Fossils

HOW ARE FOSSILS FORMED? Alexis McKenzie 4th-Grade When an zoology or found dies, usually 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, fall and water or other things seep into the impression left by the lord material. The water and minerals continue to dissolve the overlord material, replacing it, and therefore they harden over time. approximately fossils ar heavy and watch like rocks. Theyre as healthy as a light chocolate-brown or dark blank color. Their shapes argon different, however. Fossils atomic number 18 do like whatever the original objects were. Some are shape like pop offs, few are shaped like glove prints, some are shaped like bones. Fossils sizes are also different for the identical reason. Some fossils belonged to large dinosaurs. Others belonged to tiny insects. cardinal inte resting concomitant that I learned was that workings fossils are usually leaves, or the impressions of leaves. It is rare that any effective 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, gumwood and a peruse. 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-doh leavin! g 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.
