Why are more fossils found in the paleozoic era than in the precambrian era?

During the Precambrian times, life was mostly limited to single celled organisms. Life that was not single cellular didn't have any hard body part (like teeth, bones, shells, etc.) and so they weren't preserved.

∙ 9y agoThere are many fossil records from the Precambrian era because there are so many stromatolites buried.

What have scientist inferred from fossil stromatolites?
Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
Which era contains fossils of dinosaurs?
Primarily during Cambrian, from 600 million years ago.
What paleoclimatic evidence supports the idea of the late Paleozoic super continent in the Southern Hemisphere?
fossil evidence - identical fossils in different continentrock type and structural similarities - found similar rocks on continents on opposite sidesstudy of climate - the heat of the sunRead more: What_evidence_is_there_to_support_the_existence_of_a_super_continent
How fossils are layered?
We Find fossils Inside the Mud or soils deep end... The more deep ... The more you get fossils The more Near.. The less chances or formation of Fossils..
Is aragonite more likely to be found in younger or older fossils?
Aragonite only occurs in fossils of the Cainozoic era as the unstable polymorph aragonite rearranges its chemical structure to form more stable Calcite over time.
What have scientist inferred from fossil stromatolites?
Stromatolites were much more abundant on the planet in Precambrian times which means that fossils found around stromatolites are typically from the Precambrian era.
Why is Precambrian history more difficult to study than more recent geological history?
no fossils of organisms with hard parts. the few soft body part fossils found rarely fossilize well.

Why aren't most of the found fossils complete organisms?
because fossils are rare to find and in complete form even more rare only 10% or less out of 100% fossils have been found on earth
How long did the PreCambrian era last?
The Precambrian Era. The name means: "before the Cambrian period." This old, but still common term was originally used to refer to the whole period of earth's history before the formation of the oldest rocks with recognizable fossils in them. In the last few decades, however, geologists have found that there are some hard-to-discern fossils in some Precambrian rocks, so this period is now also known as the Cryptozoic or "obscure life" Eon (from the words "crypt" = "hidden," and "zoon" = "life"). The Precambrian covers almost 90% of the entire history of the Earth. It has been divided into three eras: the Hadean, the Archean and the Proterozoic. Source: Unknown The Precambrian Era comprises all of geologic time prior to 600 million years ago. The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period. It is now known, however, that life on Earth began by the early Archean and that fossilized organisms became more and more abundant throughout Precambrian time. The two major subdivisions of the last part of the Precambrian are the Archean (oldest) and the Proterozoic. Rocks younger than 600 Ma are considered part of the Phanerozoic.
Which kind of organism is more like to be found as a fossils is Amber?
Insects.
Are there more than 4 australopithecus africanus fossils?
Only four fossils of australopithecus africanus have been found, as yet (2012).
Fossils preserved in ice or snow?
Fossils that have been preserved in ice or snow are known as frozen fossils. Generally, frozen fossils are associated with plants and animals that lived during the Ice Age.
Why are animal fossils more abundant from the Cambrian Period than from the earlier periods?
Because Paleozoic era rock is much older than Mesozoic era rock, these strata are generally at greater depth than Mesozoic rock, thus limiting their accessibility to areas that have been exposed by weathering and erosion.
What is the type of skin dinosaurs have?
Some had scales, but more and more dinosaur fossils are being found with feathers.
Have More Human Fossils Have Been Found Than Any Other Type Of Fossil?
No, human fossils are among the rarest type of fossils. Fossils of plants and marine organisms are far more abundant and have been found in greater numbers than human fossils.
