Pterosaur Fossils
- O.C. Marsh's Kansas findings in the late 1800s shaped the image of pterosaurs as pterodactyls, specifically pteranodons.
- Pterosaur fossils are rare due to their fragile, hollow bones, which makes understanding them challenging.
Pterosaur Wings
- Best-preserved pterosaur fossils are found in lagoons, indicating sudden death and quick burial.
- Georges Cuvier corrected the misconception of pterosaurs as sea creatures, recognizing their wings, and named them 'wing finger'.
Pterosaur Features
- Pterosaur head crests, possibly exclusive to males, might have served display purposes like antlers.
- Some pterosaurs, like the Teradustro, had unique features like a 'toothbrush' lower jaw for scooping marine life.
