They are mostly found in Sedimentary Rocks
Sedimentary
A fossil is evidence of an organisms existence, not a type of rock. Most fossils are found in sedimentary rocks.
fossils are fine in metamorphic rock
Relative dating. Paleostratigraphy correlates layers of rock using index fossils found within them.
Tertiary fossils are usually found in sedimentary rock layers. Sedimentary rocks are formed by the accumulation and compression of sediments over time, making them a common host for preserving fossils from the Tertiary period.
Sedimentary Rock.
Fossils are nearly always found in some type of sedimentary rock. Limestone is a sedimentary rock which very commonly contains fossils, as is coal.

Tertiary fossils are usually found in sedimentary rock layers. Sedimentary rocks are formed by the accumulation and compression of sediments over time, making them a common host for preserving fossils from the Tertiary period.
Fossils that are the most useful for correlation tend to be found in various types of rocks, are widespread, and easy to recognize. One rock type where fossils are found is sedimentary rocks.
