  1. I agree, sediment layer


  2. Fossils are typically found in sedimentary rock, almost all of which were originally deposited as sediments by moving water. Subsequent processes hardened them into sedimentary rock, as overlying pressure squeezed the water out and the grains were cemented together. Often plants and animals were trapped, being buried in the sediments. As the sediments hardened into sedimentary rock, the dead things hardened into fossils.  

  3. under the sediment layer.

  4. The only thing I would add to the above good answers is that there can be many sedimentary layers at various levels, representing various past sedimentary periods.  

    I thought you might get the impression it was just one layer.  Sorry if I am being too obvious.

  5. precambrien to very recent (before 5,000 yrs) because they take long time to form... at least last ice age (10,000 yrs)

  6. Fossils are found in a sedimentary layer.

  7. Fossils can be found in any sedimentary rock as old as or younger than the age of the earliest organisms preservable on Earth.  That's pretty much a pure vanilla answer, however.

    Abundant fossils are found in sedimentary rocks formed in the marine environment and which are younger than about 600 million years of age (that is, younger than the earliest Cambrian rocks).  They are found less abundantly in non-marine rocks (because environments that will preserve the remains or traces of plants and animals are harder to come by).
