Question

paleontologists have found an area rich in ammonite fossils. although erosion over millions of years has altered the topography of the ocean floor, they have recreated a chronological history of the ammonite fossils. based on the paleontologists data, which numbered fossil was been found in the lowest layer of sediment? a 4 b 7 c 8 d 12

Explanation:

In sedimentary rock layers, older fossils are typically found in lower layers. Among the numbered fossils, we need to identify the one at the greatest depth which represents the lowest sediment layer. By observing the depth - scale on the left of the diagram, fossil 7 is at the greatest depth.

Answer:

B. 7
