation for the development and survival or extinction of species. * Evolution is far and away the best explanation for all the facts regarding life on earth and the changes it has undergone. Evolution, the idea that life has been here on earth and has been changing over millions of years, is fact. Darwin's tree of life is real, and fact-proven. The facts of evolution are presented in modern evolutionary synthesis (MES). There is a mountain of facts that are stacked up behind MES. The evidence is overwhelming. Note that it is not a question of the facts supporting MES, but rather MES explains all the many facts we have gathered about life on earth, about its tenure here and the many changes it has gone through over the billions of years since it began. [And evolution doesn't say man evolved from monkeys. It only says we have a common ancestor. It is a good idea to check facts before arguing against a point of view.] It should be fairly noted that MES offers no proof whatsoever regarding abiogenesis (the creation of life). There is no physical evidence of any kind that speaks to the animation of mud by lighting. Only a number of theories are set out to offer what might have happened. In the mean time, anyone who is sitting in biology and learning about evolution is learning scientific fact. Life has been on earth for billions of years, and it has been changing against the backdrop of a changing earth for all that time. If life did not change when the earth did, that life died. It's that simple. Evolution as it is presented in modern evolutionary synthesis is fact. And the vast majority of scientists and scientific organizations worldwide are in agreement. This is what is currently taught in biology class, and correctly so.* Scientists find apparent evidence of macro-evolution everywhere in the fossil record. One example of an apparently transitional species is the 380 million-year-old fossil of a primitive fish, Gogonasus. It had fins some scientists believe were strong enough to support its weight in shallow water and propel itself along. A scan of the fossil, using a three-dimensional X-ray microscope, revealed its skeleton had several features that were like those of a four-legged land animal, or tetrapod. They included a structure similar to one of the bones of a middle ear; and there were arm-like bones in its fins:the radius and ulna, as are also in the pectoral fins of whales. Here was a fish that seems to have evolved to a point where it had much in common with later land animals. * No, there are also evidences that indicate evolution is not true. There are many biological organisms and organs that appear to be irreducibly complex, such as the eye. Which part of the eye could have evolved first from accidental mutation? Why did it survive natural selection--what use was it without the rest of the eye? These evidences are not accepted as valid arguments by evolutionary scientists.* Macro-evolution -- the development of entirely new species from existing ones, such as dinosaurs evolving into birds -- has no indisputable evidence. Can you observe it? No. Can you demonstrate it? No. The evidences offered tend to be of the noted similarities variety and without an intelligent intervention, evolution is the only explanation that seems to work. Adaptations merely show selection for traits already present in the gene pool. There is no evidence for addition of complex design information, such as would be required for amoeba to human evolution. The opponents of evolution would claim that the similarities could as easily be evidences of common design.* Of course we can not observe macro-evolution taking place, simply because the timescales are too long. But we can demonstrate it. In the example suggested above by a skeptic, the evolution of dinosaurs into birds, scientists have found rock impressions of dinosaur bodies, showing the presence of feathers. Of course the dinosaur in question did not use feathers to fly, but to keep warm. And Archaeoptrix was a dinosaur, but it was also almost a bird.* There's a reason they call it the Theory of Evolution - that means that even the people who believe in it 100% know it can't be proven. * Despite over 70 years of militant teaching that evolution is true, there have been no, count it, no definitive correlations between this theory and fact. Despite the wishful thinking of the evolutionists, there has been no proof that Darwin's Origin of the Species was correct. Short version...my ancestors were men...Darwin's might have been apes, but there's no proof. * Not only is there no evidence that evolution is true the switching of terms to make it sound true only hides the fact, it doesn't make it any more true. The reference here is to the proven fact that organisms change in response to their environment. This is called natural selection but it is not evolution as the organism does not evolve into anything else. It merely uses the genetic information in its gene pool to either adapt, or in some cases unfortunately, it becomes extinct. There is no evidence that species change into something else. Genetics demonstrates that there are definite limits to change. To equate natural selection with evolution is pseudo-science.* Evolution is widely regarded as fact by virtually all earth and life scientists, some of whom are Christian. Evolution unifies and explains hundreds of thousands of facts in several areas of science extremely elegantly, it allows us to predict with startling accuracy where we will find fossils, how old they will be when we find them, what they will look like and why, and allows us to fight disease by using evolutionary principles to determine how diseases will evolve over time. Evolution is observed at every level, from natural selection to speciation (the formation of new species).* Apart from their being no evidence that evolution is true there is also much evidence that directly contradicts various aspects of evolutionary dogma.
When did the most recent Ediacaran organism live?
The most recent Ediacaran organism is said to have lived prior to 1946 after fossils were found.
Which era did the ediacaran live in?
The ediacaran fauna lived during Precambrian time and became extinct then, too. Nobody knows for sure why, but trilobites might have caused their disappearance.

When did the ediacaran fauna exist?
The ediacaran fauna lived during Precambrian time and became extinct then, too. Nobody knows for sure why, but trilobites might have caused their disappearance.
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's the vendian period?
The Vendian Period is a time period in geologic history that lasted from 650 - 543 million years ago. The Vendian is also known as the Ediacaran or as the Proterozoic.
The most common fossils that occur in precambrian rocks are?
The most common pre-Cambrian fossils were soft bodied animals that lived between 542 and 600 million years ago. These were called Ediacaran biota and Vendian biota.
Can a jellyfish fossilize?
Only under unusually specific conditions would a soft-bodied creature such as a jellyfish be capable of making a fossil. If deposited in an extremely fine suspension of mud, and presuming that there were no scavenging organisms present. Such fossils are known, and you'll find some data in wikipedia under Ediacaran.

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.
Can you find fossil remains of a jellyfish or a worm?

If deposited in an extremely fine suspension of mud, and presuming that there were no scavenging organisms present. Such fossils are known, and you'll find some data in wikipedia under Ediacaran.
Is precambrain the oldest era?
No. The 'pre' bit merely means before. Similarly one may speak of post mesozoic, where 'post' means after. Within the period before the Cambrian, (when hard bodied entities first appeared), there are several named glaciations, and also some era defined by the soft bodied organisms found there. e.g the Ediacaran named after a location in Australia. The faunal group is called Ediacara.
Why is it important to scientists that many organisms during the Cambrian period had hard parts?
