A fossil is formed in the same shape as the hard part of the animal, like a tooth or bone.

Do archeologists lick bones?

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 Earth’s surface as sediment accumulates in rivers, lakes and on the seafloor in particular.

Where is the richest source of fossils found?

Sedimentary rocks are the richest source of fossils.

Sedimentary rocks form from layers of sand and silt that are carried by rivers to seas and swamps, where the minerals settle to the bottom along with the remains of organisms. As deposits pile up, they compress older sediments below them into layers called strata.

Why didnt dinosaur bones decompose?

When a dinosaur bone is encased in sedimentary rock, the moisture from the surrounding sediment infuses the bone with these minerals. … After the process is undergone for millions of years, there isn’t really any bone left and the only way for the fossil to “deteriorate” is for it to wear down through erosion.
