## Appearance

The Fossilized Sponge is typically a grey or tan rock formation, showing porous textures and often a cup or vase-like shape. Tiny, sharp spicules, which were its skeletal elements, may be visible under magnification, making it distinct from plain rock.

## Taxonomy

- **Kingdom:** Animalia

## Interesting facts

- Fossils show some ancient sponges grew over a meter tall!
- Some fossil sponges helped build ancient reefs alongside early corals.
- The oldest known fossil sponges are over 600 million years old!
- Tiny glass-like spicules are often perfectly preserved in fossil sponges.

## Special abilities

- **Time Capsule:** Fossilized Sponges have structures preserved that help scientists understand ancient ocean life and environments.
- **Structural Builder:** Ancient sponges helped create reef-like structures, providing shelter and habitat for other early ocean creatures.
- **Filter Master (Ancient):** The fossil represents a living sponge's ability to filter huge amounts of water for food, cleaning ancient seas.

## Measurements & details

- **Length:** 0.01-0.5 m
- **Weight:** 0.01-1 kg
- **Era:** Paleozoic
- **Extinct Millions Years Ago:** 450

## Diet & Feeding

Ancient sponges filter-fed tiny particles like plankton and bacteria from the water.

- **Primary Foods:** Plankton, Bacteria, Detritus
- **Foraging Method:** Filter feeding

## Ecological connections

- **Symbiotic with:** Archaeocyathid (*Archaeocyathus atlantica*) — co-built ancient reefs alongside early sponges, creating habitat.
- **Symbiotic with:** Cloudina (*Cloudina carinata*) — formed ancient reef structures with early sponges in the Ediacaran period.
