Shale

Probably the most common fossil preserving rock; contain fossils that are perfectly preserved. They can contain vertebrates, invertebrates, or plants.

Limestones

Also a very fossiliferous rock, these represent both shallow and deep tropical seas. Can find Invertebrate fossils, as well as remains of armored fish and shark teeth in it

Coal/Coal Shales

Plants, fish, insects, marine invertebrates, and even dinosaur footprints

Identify coquina

Looks like chewed up oatmeal.

Identify Diatomite

Similar to chalk limestone, but less chalky and lighter.

Identify Dolostone

Usually a very light shade of pink.

Identify sandstone

Grainy and it does not have to be layered, though it commonly is.

Identify limestone

Looks and feels like chalk.

Fossiliferous Limestone

Has fossils that are relatively small, but does not have to be covered with fossils.
