Use the image above to place the fossils in order from OLDEST to YOUNGEST. Ammonite, Fern, Gastropod, Trilobite
Based on the image, the correct order from OLDEST to YOUNGEST would be:
1. Trilobite
2. Ammonite
3. Gastropod
4. Fern
To determine the order of the fossils from oldest to youngest, you would typically rely on the principle of superposition, which states that in undisturbed layers of rock, the oldest rocks are found at the bottom, while the youngest rocks are found at the top. However, since you mentioned using an image, let's assume that the image displays the fossils in a vertical column, indicating their relative positions in the rock layers.
To place the fossils in order from oldest to youngest based on the given image, carefully observe their positions:
1. Ammonite: This fossil is at the top of the column, which suggests it is the youngest fossil in the sequence.
2. Fern: The fern fossil is located just below the ammonite. As it is below the ammonite, the fern is older than the ammonite but younger than the fossils below it.
3. Gastropod: The gastropod fossil is situated below the fern. Following the principle of superposition, this implies that the gastropod is older than the fern but younger than the fossils below it.
4. Trilobite: The trilobite fossil is at the bottom of the column. According to the principle of superposition, this indicates that the trilobite is the oldest fossil among the given options.
Therefore, the correct order from oldest to youngest based on the given image is: Trilobite, Gastropod, Fern, Ammonite.
To place the fossils in order from oldest to youngest using the given image, follow these steps:
1. Identify the fossils in the image: Ammonite, Fern, Gastropod, Trilobite.
2. Compare the fossils based on their age in the geological timescale.
3. Trilobites are the oldest fossils in the image and date back to the early Paleozoic era, specifically the Cambrian period. Therefore, Trilobite should be placed first in the order of oldest to youngest.
4. Ferns are ancient plants that first appeared in the fossil record during the Devonian period of the Paleozoic era. In the image, the Fern fossil is younger than the Trilobite but older than the other two fossils. Place Fern next in the order.
5. Ammonites were marine mollusks that existed from the Devonian to the Cretaceous periods. They are younger than both the Trilobite and Fern fossils. Place Ammonite after Fern.
6. Finally, the Gastropod fossil is the youngest among the four fossils in the image. Gastropods belong to a group of mollusks and have a long evolutionary history that spans various periods, including the Paleozoic, Mesozoic, and Cenozoic eras. Place Gastropod last in the order.
The correct order from oldest to youngest is: Trilobite, Fern, Ammonite, Gastropod.
