Fossils, Remnants of Our Living World
Deep beneath your own backyard may lie the remains of previous forms of life that are nonexistent in today's world! Discover some of the fascinating facts surrounding these remnants of our living world. Fossils provide great insight to the forms of life that once inhabited our vast planet. Fossils are the actual remains of ancient life! They aid scientists in tracing ancient geographical features such as coastlines, or in establishing the climates of the past. Some of the more common fossils that may be found are ancient clamshells, bone fragments, petrified wood, and leaf prints.
Fossils are created in different ways. Some are preserved through heat. In moist areas, fossils were formed as the original matter was replaced cell by cell with minerals, thus fossilizing or petrifying the once-living matter. Another type of fossil is termed as a stone core. An example is a deceased snail's shell that became filled with sand. Over time, the sand turned into stone, replicating the inner shape of the shell. Some fossils are formed when the body of an animal was buried, then as the insides decayed, the hollow mold was filled with mineral matter, creating a cast of the animal's form. A fossil may simply be a print of a previous form of life, preserved beneath layers of sand or silt over time. There are even fake fossils, called pseudofossils, which are mineral forms that look like fossils. Going on a fossil hunt can be an exciting adventure! Take along a hammer, some protective eye gear, a canteen of water, and a chisel. If you happen to come across something worthwhile, work very carefully to remove your find. Good sources for fossils include areas by water and cutouts as found along highways. But whether you are a fossil finder, or just an admirer, most will admit that fossils are nuggets of fascinating wonder, remnants of our living world… Click Here to Return to American Outback |
