Chapter 11 Review pt.3

An overwhelming majority of fossils are

• dinosaurs.

• missing links.

• marine (ocean) organisms.

• vertebrates.

Petrified wood forms by a process called

• casting.

• compression.

• permineralization.

• replacement.

Which of these, if fossilized, would be considered microfossils?

• animal droppings

• exoskeletons

• plant spores

• all of these

Fossils that seem to appear reliably in the proper geologic sequence and that are used by secular geologists to determine the age of rock strata are called

• index fossils.

• missing links.

• intermediate species.

• polystrate fossils.

What remarkable discovery came from the examination of a thigh bone of a 68-million-year-old Tyrannosaurus rex fossil in 2005?

• DNA

• prehistoric bacteria

• soft tissues

• stone arrowhead

What is the name for the study of fossils?

• archaeology

• paleology

• paleontology

• petrology

Who developed the system used today to classify organisms?

• Darwin

• Linnaeus

• Lyell

• none of these

Fossils showing organisms that are in the process of evolving from one form to another are known as

• index fossils.

• microfossils.

• transitional forms.

• none of these.

When the population of a species begins to shrink due to having more deaths than births in a generation, it is possibly headed toward

• extinction.

• fossilization.

• succession.

• superposition.

All the following statements would be acceptable to a young-earth paleontologist except which one?

• A. Most fossil-bearing sedimentary rocks came from the Flood.

• B. Volcanic eruptions probably accompanied the Flood and released ash.

• C. Birds were killed and buried later in the Flood event than amphibians were.

• D. Fossils found in the same layer came from organisms from the same habitat.
