## Appearance

The Fossilized Crinoid is typically a grey, brown, or white rocky specimen featuring stacked, disc-like segments often resembling tiny beads or stars. Some fossils preserve delicate, feather-like arms, showcasing its ancient flower-like form, distinct from spiral ammonites or branching corals.

## Taxonomy

- **Kingdom:** Animalia

## Interesting facts

- Amazingly, these "sea lilies" trapped food using feathery arms!
- Entire mountains in the past were sometimes made from countless crinoid fossils!
- Fossils show some crinoids could crawl around on the ancient seabed!
- Some ancient crinoid "stems" look like strings of star-shaped beads!

## Special abilities

- **Ancient Time Capsule:** Fossilized Crinoid can preserve ancient sea life because its hard parts were replaced by minerals over millions of years.
- **Rock Record Keeper:** Fossilized Crinoid has a unique column of disc-like segments that helps scientists understand ancient ocean environments.
- **Feathered Feeding Clue:** Fossilized Crinoid can show delicate arm imprints that reveal how these 'sea lilies' captured tiny food from the water.

## Measurements & details

- **Length:** 0.01-1 m
- **Era:** Paleozoic-Mesozoic
- **Extinct Millions Years Ago:** 252

## Diet & Feeding

These ancient animals were filter-feeders, catching tiny bits of food floating in the sea!

- **Primary Foods:** Plankton, Detritus, Small organic particles
- **Foraging Method:** Filter feeding

## Ecological connections

- **Eats:** Early Shark (*Cladoselache newberryi*) — Preyed on ancient marine invertebrates including crinoids.
- **Eats:** Ancient Starfish (*Palaeostoma mirabile*) — Known to consume crinoids on the seafloor in ancient oceans.
- **Symbiotic with:** Lace Bryozoan (*Fenestella retiformis*) — Grew attached to crinoid stems for elevated filter-feeding.
