GEOLOGY

Detailed explanation-1: -Have an eye for detail Look for regular lines, marks or patterns on pebbles, like the ridges or growth lines of a shell. Look for tiny pieces among the beach pebbles, not just big stones. Often crinoid stems or belemnites can be as small as your little fingernail.

Detailed explanation-2: -Fossils are mostly found where sedimentary rocks of the right age are exposed, such as river valleys, cliffs and hillsides, and human-made exposures such as quarries and road cuttings.

Detailed explanation-3: -Giant, sunken pieces of an ancient continent from the time of the dinosaurs may have been discovered deep in the Indian Ocean, scientists say.

Detailed explanation-4: -The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.
