Why is it unlikely that fossils would be found in igneous rock?
Fossils are unlikely to be found in igneous rock because igneous rock forms through the cooling and solidification of molten rock, which destroys any fossils that may have been present. Most fossils are found in sedimentary rock layers where the remains of plants and animals can be preserved over time.
When does a fossil become a fossil?
A fossil is formed when organic remains are slowly replaced by minerals, preserving the structure. The process can take thousands or millions of years. Once this transformation is complete, the organic material is considered a fossil.
Why are fossils found in sedimentary rock?
Sedimentary rocks can contain fossils because, unlike most igneous and metamorphic rocks, they form at temperatures and pressures that do not destroy fossil remains. Dead organisms can become sediments which may, under the right conditions, become sedimentary rock.
Igneous rock forms from magma; no chance for fossils to form there. Metamorphic rocks are other rock types that are changed by heat and pressure; their transformation and mineral reorganization causes very few fossils to be found there. Sedimentary rock can be formed from the accumulation of sediments and are often formed near ancient shores, basins, and lake beds. If an organism dies and is covered by sediments before being rotted or eaten by predatory organisms, it could eventually become part of the sedimentary layer that becomes rock.
How does the law of superposition allow paleontologist to assign relative ages to fossils?
The law of superposition states that the lower down the layer of rock (also called strata) in the ground, the older it is. Therefore, if the fossil is located in a specific strata that is a certain depth beneath the ground it is conclusive as to about how old the fossil is.
Fossils cant tell us the colour of the animal or plant which is fossilised
fossils cant tell us the future of the year of 2013 whichwe both no is not gonna happen or u can go with her or his answer
In Pokemon emarld where is doven he research on reviving Pokemon fossils?
In Pokemon Emerald, the researcher on reviving Pokemon fossils is located in the Fossil Maniac's house in Fallarbor Town. You can find him by entering the house and interacting with him to revive fossils into Pokemon.
Fossils found in the lowest geological strata are gerenally the most?
Fossils found in the lowest geological strata are generally the oldest. This is because the law of superposition dictates that older rock layers are found at the bottom, with each successive layer above being younger. Therefore, fossils found in lower strata are older than those in higher strata.
Over time what type of fossil is formed when thin objects are trapped in mud?
Thin objects trapped in mud can form trace fossils, such as worm burrows or footprints, which show evidence of the organism's activity rather than the organism itself. These trace fossils can provide important information about the behavior and ecology of ancient organisms.
Is it possible for granite to have fossils or shells in it?
Yes, it is possible for granite to contain fossils or shells. This occurs when sedimentary rocks containing fossils or shells are metamorphosed and transformed into granite over time. The original fossils or shells may be preserved within the granite, although they may be altered or distorted due to the intense heat and pressure of the metamorphic process.
Why are mussels not found on sandy seashores?
Mussels require a hard substrate to attach themselves to, such as rocks or other hard surfaces, in order to thrive. Sandy seashores do not provide the structural support needed for mussels to attach and grow successfully. Additionally, sandy environments do not offer the stable conditions mussels need to withstand waves and currents.
Fossils that can be used to establish relative dates are most likely to be found in?
Sedimentary rocks, which form in layers over time, are most likely to contain fossils that can be used to establish relative dates. Fossils found in these rocks provide a record of the organisms that lived at specific times in Earth's history, allowing scientists to determine the relative age of the rock layers.
Darwin's idea of common descent and natural selection posits that all living organisms share a common ancestor and that genetic changes that improve an organism's ability to survive and reproduce are passed down to future generations. This forms the basis of his theory of evolution.
They aren't fragile but they are brittle. Fossils are mineral crystalisations of decayed organic matter. Basically they are rocks.
How many dinosaur fossils have been found?
Nobody knows how many for sure, but there are certainly thousands.
You've got to remember, fossils aren't necessarily whole skeletons, they might be sections of bone, a single tooth, a fossilised egg, or even a whole nest. Sometimes we get lucky and find whole skeletons, or even scenes from the past, such as a mother looking after her eggs, who died in a sandstorm, or a triceratops and a velociraptor who both died from the wounds they inflicted on each other, fossilised as a single scene, locked in combat even in death.
