## Appearance

The Plesiosaur Vertebra is typically light brown to dark grey, often smooth but sometimes porous, with a distinct, hourglass-like central body. It has projecting processes where muscles and ribs attached, and its fossilized texture might show crystal growth.

## Taxonomy

- **Kingdom:** Animalia

## Interesting facts

- Plesiosaurs had four giant flippers, like an underwater turtle!
- Some plesiosaurs had necks longer than their entire body!
- Their fossil remains are found on every continent, even Antarctica!
- They swallowed stones, maybe to help them dive or digest food!

## Special abilities

- **Ancient Blueprint:** Plesiosaur Vertebra can reveal the animal's size and how it moved because its unique shape and connection points guide reconstruction.
- **Deep-Sea Sturdiness:** Plesiosaur Vertebra has strong, dense bone that helped the creature withstand immense water pressure, letting it dive deep.
- **Flipper Anchor:** Plesiosaur Vertebra provided strong attachment points for powerful muscles, giving the animal its incredible flipper-driven propulsion.
- **Fossil Timekeeper:** Plesiosaur Vertebra can show growth lines, much like tree rings, revealing how old the plesiosaur was when it died.

## Measurements & details

- **Length:** 3-17 m
- **Weight:** 450-10000 kg
- **Era:** Mesozoic
- **Extinct Millions Years Ago:** 66

## Diet & Feeding

Ancient ocean hunters, plesiosaurs ate various marine life with their sharp teeth.

- **Primary Foods:** fish, squid, belemnites, ammonites
- **Foraging Method:** Pursuit

## Ecological connections

- **Hunts:** Hybodus shark (*Hybodus delabechei*) — Larger plesiosaurs preyed on ancient sharks like Hybodus.
- **Eats:** Dapedium fish (*Dapedium politum*) — Many smaller fish species were a staple food for plesiosaurs.
- **Eaten by:** Liopleurodon (*Liopleurodon ferox*) — Smaller plesiosaurs were sometimes prey for giant pliosaurs.
