Practice questions

Evidence from four layers in one area (oldest to youngest):
  1. Volcanic ash layer; few fossils.
  2. Dark shale with fish fossils; indicators suggest low-oxygen water.
  3. Light-colored limestone with many shell fossils; indicators suggest clearer, shallow water.
  4. Sandstone with dinosaur footprints; indicators suggest dry land surface.
Based on the pattern, if a NEW youngest layer formed after Layer 4 and indicators suggested the area became a shallow sea again, what change in fossils would be most likely?
