Fossils are here today because way before humans were living on land there were dinosaurs first and some people still see the fossils today from when the dinosaurs used to be here but now dinosaurs are enstinct .
They say that there were more animals before that went extinct, but the animals that are here today survived and are still here.
Antarctica does have dinosaur fossils! Dinos used to live there before the climate changed.
There are fossils of tropical plants there.
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.
Alive today - no. As fossils and mummified remains - yes.
in science
Alive today - no. As fossils and mummified remains - yes.
Fossils are classified into three. Here is the fossil type and example(s): cast fossils (filled in with molds), trace fossils (burrows, gastroliths, footprints), and true form fossils (real animal or real animal part).
today's species evolved from those of the past.
Aside from fossils we can learn about organisms and how they have changed over the years by looking at the plants and animals we have today.
Tirtiary
Fossils showing animals of the past display some similarity to animals of today as well as some differences. When we start at the bottom of the fossil record (where all the oldest fossils are) and work our way up through all the rock layers of the different ages in geologic time, we start to notice the changes in the fossils and how they lead up to the animals of today
