Detailed explanation-1: -A paleontologist collects as many fossils as possible from a rock or sediment. Once the fossils are prepared by scraping and cleaning, they are sorted by geometry. Fossils with very similar geometry are assumed to belong to a single species.
Detailed explanation-2: -Fossils are the remains or traces of ancient life that have been preserved by natural processes, from spectacular skeletons to tiny seashells. Imprints, tracks and trails can also become fossilised, like dinosaur footprints or worm burrows. These are called trace fossils.
Detailed explanation-3: -Fossils provide important evidence for evolution and the adaptation of plants and animals to their environments. Fossil evidence provides a record of how creatures evolved and how this process can be represented by a ‘tree of life’, showing that all species are related to each other.
Detailed explanation-4: -Which is a way that paleontologists have contributed to humans’ understanding of the history of life? They grouped organisms by the period in which they existed.
