## Appearance

The Fossilized Algae often appears as layered, dome-shaped, or wavy rock structures, typically grey, brown, or reddish-ochre. Its distinctive concentric patterns and fine laminations differentiate it from other sedimentary rocks, showcasing ancient microbial mats.

## Taxonomy

- **Kingdom:** Animalia

## Interesting facts

- Ancient algae completely changed Earth’s air, filling it with oxygen!
- Some fossilized algae look like giant, bumpy layered pancakes!
- These fossils are some of the oldest signs of life on Earth!
- They helped create the first huge structures ever built by living things!

## Special abilities

- **Oxygen Producer:** Fossilized Algae has the ability to produce oxygen because its living ancestors released this vital gas, transforming Earth's early atmosphere.
- **Rock Builder:** Fossilized Algae can build layered rock formations like stromatolites, because ancient algal mats trapped sediment, gradually growing and solidifying over millennia.
- **Time Capsule:** Fossilized Algae has the ability to act as a time capsule because its preserved layers offer scientists clues about Earth's earliest environments and life.

## Measurements & details

- **Length:** 0.1-5 m
- **Weight:** 50-10000 kg
- **Era:** Precambrian

## Diet & Feeding

Ancient algae made their own food using sunlight, carbon dioxide, and water through photosynthesis.

## Ecological connections

- **Eaten by:** Kimberella (*Kimberella quadrata*) — grazed on ancient microbial mats
- **Eaten by:** Dickinsonia (*Dickinsonia costata*) — absorbed nutrients from microbial mats
- **Eaten by:** Spriggina (*Spriggina floundersi*) — possibly grazed on ancient algal mats
