Question

The fossils in this group were collected from limestone and shale rocks. based on what you have learned about the formation of these rock types, what type of environment did these organisms live in?

Answer 1

Answer: Limestone and shale are the two sedimentary rocks that contains numerous fossils.

When the rocks at different places undergoes weathering and erosion, the particles or sediments are transported by the agents such as air, water and ice, and gets deposited at a different place, thereby undergoing compaction and lithification forms the sedimentary rocks.

Fossils are found only in sedimentary rocks and these fossils are found to exist in a shallow and deep marine environment, in which the organisms were able to construct shells of calcium carbonate, which is their hard parts that does not alter.

Answer 2

the type of environment that the Organisms lived in is usually in shallow sea or the sea floor.
Both of them are deposited in deep marine environment and accumulated by floating organisms
