Pteranodon longiceps

Overview

Pteranodon is probably the most famous pterosaur of all time—and one of the most recognizable prehistoric creatures! Living approximately 86-84 million years ago during the Late Cretaceous, this magnificent flying reptile soared over the Western Interior Seaway of North America with its iconic long crest and impressive wingspan. Despite often being called a "pterodactyl," Pteranodon was actually a very specialized fish-hunter.

Taxonomy & Classification

• Order: Pterosauria
• Family: Pteranodontidae
• Diet: Piscivorous (fish-eater)
• Type: Advanced pterosaur

Remember: Pteranodon was NOT a dinosaur—it was a flying reptile that lived alongside dinosaurs!

Physical Characteristics

Size & Build

• Wingspan: 5.6-7 meters (18-23 feet)—males were larger!
• Body Length: About 1.8 meters (6 feet)
• Weight: About 25-50 kg (55-110 lbs)
• Crest Length: Up to 1 meter (3 feet) in males!

The Iconic Crest

Pteranodon's most famous feature:

• Long, backward-pointing crest on the skull
• Males had much larger crests than females
• Probably used for display and mate attraction
• May have helped with flight stability (like a rudder)
• Different species had different crest shapes

Toothless Beak

• No teeth—the name "Pteranodon" means "wing without tooth"
• Long, pointed beak like a pelican
• Perfect for scooping up fish
• Lightweight skull for efficient flying

Master of the Skies

Built for Soaring

Pteranodon was an incredible flyer:

• Long, narrow wings for efficient soaring
• Could glide for hours without flapping
• Used thermals (rising warm air) to stay aloft
• Probably flew hundreds of kilometers to find fish
• One of the best gliders ever to evolve

Flight Style

• Similar to modern albatrosses
• Minimal energy needed to stay airborne
• Cruised at speeds up to 40 km/h (25 mph)
• Could stay airborne for days at a time

Fishing for a Living

Ocean Hunter

Pteranodon was a dedicated fish-eater:

• Flew over the Western Interior Seaway
• Scooped fish from the surface (like a pelican)
• May have dive-bombed to catch fish
• The beak had a throat pouch for storing fish
• Ate small fish whole

Diet

• Fish of various species
• Squid and other cephalopods
• Whatever it could catch and swallow
• Fed chicks by bringing fish back to nests

Sexual Dimorphism

Males vs. Females

Pteranodon showed big differences between sexes:

Feature	Males	Females
Wingspan	7m+	3.5m
Crest	Very large	Small
Pelvis	Narrow	Wide (for eggs)

The size difference was dramatic—males were twice as big!

Living Over the Sea

The Western Interior Seaway

Pteranodon lived in a unique world:

• A shallow sea split North America in two!
• Stretched from the Gulf of Mexico to the Arctic
• Full of fish, sharks, and marine reptiles
• No land for hundreds of miles
• Perfect for an ocean-going pterosaur

Ecosystem Neighbors

Shared skies and seas with:

• Mosasaurs—giant marine reptiles
• Hesperornis—a diving bird
• Giant sharks and fish
• Other pterosaurs (but Pteranodon was biggest)

---

Nesting & Breeding

Coastal Colonies

Pteranodon probably:

• Nested in large colonies on cliffs
• Like modern seabirds
• Males displayed their large crests to females
• Laid eggs in simple nests
• Both parents may have fed the chicks

Discovery & Fame

First Giant Pterosaur

• First discovered in the 1870s in Kansas, USA
• Named by Othniel Charles Marsh in 1876
• One of the first pterosaurs found in America
• Thousands of specimens now known
• One of the most studied pterosaurs

Not a "Pterodactyl"!

Common Mistake

People often call any pterosaur a "pterodactyl," but:

• "Pterodactyl" technically refers to a different group
• Pteranodon was a pteranodontid, not a pterodactyloid
• The two groups lived at different times
• Pteranodon was much larger than true pterodactyls
• Scientists use specific names for specific pterosaurs!

---

Cool Facts

• Pteranodon means "toothless wing"—fitting for its beak!
• Male Pteranodon were twice the size of females
• The crest could be longer than the skull in some males
• It could fly for days without landing
• Over 1,200 specimens have been found—making it one of the best-known pterosaurs
• Pteranodon often appears in movies as a generic "pterodactyl"
• Kansas (now landlocked!) was once covered by ocean where Pteranodon flew

Pteranodon was the ocean wanderer of the Cretaceous—a crested, toothless giant that soared over ancient seas and became the world's most famous pterosaur!
