When we think of fossils, our mind goes to rocks that have impressions of items in them. These items can include things like a leaf or a bone, that were embedded over time, that left a grooved impression in the stone.
But the word fossil means "having been dug up" in Latin (fossus is the Latin word for fossil). That definition opens up the fossil world, doesn't it?
So, dinosaur bones are fossils. So is amber. Finding a nice piece of amber with a mosquito or other insect inside is a treasure! And petrified wood is a fossil.
Fossils with impressions can be found in limestone, coal, and other rocks. The impressions can be made from shells, leaves, skeletons, teeth, and more.
A fossil kit and book will help kids learn what geological period each fossil was made as well as identification of many fossils.
For young children, using fossil rubbing plates to make their own fossil drawings is a great way to introduce them to fossils. The rubbing plates have raised images of leaves and dinosaur bones that let kids place paper over top to create their very own fossils!
