## Appearance

The Fossilized Coral has a stony, often grey or brownish appearance, sometimes with hints of red or yellow from mineral replacement. It distinctly shows preserved internal structures like radiating septa or honeycomb-like patterns, clearly differentiating it from ordinary rocks.

## Taxonomy

- **Kingdom:** Animalia

## Interesting facts

- Scientists use fossil coral to help find hidden oil and gas reserves! Wow!
- Some fossil corals can glow under a special ultraviolet light! Wow!
- The oldest fossil corals are more than 500 million years old! Wow!
- You can find fossil coral on mountains, far from any ocean today! Wow!

## Special abilities

- **Ancient Architect:** Fossilized Coral can be an 'Ancient Architect' because its stony skeletons built massive reefs that shaped prehistoric oceans.
- **Climate Archivist:** Fossilized Coral has 'Climate Archivist' rings that reveal ancient ocean temperatures and conditions to scientists.
- **Petrified Puzzle:** Fossilized Coral can be a 'Petrified Puzzle' because studying its internal structures helps us understand evolution.

## Measurements & details

- **Era:** Paleozoic to Mesozoic Eras
- **Extinct Millions Years Ago:** 252

## Diet & Feeding

Tiny polyps filter-fed microscopic plankton from the ancient seas.

- **Primary Foods:** Zooplankton, Phytoplankton, Marine detritus
- **Foraging Method:** Filter feeding

## Ecological connections

- **Shelter:** [Trilobite](https://www.snappit.app/explore/trilobite) (*Phacops rana*) — Provided protected nooks within ancient reef structures.
- **Shelter:** Spinose Brachiopod (*Mucrospirifer mucronatus*) — Its hard structure provided substrate for attachment in ancient reefs.
- **Depends on:** Ancient Shark (*Ctenacanthus amblyx*) — Used the diverse reef ecosystem as a hunting ground and habitat.
- **Shelter:** Orthoceras (*Orthoceras regulare*) — Ancient coral reefs provided diverse habitats for these marine predators.
