a section of a rock layer is shown. the evidence in these rock layers best supports which conclusion? the oldest fossils in this section of rock are trilobites. eurypterids are related to modern - day scorpions and crabs. eurypterids were the least common type of organism in this section of rock. there is some overlap in the presence of brachiopods and ammonites on earth. key: ammonites, brachiopoda, eurypterida, trilobites
Answer
Brief Explanation:
In rock - layer analysis, the principle of superposition states that in undisturbed rock layers, the oldest layers are at the bottom. Trilobite fossils are found in the bottom - most layer shown. This indicates that the oldest fossils in this section of rock are trilobites. The other statements cannot be supported by the given rock - layer evidence. There is no information about the relationship of eurypterids to modern - day scorpions and crabs, the relative commonness of eurypterids compared to other organisms, or the overlap of brachiopods and ammonites in terms of their presence on Earth from just this rock - layer section.
Answer:
The oldest fossils in this section of rock are trilobites.
