Can you compare a femur of a dinosaur that was on Earth 68 mya with an animal today?

No, because dinosaur bones are not preserved

No, because we do not know what a femur is

No, because animals today do not have femurs

Rapid burial helps a fossil by:

protecting it from decay and scavengers

#2. Gentle burial preserves what?

The delicate parts and details of the organism.

The color of the surrounding rocks.

The movement of tectonic plates.

Why do burrowing animals have a high preservation potential?

The animals are already buried before they die.

They have harder shells than other animals.

They live in colder environments.

They are larger than other animals.

What kind of information does this burrow cast give scientists about the deep past?

Animal behavior and interactions

The chemical composition of the atmosphere

The migration patterns of birds

Where would an animal be buried if the conditions were Anoxic “without oxygen”?

In very deep water where there is little to no oxygen

On a mountain peak exposed to air

In a dry desert with plenty of sunlight

In a forest with abundant plant life

Do you think there are soft-bodied creatures that lived in the past that we have no record of?

Only hard-bodied creatures existed

We have records of all past creatures

What occurs in this step?

An animal is buried by sediment shortly after it dies.

The animal is eaten by scavengers.

The animal turns into a living fossil.

The animal is immediately fossilized.

Movement of tectonic plates lifts up the sediments and pushes the fossil closer to the surface.

tectonic plates, sediments, closer

Erosion from rain, rivers, and wind uncovers fossils how?

wears away the remaining rock layers

How do people expose fossils?

people digging for fossils will expose the preserved remains.

people painting rocks will expose the preserved remains.

people watering plants will expose the preserved remains.

people flying kites will expose the preserved remains.

How does the mineralized water get to the dead organism?

seeps through the layers of sediment

is carried by wind to the organism

is produced by the organism itself

is created by the decaying process

How does a mold fossil form?

hard parts of an organism are buried in sediment

The process of cast formation occurs when water with dissolved minerals and sediment

fills the mold’s empty spaces

evaporates quickly from the surface

breaks down the original organism

In the end what makes the cast fossil?

Minerals and sediment that are left in the mold

What does the thin layer of carbon left behind from an organism show?

delicate parts, like leaves on a plant

the amount of water in the soil

List 3 other examples of trace fossils.

Burrows, eggshells, nests, tooth marks, gizzard stones, poop

Amber, petrified wood, bones, shells

Dinosaur skeletons, leaves, tree trunks, coral reefs

Pearls, diamonds, gold nuggets, silver coins

What are some examples of unaltered fossilization?

Imprint, carbon film, permineralization

Can we pull genetic material from fossilized animals?

No, it is impossible to extract any material
