If you just walk to a formation and pick out a fossil without filling out the right paperwork and being absolutely certain of where you are, you are probably breaking the law not to mention the fact that trained paleontologists are much better qualified at properly documenting and excavating fossil sites.
But let's assume that, regardless of how it was acquired, you have what you think is a piece of fossil bone. Out of its geologic context it is impossible to compare it to the surrounding rock fossils are often different in color and smoother than rocks from the same deposit , but if there is a break on the specimen you may be able to check its internal structure.
A rock or concretion, like the one I showed to my professor, will be solid, and the inside of the rock will look like the outside. Fossil bone, on the other hand, will probably preserve the internal bone structure. In a fossil bone you will be able to see the different canals and webbed structure of the bone, sure signs that the object was of biological origin. You can even try a tongue test. The porous nature of some fossil bones will cause it to slightly stick to your tongue if you lick it, though you might want to have a glass of water handy if you feel compelled to try this.
By following these guidelines it becomes easier to determine whether or not you have really found a fossil bone. It does not take a Ph. Oil and Natural Gas. Carbon Sequestration. General Information.

They became extinct at the end of the Cretaceous Period at roughly the same time as the dinosaurs disappeared. Ammonites were marine animals and had a coiled external shell similar to the modern pearly nautilus.
Fossil White Cephalopods. Cephalopods have a very long history of life on Earth at least million years. They were particularly abundant during the Palaeozoic Era to million years ago , and are often the most common fossils in rock of that age.
Bivalves have inhabited the Earth for over million years. They first appeared in the Middle Cambrian, about million years before the dinosaurs. They flourished in the Mesozoic and Cainozoic eras, and abound in modern seas and oceans; their shells litter beaches across the globe. Because many crinoids resemble flowers, with their cluster of waving arms atop a long stem, they are sometimes called sea lilies. But crinoids are not plants. Like their relatives—starfishes, sea urchins, sea cucumbers, and brittle stars—crinoids are echinoderms, animals with rough, spiny surfaces and a special kind of radial symmetry based on five or multiples of five.
Information can be gathered from sources such as fossilized bones, footprints, stomach stones, feces, internal organs, soft tissues, eggs and feathers. The eggs are over 60cm 2ft long and 20cm 8in wide.
Ancient Mollusk, The Orthoceras. The name means straight horn, referring to the characteristic long, straight, conical shell. The preserved shell is all that remains of this ancestor of our modern-day squid. Corals are simple animals that secrete skeletons made of calcium carbonate. They are close relatives of sea anemones and jellyfish and are the main reef builders in modern oceans.
Corals can be either colonial or solitary. As fossils, corals are found worldwide in sedimentary rocks. Based on these fossils, we know that the corals began their long evolutionary history in the Middle Cambrian, over million years ago. In Kansas, they are fairly common in Pennsylvanian and Permian rocks, deposited from about to million years ago. A shark tooth is one of the numerous teeth of a shark.
Sharks continually shed their teeth; some sharks shed approximately 35, teeth in a lifetime, as well as replace them by producing thousands of more. There are four basic types of shark teeth: dense flattened, needle-like, pointed lower with triangular upper, and non-functional. Wanna know what else is a fossil? Coprolites are the petrified remains of animal dung. What is a fossil? What am I hunting for?
How in the world did a once living organism become a fossil? Below is a great diagram I got off the internet that clearly explains what a fossil is. Specifically, how a dinosuar fossil forms:. Another graphical example below explains what a fossil is very clearly as well.
The animal dies and fall to bottom of ocean. It is covered very quickly with sand and mud to protect it from scavengers. Most of the body parts except the skeleton are eaten by bacteria and have dissloved away. Lot of layers of sand and dirt pile up on top of the skeleton. Water is rich is minerals and the skeleton soaks up the water. The minerals attach itslef to the bone and relplace the actual bone. Erosion and uplift eventually brings the fossil to the surface where it can be found.

Beautiful Minerals. HOw Fossils Form. Fossils are formed in a number of different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt.
Ammonites Their widely-known fossils show a ribbed spiral-form shell, in the end compartment of which lived the tentacled animal. Gastropods Or univalves , are the largest and most successful class of molluscs.
