CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Permineralization. The most common method of fossilization is permineralization. After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.

Detailed explanation-2: -Trace Fossils Trace fossils are marks left by an animal or plant that has made an impression. These fossils include nests, burrows, footprints or any other markings of the animal’s time on the earth.

Detailed explanation-3: -Impression fossils form when the organisms original bone or tissue is removed by processes that occur after burial, such as ground water flow. If the organisms remains are decomposed entirely, leaving an empty space in the shape of the organism, it is referred to as a cast.

Detailed explanation-4: -Trace fossils (sometimes also called ichnofossils) provide evidence about the movements and/or activities of ancient organisms, but not necessarily about their appearance.

Detailed explanation-5: -Body Fossils and Trace Fossils The fossils of bones, teeth, and shells are called body fossils. Most dinosaur fossils are collections of body fossils. Trace fossils are rocks that have preserved evidence of biological activity. They are not fossilized remains, just the traces of organisms.
