Fossil Record
The diagram below shows the fossil record of
different species.
The diagram below shows the fossil record of
different species.
Part 1) List the time period that each fossil species
first appears in.
When did a major extinction event most likely
occur?
U:
X:
V:
Y:
W:
Z:
Part 2) Which species is the only one that hasn’t
gone extinct according to the chart?
3.
Part 3) According to the chart which species has
lived for the longest amount of time?
Part 4) Can Fossil Z ever be found in a rock layer
that doesn’t contain Fossil X?
According to the records of fossil species V and
W, which statement is most likely true?
A.
Fossil species W appeared before fossil
species V, allowing fossil species W to
survive longer.
B.
Fossil species W was ancestral to fossil
species V because it appeared before fossil
species V.
C.
Fossil species W had greater genetic
variability than fossil species V, allowing
fossil species W to adapt and survive longer.
D. Fossil species W had lower reproductive
success than fossil species V, allowing smaller
populations to adapt and survive.

Fossil Record
In a section of the Grand Canyon, scientists have
found the fossil remains of several different groups
of organisms. The diagram below represents the
number and age of the fossils the scientists found.
The width of each shaded area in the diagram
below indicates the relative number of fossils
found.
Which of the following statements is supported by
the fossil record?
A.
Group C is now extinct.
B.
Group D has been in existence the longest.
C.
Group A is the most recent organism to come
into existence.
D. Group B was the most numerous organism 10
million years ago.
Part 1) At what point in time does group A have
the greatest number of fossils?
Part 2) Which group had the most fossils 10
million years ago?
Part 3) Which group is the youngest?
Part 4) Which group is the oldest?
