The majority of the time fossils are dated using relative dating techniques. Using relative dating the fossil is compared to something for which an age is already known. For example if you have a fossil trilobite and it was found in the Wheeler Formation.
How do you tell if a rock has a fossil in it?
Mostly, however, heavy and lightly colored objects are rocks, like flint. Paleontologists also examine the surfaces of potential fossils. If they are smooth and do not have any real texture, they are probably rocks. Even if it is shaped like a bone, if it does not have the right texture then it is probably a rock.
How is a trilobite fossil formed?
Fossil formation is revealed by erosion. Wind, rain, freeze and thaw, even earthquakes will help force the trilobite out of its burial ground and out into the light. If he or she is lucky enough, the trilobite will reveal itself in time to be spotted by a rock-hounder or fossil-digger.

Wait for the eggs around the hermaphrodites’ and female’s legs to disappear. This means the eggs were fertilized and the mother attached the egg to something in the tank or dropped them in the substrate. Depending on her size, the triops will produce between 15-60 eggs per brood.
