Which sediment type is most likely to form fossil-rich limestone?
Quick Answer
Marine carbonate sediment is most likely to form fossil-rich limestone, especially in shallow warm seas.
The Full Story
Carbonate sediment deposited in shallow marine environments often becomes fossil-rich limestone. Shell fragments, coral debris, and other calcium carbonate materials accumulate on sea floors and are compacted over time. Because many marine organisms have calcium carbonate skeletons, limestone can preserve abundant fossils. Such rocks are important for studying ancient environments and the history of life.
Key Facts
1.Forms in shallow marine settings
2.Rich in calcium carbonate and fossils
3.Limestone often preserves shells and corals
