Habitats are changing and some animals cannot adapt, putting them at risk of becoming endangered when only a few remain or extinct when their entire kind has died off. Scientists learn about past animals and plants like dinosaurs by finding fossils in different locations around the world, as fossils provide information about ancient lifeforms and their historic habitats.
