Fossils are the remains and traces ( such as footprints or other marks) of ancient plant and animal life that are more than 10,000 years old. They range in size from microscopic structures to dinosaur skeletons and complete bodies of enormous animals. Skeletons of extinct species of humans are also considered fossils.
An environment favorable to the growth and later preservation of organisms is required for the occurrence of fossils. Two conditions are almost always present: (1) The possession of hard parts, either internal or external, such as bones, teeth, skulls, shells, and wood; these parts remain after the rest of the organism has decayed. Organisms that lack hard parts, such as worms and jellyfish, have left few geologic records. (2) Quick burial of the dead organism, so that protection is afforded against weathering, bacterial action, etc.
Nature provides many situations in which the remains of animals and plants are protected against
A. in a deep lake.
B. covered by sediment.
C. protected by oil.
D. buried slowly.
