Fossils can be very large or very small. Microfossils are only visible with a microscope. Bacteria and pollen are microfossils. Macrofossils can be several meters long and weigh several tons. Macrofossils can be petrified trees or dinosaur bones.

The fossils of bones, teeth, and shells are called body fossils. Most dinosaur fossils are collections of body fossils. Two million years ago, the first known Pokémon™® walked the earth. Scientists thought many were extinct like the dinosaurs because only fossils had been found—until now. A remote island has been discovered in the south seas, an island where the Pokémon fossils have come to life! Preserved remains become fossils if they reach an age of about 10,000 years. Fossils can come from the Archaeaean Eon (which began almost four billion years ago) all the way up to the Holocene Epoch (which continues today). The fossilized teeth of wooly mammoths are some of our most "recent" fossils. Some of the oldest fossils are those of ancient algae that lived in the ocean more than three billion years ago. Paleontologists are people who study fossils. Paleontologists find and study fossils all over the world, in almost every environment, from the hot desert to the humid jungle. Studying fossils helps them learn about when and how different species lived millions of years ago. Sometimes, fossils tell scientists how Earth has changed. Over time, minerals in the sediment seep into the remains. The remains become fossilized. Fossilization usually occur in organisms with hard, bony body parts, such as skeletons, teeth, or shells. Soft-bodied organisms, such as worms, are rarely fossilized.A fossil can preserve an entire organism or just part of one. Bones, shells, feathers, and leaves can all become fossils.
