Final answer:
To answer the question, fill in the tables on pages 197-201 and analyze the characteristics of the fossils to determine their identities and ages.
Step-by-step explanation:
The question is asking you to fill in tables on pages 197-201 to help answer a series of questions about the identity and age of specific fossils. Specifically, you need to determine the identity and age of the fossils based on the information provided in the reference images.
Make sure to ignore any specimens that are listed as not responsible for in the question. By analyzing the characteristics of the fossils, such as the type of the skeleton, body plan, habitat, and feeding behavior, you can make an educated guess about their identities and ages.
