Which statement about fossils is false?

Which statement about fossils is false?

Land organisms are more likely to become fossils than marine organisms.

Complete preservation is possible if an organism is buried in

any of the above (tar, mud, and tree sap)

Petrified wood forms because of

permineralization

Fossils can provide clues about

all of the above (Past Climates, Plate Tectonics, and Extinct Species)

Compression is most common for fossils of

leaves

a. permineralization Is ---

Mineral deposit make fossil

Cast Is a fossil have a ---------------

imprint fills in with minerals

Fossilization Is a process of --------------------

Petrified Fossil

Mold is another form of --------

Cavity fossil

Amber Is a --------------------

tree resin

Earth history is _________________ billion year old

4.6 Billion

The geologic time scale based on major events that describe changes in ---

all of them (Climate, Geography and Atmosphere, and Life)

The great first explosion of life recorded in fossil record occurred in the period

Cambrian

In the geologic time scale the largest unit of time are ----

Eons

The________________ Eon spans the most recent 544 million years .

Phanerozoic

what part of the animal are most likely to fossilized

All (Shell, Teeth, and Bones)

The _________ was an era dominated by the dinosaurs

Mesozoic

How does an eon differ from an era?

Eons measure the time during which humanity existed, while eras measure everything since the Earth was formed.

The Mesozoic Era was the Age of Dinosaurs, and the current Cenozoic Era is the Age of _____.

Mammals

Identify whether or not the following would be uniformitarianism or catastrophism:

Deposition

Examples of imprint fossils made by compression are

fossil leaves

Fossilized insects have been found preserved in amber which is hardened

tree sap

In petrified wood, the original wood has been slowly replaced by

minerals

Scientists who study fossils are

Palaeontologists

The body of an animal is more likely to become fossilized if it:

is buried deeply in the ground

The unaltered remains of fossilized animals include

mummified and frozen mammoths

Which of the following could be a fossil?

all of the above (a woman who lived 15,000 years ago found frozen in a glacier, a penguin that lived 100,000 years ago found mummified in a dry valley in Antarctica, and a wasp inside a 30 million year old block of amber)

Most of the mammal fossil record consists of

teeth

If a wood fragment that is buried in sediment has minerals deposited in its empty spaces, the process of fossilization is called

permineralization

The presence of marine fossils on the top of Mt. Everest indicates

sea level was once higher than the top of Mt. Everest.

Which of the following parts of organisms are most likely to be fossilized?

Shells

Preserved traces of organisms might include

molds

Preserved remains that have become fossils have turned to

rock

Which type of organism’s remains are least likely to be preserved as fossils?

jellyfish

Fossils can show us

All of the above (how extinct organisms looked, what past environments were like, and what geological processes occurred in the past.)

To be used as index fossils, fossils must represent an organism that

lived over a wide area.
