in rock layers, jellyfish fossils are found lower than trilobite fossils, and trilobite fossils are found lower than ammonite fossils. what can be determined from this information? trilobites existed before jellyfish and ammonites. jellyfish existed before trilobites and ammonites. ammonites existed before trilobites and jellyfish. jellyfish, trilobites, and ammonites lived together.
Answer
Answer:
B. Jellyfish existed before trilobites and ammonites.
Explanation:
Step1: Understand fossil - layer principle
In general, older fossils are found in lower rock layers.
Step2: Analyze given fossil - layer information
Jellyfish fossils are lower than trilobite fossils, so jellyfish are older than trilobites. Trilobite fossils are lower than ammonite fossils, so trilobites are older than ammonites.
Step3: Determine the correct answer
Based on the above, jellyfish existed before trilobites and ammonites.
