Fossils: Molds and Casts Quiz

The preserved remains or traces of ancient living organisms found in sedimentary rocks.

Traces left behind by ancient organisms that show their activities, like footprints or burrows.

The preserved parts of an ancient organism's body, like bones, teeth, or shells.

A fossil formed when a complete organism is quickly buried in a preserving environment, like snow or amber.

A type of complete body fossil where an organism gets trapped in hardened tree resin, preserving its entire form.

The solidified resinous matter secreted by pine trees during ancient geologic eras.

The study of fossils, which helps us understand life on Earth in the past.

Fossils are classified by how they were formed (preserved).

A type of fossil where the remains of an organism are preserved in hardened tree resin.

A replica of the internal shape of an organism's structure, often left behind in sedimentary rocks.

The process of creating a replica of an object's shape by filling a mold with a material like plaster.

The hollow space inside a mold that represents the internal details of an organism.

The process of preserving the body of an organism by preventing decomposition, often through burial in amber or other materials.

The process by which the soft parts of an organism decompose, leaving only the hard parts like bones or shells.

Rocks formed from layers of sediment that accumulate over time.

A type of sedimentary rock often formed from the fossilized remains of tiny marine organisms.

A replica of the external details of an old living organism left after its death in sedimentary rocks.

The process of converting organic matter to rock by replacing it with minerals, part by part.

Fossils where minerals have replaced the original organic matter, preserving the shape and structure.

Fossils formed by the replacement of wood with minerals, showcasing the anatomy of ancient trees.

Traces left by activities of ancient organisms, showing their behaviors in sedimentary rocks.

A fossilized dinosaur tooth, egg, or piece of wood.

Fossils that existed in a specific time period and are found in multiple locations.

Fossils formed by the replacement of the original organic material with minerals.

Conditions required for fossils to form: hard skeleton, rapid burial, preserving medium like sediment.

The study of fossils to understand past life and Earth's history.

Fossils showing a transition between two different types of organisms.

Fossils that lived for a short period and widely distributed geographically, used to determine the age of sedimentary rocks.

Fossils provide information about the past environment, indicating climate and the types of organisms that lived there.

A sequence of fossils found in sedimentary rocks, revealing the evolution of life from simple to complex organisms.

Fossils found in El-Mokattam mountain indicate that the area was once a sea floor over 35 million years ago.

The study of fossils reveals the evolution of life starting in the sea and then establishing on land, with organisms becoming increasingly complex.

Fossils of ferns indicate that the environment they lived in was a hot and rainy tropical environment.

Fossils of corals indicate that the environment they lived in was a clear warm shallow sea.

Fossils are crucial for petroleum exploration, as they help geologists identify the types of rocks that might contain oil and gas.
