Pteranodon Standing Beside a Prehistoric Nest

This page illustrates a pteranodon positioned on the edge of a cliff. Beside the flying reptile sits a stone nest filled with fossilized dinosaur eggs.

Nesting Habits of Prehistoric Flying Reptiles

Pteranodons were not dinosaurs but flying reptiles that lived during the Late Cretaceous period. Fossil evidence suggests they nested on high coastal cliffs to keep their eggs safe from terrestrial predators and to take advantage of ocean wind currents for launching into flight.

Real Colors of Pteranodons and Cliff Formations

  • Pteranodon head crest: Dull orange or dark red

Questions and Answers About Pteranodons and Fossil Eggs

How large was the wingspan of a full-grown Pteranodon?
Adult Pteranodons had wingspans reaching up to twenty feet across, allowing them to glide vast distances over ancient oceans.
Were Pteranodon eggs soft or hard-shelled?
Fossil discoveries indicate that pterosaur eggs had soft, leathery shells similar to modern reptile eggs, requiring moist nesting conditions.
How did pteranodons launch themselves into flight from cliffs?
They used a quadrupedal launch, vaulting off four limbs using their strong arm bones to generate immediate upward momentum.
