Fossil Homework

This is a starfish fossil. Fossils are preserved remains or traces of animals, plants or organism's from the past. This fossil is A Mold or Cast. It is because the original remains dissolved and the mud or sediment seeped in and made a mold.





This is a mammoth fossil. It is a Original Remain because it was frozen and it is almost completely intact. They are preserved in its entirety.
