What are 3 things fossils can tell us about that organism?

A fossil provides evidence about the approximate size of an organism, its living location, and the conditions that an organism lived in. A fossil can tell us

the color of an organism, its favorite food, and the age of the organism

.

What does the fossil record determine?

The Fossil Record

Scientists date and categorize fossils to determine

when the organisms lived relative to each other

. The resulting fossil record tells the story of the past and shows the evolution of forms over millions of years.

How can the fossil record be used to find out how an animal walked?

For example, fossils of wastes from ancient animals provide evidence of what the animals ate. Dinosaur tracks can give evidence about how many legs a dinosaur walked on, how fast it moved, and when it lived. … In other words, the fossil record shows that

life on Earth changed over time

.

What four things do fossil records show?


Rock Layers and the Age of Fossils

The fossils and the order in which fossils appear is called the fossil record. The fossil record provides evidence for when organisms lived on Earth, how species evolved, and how some species have gone extinct.

What do fossils tell us about plants and animals?

Fossils are

the remains or traces of ancient life that are usually buried in rocks

. Examples include bones, teeth, shells, leaf impressions, nests, and footprints. This evidence reveals what our planet was like long ago. Fossils also show how animals changed over time and how they are related to one another.

What can fossils tell us about past climates?

Fossils that provide indirect (proxy) information on past environmental conditions are called

paleo-indicators

. … The presence of fossils representative of these organisms can tell us a great deal about the environments of the past; what the climate was like, and what sorts of plants and animals inhabited the landscape.

What is an example of fossil record?

Examples include

bones, shells, exoskeletons

, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

What can fossil teeth tell us about extinct animals?

By looking at the teeth of extinct animals,

scientists are able to determine their diet

. When fossils with long pointed teeth are found, scientists know that the animal was a carnivore (animals that eat meat). If a fossil with flat, smooth teeth is found, the animal is likely a herbivore (animals that eat plants).

What is a fossil record quizlet?

fossil record. information

about past life

, including the structure of organisms, what they ate, what ate them, in what environment they lived, and the order in which they lived. extinct. no longer existing or living.

How does comparing a fossil to existing animals help the scientists better understand the ancient animal?

Fossils allow these scientists to determine the features of extinct species.

Paleontologists

compare the features of species from different periods in history. … Through studying fossils, we now know that today's organisms look much different in many cases than those that were alive in the past.

How can fossils show relationships between extinct and living creatures?

Fossils document the existence of now-extinct species, showing

that different organisms have lived on Earth during different periods of the planet's history

. They can also help scientists reconstruct the evolutionary histories of present-day species.

What do fossils reveal about the evolution of a horse?

The fossil record reveals how horses evolved. … Later fossils show that horses changed as well. They became taller, which would help them see predators while they fed in tall grasses. They

evolved a single large toe that eventually became a hoof

.

How does the fossil record of animals compare to animals that exist today?

Animals in the fossil record

are the same as animals that exist today

. Animals in the fossil record are ancestors of animals that exist today. Animals in the fossil record have no similarities to animals that exist today. Animals in the fossil record are more complex than animals that exist today.

What information can be derived about Antarctica having fossil of ancient plants and animals?

What information can be derived about Antarctica having fossils of ancient plants and animals?

Antarctica drifted to the Southern hemisphere because of the melting of glaciers that traps the plants and animals

. Antarctica has a very nice climate that caused these organisms to migrate and stay.

How are fossils different from animals living today?

Fossils provide

evidence about life

on Earth. They tell us that life on Earth has changed over time. Fossils in younger rocks look like animals and plants that are living today. Fossils in older rocks are less like living organisms.

Does the fossil record tell us the whole story?

The fossil record certainly has

gaps

, mostly because the conditions required to create fossils have been rare ever since life began on Earth. A very small percentage of animals that have lived and died ever became fossils. … And new fossils continue to reveal transitional forms that some said don't exist.

How would you describe a fossil?

Fossils are

the preserved remains, or traces of remains, of ancient organisms

. Fossils are not the remains of the organism itself! They are rocks. A fossil can preserve an entire organism or just part of one.

Does the fossil record tell us the whole story about evolution?

