Fossils are most commonly found within sedimentary rocks due to the favourable conditions of burial and limited alteration through time. Sedimentary rocks form on the Earths surface as sediment accumulates in rivers, lakes and on the seafloor in particular.

Where are fossils most commonly found?

sedimentary rocks Fossils are mostly found where sedimentary rocks of the right age – which for dinosaurs is the Mesozoic – are exposed. The best places are river valleys, cliffs and hillsides, and human-made exposures such as quarries and road cuttings.

In which type of rocks can fossils be found?

sedimentary rocks Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

Are fossils common or rare?

Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals.
