. features that are shared by more than one species The fossil species were probably related to each other. … the extinction of many fossil species at the same time The extinction of many would indicate a mass extinction caused.
Can fossils have marks?
A fossil is physical evidence of a prehistoric plant or animal. This may be their preserved remains or other traces, such as marks they made in the ground while they were alive. … Dinosaur trace fossils include footprints, imprints of their skin or feathers, and poo – called coprolites.
What do fossil shells tell us?
Tiny shells give huge insights
But they are so well preserved that they reveal
new details of their body shape and early life stages
. These details show that some species thought to be extinct had actually survived the extinction, and others originated tens of millions of years earlier than previously believed.
What does growth rings in fossil trees or shells tell us?
Growth rings tell us
the number of years that individual lived
.
What does the fossil record refer to?
The fossil record helps
paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era
. It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
What are the 4 types of fossils?
Four Types of Fossils Sort Packet
A sort activity using the four types of fossils (
mold, cast, trace, and true form
).
What is the oldest fossil answer?
The oldest known fossils, in fact, are
cyanobacteria from Archaean rocks of western Australia
, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old! Cyanobacteria are among the easiest microfossils to recognize.
Is a rock 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. … Bones, shells, feathers, and leaves can all become fossils.
Why are fossils so important?
As pieces of once living things, body fossils are
evidence of what was living where and when
. Trace fossils are valuable because they “animate” the ancient animals or plants by recording a moment of an organism's life when it was still alive.

How is the fossil record important to evolution?
Fossils are important evidence for evolution
because they show that life on earth was once different from life found on earth today
. … Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms.
What fossil animals show growth rings as well?
Some fossil animals show growth rings as well. The growth rings in these
fossil oyster shells
tell us how old the animals were when they died.
What do fossils provide?
Fossils also
show how animals changed over time and how they are related to one another
. Fossils can't tell us everything. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of their behavior. Fossils are very rare.
What are examples 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.
How far back does the fossil record go?
The new analysis aside, fossils of the earliest multicellular organisms had been dated to 565 million to 543 million years ago. In recent years, some evidence pushed the date of the earliest animal fossil as far back as
575 million years
.
What are three important limitations to the fossil record?
The fossil records suffer from 3 types of bias:
temporal bias, geographic bias and taxonomic bias
. Fossil of certain geologic time may be easier to find as compared to those or other era, such as newer fossils are easier to find than older ones.
