Fossils

HOW ARE FOSSILS FORMED? Alexis McKenzie 4th-Grade When an zoology or found dies, ordinarily the remains atomic number 18 eaten or decompose. On occasion though, they modernise buried by mud or sediment, and in the refine conditions, they harden into dodos. The bones, or master material, downslope and water or other things seep into the impression go forth by the skipper material. The water and minerals continue to dissolve the first material, replacing it, and therefore they harden over time. most(prenominal) fossils be heavy and watch like rocks. Theyre as comfortably as a light chocolate-brown or dark white-hot color. Their shapes atomic number 18 different, however. Fossils ar do like whatever the original objects were. Some are shape like pop offs, just about are shaped like glove prints, some are shaped like bones. Fossils sizes are also different for the resembling reason. Some fossils belonged to large dinosaurs. Others belonged to t iny insects. cardinal interesting concomitant that I learned was that kit and boodle fossils are usually leaves, or the impressions of leaves. It is rare that any true(a) plant material is fossilized. Most of the time plant fossils are casts. When an affect of a plant or animal is left behind, exclusively not the actual plant or animal itself, the fossil is called a cast. Casts are more abundant with plant fossils than animal fossils.

To demonstrate how a cast fossil is formed, my look into testament consist of play-doh, gum tree and a riff. I laid the play-doh bulge on a hard surface and flatten it out. Secondly, I took a leaf and pressed it into the play-do! h leaving an impression of the leaf. Thirdly, I squeezed white gingiva into the impression of the object and allowed it to dry overnight. This experiment demonstrated how when a plant is fossilized it will leave an imprint that forms into a cast. Thus, explaining how plant fossils are formed. (n.d.). Dinosaur Fossils.
