Stimulus


A student finds a Gogi Sparillis fossil in Millard, Utah. The student wonders what kind of environment the Gogi organism experienced when it existed.


Figure 1 - Gogi Sparillis Fossil

Reading 1 - Utah Fossils

Fossils are the remains or traces of living organisms. These remains have been preserved by natural processes over time. Fossils range from spectacular skeletons to tiny sea shells.

Many fossils of ancient life have been found in Utah. There is a wide variety of information we can gather from studying the fossils that have been found here. These remains give us clues to how life might have been like millions of years ago.

One such fossil is of the Gogia spiralis. Gogia are an extinct species of marine organisms. They lived attached to the sea floor. The spiral arms, seen in the image, were used to collect food from the sea water as it moved past.

One such fossil is of the Gogia spiralis. Gogia are an extinct species of marine (ocean) organisms. They lived attached to the sea floor. The spiral arms, seen in the image, were used to collect food from the sea water as it moved past.

Rock forms layers with the oldest materials on the bottom and youngest on top.
Rock forms layers with the oldest materials on the bottom and youngest on top.

Both fossils are found in the same layer so they existed at the same time and would be the same age.

1 answer

Question 1: Based on the information from Reading 1, what type of environment did the Gogi organisms live in?

  • Response: Marine

Question 2: Choose the paragraph that has the evidence to support your answer for Question 1.

  • Response: One such fossil is of the Gogia spiralis. Gogia are an extinct species of marine (ocean) organisms. They lived attached to the sea floor. The spiral arms, seen in the image, were used to collect food from the sea water as it moved past.

Question 3: The Gogi fossil was found in the same rock layer as a Paradoxides fossil. Based on the information in Figure 2, during which time period did this organism exist?

  • Response: Cambrian

Question 4: Based on the information in Figure 2, approximately how old is the Gogi fossil?

  • Response: 100 million years old

Question 5: Which sentence below best explains how comparing the Gogi fossil to the Paradoxides fossil helps us determine the age of the Gogi fossil?

  • Response: Both fossils are found in the same layer so they existed at the same time and would be the same age.

Question 6: Fill in the blank with the correct answer.

  • Response: Utah was experiencing a marine environment during the time period when the Gogi organisms existed.

Question 7: Choose two statements below that support your claim:

  • Response:
    1. Both fossils are found in the same layer rock.
    2. Both of the fossils are of sea-dwelling creatures that needed water to survive.

Question 8: Do you have enough evidence to support your claim? Do you think you need to have more evidence? Why or why not?

  • Response: Yes, I believe I have enough evidence to support my claim. The fossils of both Gogi and Paradoxides being found in the same layer indicates they lived during the same geological period, and their nature as marine organisms strongly suggests that Utah was a marine environment during that time. This connection between the fossils provides a clear illustration of the ancient environment.

Question 9: The evidence that was collected is sufficient to support the claim because it confirms that both Gogi and Paradoxides were marine organisms found in the same geological layer, indicating a marine environment in Utah during their existence.
