fossils almost allways occur in sedementary rock. this is the only way to get fossils without burning or cruching the fossil. you sometimes get fossils in igneous rock, but this is very rare. igneous rock fossils do not have any actual "fossils" in them, they are just impressions.

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 happens to a fossil in a sedimentary rock when that rock becomes a metamorphic rock?
It will become misshapen or its constituent minerals may realign, recrystallize or form new minerals. In any event, the most likely occurrence is that the fossil will no longer be recognizable.
Which rock consists mostly of pieces of seashells?
Marine shells could be found in a variety of rocks, all of which would be of the sedimentary classification. Limestone would typically most often contain shells or shell fragments. A type of limestone containing abundant shells, marine skeletal remains, and shell fragments is called coquina.
When there is directed pressure on a rock what type of metamorphism may occur?
dynamic
Why is it desirable to use more than one fossil in a rock unit to determine its relative age?
Using one fossil can be unreliable because the fossils in an area may have been mixed together, even though they were from different eras. A second fossil gives a more accurate picture.
Does geolgic have to do with a type of rock may contain fossils?
No, geolgic is not a word in English

In what type of rock do most fossils appear?
Rarely a fossil may appear in metamorphic or igneous rock, but the vast majority of fossil evidence presents itself in sedimentary rock. Remains or evidences of life are often preserved by being covered in sediments before decaying or being consumed by predators. The sediments may turn to rock through the process of lithification over time, leaving a record of their presence.Limestone - by far
Is fossil fuel hydrogen?
All fossil fuels contain complex hydrocarbon chains comprised of hydrogen, carbon and oxygen. They also may contain nitrogen, sulfur, moisture, and noncombustible minerals.
Definition of pseudo fossil?
A structure in a rock that appears to be a fossil. Iron an manganese dendrites are an example (see film "Nuts in May").

It will become misshapen or its constituent minerals may realign, recrystallize or form new minerals. In any event, the most likely occurrence is that the fossil will no longer be recognizable.
Which New York State index fossil may have been present in a rock layer that is missing due to the unconformity?
The trilobite is the index fossil
Can a sea shell have an animal print on it?
No. If you have found a hard rock with an animal print on it, it may be a fossil.
Is thin cavity in a rock showing where a shell had decayed a fossil?
Not necessarily. It may be just a fracture.
The combustion of fossil fuels causes the acidity of rain to increase because?
When there is a combustion of fossil fuels acid rain occurs from sulfuric, carbonic, and nitric acid. Fossil fuels may contain radioactive materials.
Do astroids contain ice?
Yes. While they are mostly made of rock or metal, they may contain some ice.
