Question

Factors favourable for preservation of fossil

Answer 1

This is sort of a best-case scenario for rapid burial. A plant or animal that is buried in mud, silt or other protective substances very shortly after death is much more likely to be preserved as a fossil. Some of our fossilized dinosaurs were originally covered in sand, soil or dense foliage shortly after they died. Some ancient creatures were even preserved in a pit of tar! Rapid burial contributed to their being preserved as fossils because it protected them from the destructive forces of a terrestrial ecosystem.