Fossils provide solid evidence that organisms from the past are not the same as those found today; fossils show a progression of evolution. … The resulting fossil record

tells the story of the past

and shows the evolution of form over millions of years.

Is the presence of animal fossils tells that South America Africa and Antarctica were once connected?

Many scientists thought that Africa, India, Australia, South America, and Antarctica had once been connected into a large ancient continent known as

Gondwana

. … Those fossils belonged to a species previously found in Africa, providing further evidence that the distant present-day continents were once connected.

How are fossils in the fossil record classified?

The interpretation of the fossil record requires describing fossils,

classifying them to place them in a biological context, and determining their age to give them chronological context

. Fossil classification follows the same system of taxonomy as modern biology. Fossil organisms are placed in a genus, species, etc.

What fossils tell us for kids?

Fossils are the remains of living things, which have been preserved, and many are millions of years old. They are very important because they show the process of evolution, which is how living things have changed over time. Fossils also tell us

about plants and animals that may no longer exist

.

What might fossilized poop tell us about an animal's activity?


A coprolite

like this can give scientists clues about an animal's diet. By looking at the shape and size of coprolites, as well as where they were found, scientists can work out what kind of animal the droppings might have come from. Coprolites can also contain clues about an animal's diet.

How do we know what extinct animals looked like?

Scientist know extinct animals

appearance by the fossils they have found

. They use these fossil bones, plus much knowledge of anatomy, to draw pictures of the animals . They know what their bodies looked like through the bones, and their color patterns through provided mommefied feathers, fur, skin etc…

Why is the fossil record important?

The fossil record

helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era

. Therefore, some discovered fossils are able to be dated according to the strata, a distinct layer of rock, that they are found in. …

What can fossils tell us about the past quizlet?

What do fossils tell us? Fossils give clues about

organisms that lived long ago

. They help to show that evolution has occurred. … when hard parts of an organism are buried in sediment such as sand, silt, or clay.

What animal did horses evolve from?

Equus—the genus to which all modern equines, including horses, asses, and zebras, belong—evolved from

Pliohippus

some 4 million to 4.5 million years ago during the Pliocene.

What is the strongest evidence for evolution?

Comparing DNA

Today, scientists can compare their DNA.

Similar DNA sequences

are the strongest evidence for evolution from a common ancestor.

Why are fossils considered to be an incomplete record of evolution?

Why are fossils considered to be an incomplete record of evolution? The fossil record is

biased for organisms that had hard shells and skeletons

. … Endosymbiosis is an evolutionary theory that explains the origin of eukaryotes and suggests a specific order in which this might have occurred.

What types of changes are recorded in the fossil record?

The collection of fossils and their placement in chronological order is known as the fossil record. It documents

the existence, diversity, extinction, and change of many life forms and environmental changes

throughout the history of life on Earth.

Are there any animal alive today that are like the pterosaurs?

Pterosaurs were the first vertebrate creatures to evolve powered flight and conquer the air—long before birds took wing. … Unlike dinosaurs, which are survived today by birds, pterosaurs

left behind no living descendants

.

Do fossils provide a complete record of all the extinct species that lived on Earth Why or why not?


No

, it takes a lot to become a fossil and only 2% of living things ever become fossils. Earth has had several mass extinctions throughout its long history.

What does the fossil record indicate about plants and animals that lived on the Earth in the past?

The fossil record shows

that life on Earth has evolved, or changed over time

. Simple one-celled organisms have given rise to complex plants and animals. The fossil record show that organisms have evoloved and many have become extinct. living things die and are buried by sediment.

What fossils provide evidence that over time animals moved from living in the water to living on dry land?


Transitional fossils

are fossils that provide evidence organisms may have transitioned from water to land. An example of this is the Tiktaalik fossil. It has fins and gills like a fish, but it also has leg bones and lungs like a land mammal.

Why extinct plants and animals were not fossilized?

Organisms decompose more quickly when they are in contact with oxygen. Most environments exposed to the open air are in contact with plenty of oxygen, so the soft tissues of dead organisms, whether plants or animals, decay quickly. … For an organism to become a fossil,

it must not decompose or be eaten
