Why Are Trace Fossils More Common Than Body Fossils? Trace fossils are formed in place and can therefore tell us about the ancient environment in which the animal lived. One single animal can make thousands and thousands of traces in its lifetime, but it will only leave behind one body when it dies. Because of

How Do Dead Organisms Become Fossil Fuels? A fossil fuel is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, containing organic molecules originating in ancient photosynthesis that release energy in combustion. What are the 4 factors that affect the formation of fossil fuels? Fossil fuels are compound mixtures made
How Do Fossils Form Layer By Layer? Fossil layers are fossils that formed in sedimentary rock. … When, over a long time, layers and layers of sediments get deposited on top of each other, the weight of the top layers presses down on the bottom layers, forming them into rock called sedimentary rock. How are
Why Fossil Evidence Is Consistent With The Scientific Theory Of Evolution? This supports Darwin’s theory of evolution, which states that simple life forms gradually evolved into more complex ones. Evidence for early forms of life comes from fossils. By studying fossils, scientists can learn how much (or how little) organisms have changed as life developed
How Are Mold Fossils Preserved? Casts and molds – A cast or a mold fossil is an impression of a living organism. They are made when an organism dissolves in the Earth and leaves a hollow mold behind. The mold is then filled in by minerals leaving something like a statue of the organism behind.
Why Was There A Gap Of 70 Million Years In The Coelacanth’s Fossil Record? Why was there a gap of 70 million years in the coelacanth’s fossil record? A: Coelacanths became extinct 70 million years ago, and then re-evolved. … C: The fossils must be out there, they just haven’t been found yet. When did
Why Are Transitional Fossils Important In Understanding Evolution? Transitional fossils are remnants of an organism that came in between a known version of a species and the current species. Allegedly, transitional fossils would be evidence for evolution Why are transitional fossils important? Transitional fossils help scientists bridge gaps in the tree of life, resulting in
Are Molds Body Fossils? Body fossils include molds and casts. A mold is the imprint left by the shell on the rock that surrounded it. … Molds of the underside of shell may be left on the surface of rock that formed when sand or mud filled the inside of the shell. These are called
