fossils are small living organisms that existed millions of years ago. They mostly have a shell which is the fossil that you can sea. Sedimentary rock is formed when lots of small particles and pieces of rock and often dead organisms, (the fossils) drift down to the sea bed and over millions of years get compressed together to form the rock. The fossil that you see was once a living shelled organism which dies and was preserved as the sedimentary rock formed
Siltstone is a sedimentary rock. It forms on river beds when silt compressed together.
Sedimentary rock is formed when sediments are cemented together due to heat and/or pressure.

Yes,!! Chalk is fine grains of limestone compressed together and limestone is sedimentary, so chalk has to sedimentary.

Sedimentary rocks are formed by the compaction from overlying sediments and by the cementation resulting from the replacement of fluids with minerals, in a process of rock formation known as lithification.

Sandstone is a sedimentary rock which is made up of sand grains which have been compressed to form a rock that has very weak bonds holding the grains together. The grains themselves can be igneous, sedimentary or metamorphic depending on which rock the grains were eroded from.
