Sandstone.
Sandstone is a sedimentary rock - which is the only type of rock which can contain fossils.
Sandstone is the rock type most likely to contain fossils, as it is formed from compacted grains of sand that can preserve the shapes of organisms. Granite, marble, and basalt are less likely to contain fossils, as they are formed through processes that typically do not preserve organic remains.
A fossil would most likely be found in sedimentary rocks
You would be more likely to pull out a white marble as there are no red marbles in the bag.
in your bed
Most likely not.
"Most likely" means "most favorable." If there was a bag of marbles with 6 blue marbles and 1 red marble, it would be most likely that you would draw a blue marble rather than a red, because there are more of them.
Probably, carbonateous fossil.

MOSQUITOS
shale and sandstone
Soft, porous stones like limestone or sandstone are more likely to show the greatest amount of weathering due to their susceptibility to erosion by water, wind, and other environmental factors. Harder stones like granite or marble are more resistant to weathering.
A fossil will most likely be found in a sedimentary rock because sedimentary rocks are made out of organic fragments such as rocks, shells, leaves, fossils, pebbles, and so on. A metamorphic rock would not hold a fossil because a metamorphic rock forms under great heat and pressure, and fossils would be destroyed under such conditions. An igneous rock would not hold a fossil because they form through the hardening of molten rock and fossils would be burned up and cremated in lava. Thus, fossils will most likely be found in a sedimentary rock.
