Sedimentary rock is the only type of rock that will contain fossils, but there are several types of sedimentary rock.
Examples:
Clastic Sedimentary Rocks (particles of silt and/or sand that cement together): Conglomerate, Breccia, Sandstone, Siltstone, Shale.
Examples:
Chemical Sedimentary Rocks (forms when mineral constituents become supersaturated and inorganically precipitate):
Evaporates:
Halite, Gypsum
Carbonates:
Limestone, Fossiliferous Limestone
Siliceous Rocks: Chert
Organic Sedimentary Rocks: Coal.
The rocks listed in BOLD will likely be found with fossils.
usually sand/mud traps something, then hardens to become a rock.
Sedimentary rocks will most likely contain a fossil because it is a very soft and crumbly type of rock. Hope this helps.

Coelophysis would mostly be found in the New York lowlands.
A preserved fossil is an organism or Animal that has been PERFECTLY PRESERVED for lots of years, or however old it may be. For example, a wooly mammoth frozen in the ice for millions of years would be known as a preserved fossil.There are 2 different types of fossil preservation- preservation with alteration and without. With alteration also has different types. The type of organism you are looking for depends on the how it was preserved.
The desert was once covered by water.
The insect fossil would be examined for revelations about it's physical attributes and compared to other identified fossil and living insets. If the insect is unknown, it would be classified as a new species.
the level of oxygen dissolved in the water.
Limestone and shale contain fossils.
Limestone
A fossil would most likely be found in sedimentary rocks
Sandstone. Sandstone is a sedimentary rock - which is the only type of rock which can contain fossils.
Most likely not.
in your bed
Probably, carbonateous fossil.

Yes, many types of insects and spiders have been found trapped in fossilized tree resin, (amber), including cockroaches.
Sedimentary.
The time frame does change the fossil world wide. The fossil in today's present would be different then it would be years ago.
