Microfossils
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
Microfossils are tiny fossilized remains of microorganisms, typically less than a millimeter in size. They include remnants of bacteria, algae, plankton, and other microscopic life forms preserved in rocks and sediments. Microfossils are crucial for understanding Earth's geological history, climate changes, and evolution of early life on the planet.
