Detailed explanation-1: -Aquatic animals are more likely to be preserved than terrestrial animals because water ecosystems have greater preservation potential. Preservation potential increases in aquatic environments, low oxygen environments and locations with high sedimentation rates.

Detailed explanation-2: -Organisms with hard parts (bones, shells) have a good chance of fossilization while soft-bodied organisms are rarely fossilized. The enamel and dentin of teeth are harder than bone and as a result, teeth are more likely to be fossilized than other parts of a vertebrate.

Detailed explanation-3: -These marine organisms are an interesting contrast to the Paleozoic marine fossils of the Inland Basin and are evidence of the significant changes in sea life over the last several hundred million years. The most common fossils include mollusks (clams, snails and cephalopods), corals, barnacles, and sharks’ teeth.

Detailed explanation-4: -Updated On: 27-06-2022. Yes, aquatic life forms get fossilised in the sediments of the water bodies. Infact there are more aquatic than terrestrial fossil organisms. Such fossils of sea creatures are found in the mountains as opposed to deep sea beds (in sedimentary rocks).
