nearly all fossils are found in sedimentary rock & if something is found in something else, then that something else contains that something ->  sedimentary rocks can contain fossils  sedimentary rocks can contain fossils & metamorphic rocks do not contain fossils ->  sedimentary rocks can contain fossils and metamorphic rocks do not contain fossils  sedimentary rocks can contain fossils and metamorphic rocks do not contain fossils & sedimentary rock can be changed into metamorphic rock ->  if a sedimentary rock with fossils is changed into metamorphic rock , then the fossils will likely be destroyed  metamorphic is a class of rock & sedimentary is a class of rock ->  sedimentary and metamorphic are different classes of rock  sedimentary and metamorphic are different classes of rock & formation in the rock cycle means an old class of rocks changes into a new class of rocks ->  the rock cycle can change sedimentary rock into metamorphic rock  if a sedimentary rock with fossils is changed into metamorphic rock , then the fossils will likely be destroyed & the rock cycle can change sedimentary rock into metamorphic rock -> fossils are likely to be destroyed in the rock cycle
