Understanding Fossil Formation by Replacement
Oct 17, 2024
Fossil Formation through Replacement
Key Process
Initial Burial
: An organism is buried under sediment.
Water Seepage
: Water seeps through the sediment.
This water helps dissolve some of the hard parts of the organism.
Mineral Replacement
Mineral Carriage
: Minerals carried by water replace the parts of the organism that get dissolved.
Resulting Fossil
: The process leaves behind a fossil composed of minerals.
These minerals replace the original parts of the organism.
Outcome
The final fossil is a mineralized version of the original organism, showcasing the structure while not retaining the original organic material.