There are so many different varieties of dinosaur that we have discovered, and so many examples of each species, or pieces of examples, that we can't possibly be sure how many there even are. Some people say we have even only discovered 1% of all dinosaur species! So sorry, no-one really knows.
Hope this helped! :)
Most age dating assumes that the sediment is deposited uniformly, that nature works at a constant rate over time. This is obviously not true because we see sudden changes in nature every day, earthquakes, tsunamis, floods, landslides, etc., all of which affect the estimates.

lions over years also..they havent ever started it over
What are the most common precambrian fossils called?
The most common Precambrian fossils are stromatolites. These are layered structures formed by the growth of cyanobacteria, also known as blue-green algae, in shallow water environments. Stromatolites are important in understanding early life on Earth.
Where was the Megalania fossil found?
Megalania fossils have been found in various locations in Australia, mainly in the eastern and southeastern parts of the country. One of the most significant finds was in the Naracoorte Caves in South Australia.
How do you search a serial number for a fossil watch to check its value?
There are two or three ways to check the secondary value of items. One way is to get a book listing the secondary market value of the item you want to check. In this case you would find a book on watches that list Fossil watches. Another way is to go on EBay and do a search. Find an item that is like the one you have and see what it is selling for or what is the listing price. This will give you an approx. value. The final way is a bit harder and you take your watch to someone to have it appraised. This could cost you a few dollars, probably more than what the watch is worth. Any one of these methods will give you a value of some sort. Many things don't sell on the secondary market unless there is a need or a collector who is looking for that item. The prices on the market also go up and down just like stock.
How far back does the fossil record extend?
Hard-bodied animals date back to the Cambrian era, about 540 million years ago.
However there are earlier advanced soft fossils found in recent years at places like Ediacara in Australia.
However, algae are known from about 3 billion years ago. These guys were the ones which invented photosynthesis, the important bit of which is splitting water into H and O. The O they discharge as waste, and the H they use to make complex biochemicals. When they evolved, the O2 component of the atmosphere was only a few%, and contained much CO2 and methane.
With their new trick of photosynthesis, the algae were able to mop up all (well, most of) the methane and CO2, and when these greenhouse gases disappeared, the world went into a Snowball Earth phase which lasted for a billion years or so, and the oceans were frozen at the Equator.
Much of the iron in the oceans which had been in solution, was precipitated out as iron oxide, and these form the banded iron deposits of great economic importance today.
But the volcanoes were still operating, and the methane and CO2 continued to increase, and eventually raised the temperature of the Earth.
The algae come in brown, red, and green varieties, and all our green plants may have descended from the green algae.
At the level of speculation, siderophile bacteria (which love iron) may have formed on the ocean bottom near Black Smokers, and these may evolve on iron-sulfur hydrothermal vents. These areas are rather inaccessible, and only in recent years have these speculations been offered.
Where were fossils of the earliest human ancestors?
Fossils of human and human-like remains have been found all over the world with no clear chronology. For instance, remains which are dated at one time are found with a more human brow and remains are dated much later with a less human brow, but another more human trait. The problem then is distinguishing the chronology of "earliest" at the same time that human-ness is debatable. A recent arcticle mentioned a "human" ancestor which was the size of a large dog and looked like an anteater. So, in the absence of continuous and complete fosil record, evolutionists are free to claim any definition of chronology and humanity which suits their individual research. That being said most experts agree that the first humans came out of Africa.

How do you make the fossils come back to life in sapphire?
Go to Rustboro City and to the Devon Corp building. On the second floor one of the guys will offer to restore it. Just go up or down a set of stairs and he will be finished and give it to you. Root fossil-lileep Claw fossil-anorith
Yes, fossils can form in ice. This process is known as cryogenic fossilization, where the remains of organisms are preserved in ice over long periods of time. This type of preservation provides scientists with valuable insights into ancient ecosystems and species that lived in cold environments.
1 What conditions must exist in order for fossils to form?
Fossils form when an organism is buried quickly after death in sedimentary rock, allowing the hard parts of the organism to be preserved over time from being compressed and mineralized. The burial process must protect the remains from decomposition and physical damage.
