Sedimentary Rocks and Fossilization

These flashcards cover key vocabulary and concepts related to sedimentary rocks, fossilization processes, and environments where fossils may be found.

Sedimentary Rock

A type of rock that is formed by the accumulation of sediment, which may include fossils.

Fossilization

The process by which organic material is preserved in sediments and transformed into fossils.

Permineralization

A type of fossilization where mineral deposits form internal casts of organisms.

Replacement

A fossilization process where the original material of an organism is replaced by minerals.

Plastic Deformation

A taphonomic effect where fossilized bones are distorted by pressure without breaking.

Marine Sedimentary Environment

An area in the ocean where sediments accumulate, often preserving marine fossils.

Long Bone Alignment

The orientation of long bones in the same direction due to water flow during deposition.

Coal

A type of sedimentary rock formed from the remains of decomposed plants, often found in swampy areas.

Sandstone

A sedimentary rock made up of sand-sized particles, typically found in rivers and beaches.

Mudstone or Shale

Sedimentary rocks formed from mud or silt deposits, often found in lake environments.
