Fosillada iyo isbeddelka noocyada waqtiga

Fossils provide evidence about organisms from long ago and their habitats. All fossils are the mineralised remains of once-living organisms or of traces left behind by organisms. Fossils show that some species have gone extinct. Fossils show that the features of some species have changed over time. There are limitations to the conclusions and explanations that can be made from fossil evidence.
