The layer of sandstone must be younger than the layer of limestone, which contains the 300-million-year-old fossil. Since there are no unconformities, the sandstone was deposited after the limestone, meaning it formed after the fossilizing event of the limestone layer. Therefore, the sandstone is younger than 300 million years old.
What else can I help you with?
If a layer of sandstone lies on top of a layer of limestone in which a 300-million-year-old fossil is found and there are no unconformities the layer of sandstone must be .?
The layer of sandstone must be younger than the layer of limestone. Since the limestone contains a 300-million-year-old fossil, it indicates that the limestone is older than 300 million years. Therefore, the sandstone, which lies on top without any unconformities, must have formed after the limestone was deposited.
What is an animal fossil buried in?
An animal fossil can be buried in sedimentary rock layers such as sandstone, shale, or limestone that have accumulated over time. The fossilization process occurs when the remains of an animal are buried quickly after death, protecting them from decay and allowing for the formation of a fossil.
How can scientists use a chemical reaction to separate a fossil from limestone without damaging the fossil?
The limestone containing a fossil would be heaated to a sufficiently high temperature (about 1,800 centigrade).then the limestone would become powder and the fossil which is not as sensitive to heat as limestone would remain un damaged
What could take a layer of limestone away from a fossil?
If the fossil is replaced with silica the easiest way to remove the limestone is with weak acid such as vinegar. If the fossil is also limestone the best way to free it is by carefully removing the limestone with small picks and drills. This is usually best left to expert conservators as it can be delicate work.
What is the best type of rock for fossil formation?
Sedimentary rocks (such as shale, sandstone, and limestone) are the best types of rock for fossil formation. These rocks are formed from layers of sediment that can preserve and protect fossils over time. Additionally, the fine-grained nature of sedimentary rocks allows for the detailed preservation of fossils.

What are some examples of fossil rocks?
Fossils rocks are sedimentary rocks such as coal, limestone, sandstone, and shale.
Is sandstone a fossil?
A fossil is the preserved remains of an animal, plant or other organism while sandstone is a type of sedimentary rock. There is a fairly distinct difference between the two, thus sandstone is not a fossil. Sandstone may have fossil inclusions, but we are talking about two different things regarding fossils and sandstone.
What is an animal fossil buried in?
An animal fossil can be buried in sedimentary rock layers such as sandstone, shale, or limestone that have accumulated over time. The fossilization process occurs when the remains of an animal are buried quickly after death, protecting them from decay and allowing for the formation of a fossil.
What type of rock are you most likely to find a fossil?
You are most likely to find them in sedimentary rock.
How can scientists use a chemical reaction to separate a fossil from limestone without damaging the fossil?
The limestone containing a fossil would be heaated to a sufficiently high temperature (about 1,800 centigrade).then the limestone would become powder and the fossil which is not as sensitive to heat as limestone would remain un damaged
What is the difference between fossil rich limestone and chemical limestone?
fossil rich limestone is made by the earth and is enhance with fossils although the chemical is man made, the two are basically the same.
What kind of rock would be most likely to find a fossil sandstone or marble?
Sandstone. Sandstone is a sedimentary rock - which is the only type of rock which can contain fossils.
Is sandstone a fosil fuel?
No, sandstone is not a fossil fuel. Sandstone is a type of sedimentary rock formed from sand-sized grains of minerals, while fossil fuels are natural resources like coal, oil, and natural gas that are formed from the remains of living organisms over millions of years.
How sandstone shale and limestone form?
Limestones are form by precipitation of rusually under water Sandstones are formed from sendiments that are being eroded and compacted and cemented together. Shale are formed from precipation also but you often see fossil records on them.
What could take a layer of limestone away from a fossil?
If the fossil is replaced with silica the easiest way to remove the limestone is with weak acid such as vinegar. If the fossil is also limestone the best way to free it is by carefully removing the limestone with small picks and drills. This is usually best left to expert conservators as it can be delicate work.
What is fossil rich limestone?
Fossil rich limestone is limestone with various sea creature fossils in it such as shells. It is organic and fine grained. It is sedimentary... Yea that's it :P
