28 lut 2024 · A fossil is the preserved remains, impression, or trace of any once-living organism from a past geological age. These include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.
15 paź 2024 · Fossils are the preserved remains, or traces of remains, of ancient organisms. A fossil can preserve an entire organism, just part, or traces of one (for example, footprints). Bones, shells, fur, skin, footprints, feathers and leaves can all become fossils. Fossils can be very large or very small.
Fossils introduces students to different types of fossils and explains how they form. Students will learn related vocabulary and understand the world of a paleontologist. They will discover how these special rocks help scientists explain the way life was for extinct animals.
Summary: Petrified fossils result from permineralization, the replacement of once-living matter by minerals. Solutions containing silicates, carbonates, iron or other minerals seep into the gaps and spaces between the cells, first encasing the cells and eventually replacing the cells themselves.
There are two types of fossils, body fossils and trace fossils. Body fossils are plant and animal remains like leaves, teeth, shells and bones. Trace fossils are evidence left behind by animals, things like footprints, burrows and even poo! Trace fossils usually form as moulds or casts. A mould.
Fossils are pieces of dead animals and plants and children often think that only dinosaurs make fossils. By modelling and discussing fossil formation in various ways, children will understand how fossils are formed.
