Sedimentary rocks show fossils, because of pre-existing life forms.
They also show ripple marks due to weathering and erosion...
Sedimentary rocks
Sediment
Most fossils are found in sedimentary rock, which is the most common type of rock on Earth. Sedimentary rocks form when particles of sediment are deposited by water or wind, and then hardened over time.
The Doushantuo rock formation in China encompasses fossils. The fossils within the Doushantuo rock formations have been found to contain organisms that share traits with Amoebas.
Fossils definitely go through the rock cycle. Melting at some future point of time is a possibility, but not a certainty.
Index fossils are the fossils of short-lived species which, because of their short lives, can be used by scientists to identify the age of the rock strata in which they're found. (For example, if you know a certain species only lived in the Cambrian period, and you find some fossils of this species in some rock, then you know the other fossils you find in that rock must also have come from the Cambrian period.) Some examples of species that left behind index fossils, and their related historical periods, are:Billingsella corrugagta - Cambrian period, Palaeozoic eraCactocrinus multibrachiatus - Mississippian period, Palaeozoic eraScaphites hippocrepia - Cretaceous period, Mesozoic eraNeptunea tabulata - Quarternary period, Cenozoic eraSee the links below for more examples and info.

In general, ripple marks are those marks left by water or wind or a surface they have affected. Ripple marks caused by water may appear on rock, or on sand caused by water or wind. Use the link below for more information and some pics.

Fossils are most likely to be found in sedimentary rock.
Sedimentary rock is where we look for fossils.
