Tapejara: The Old Being

If you look up at the sky in the Early Cretaceous of Brazil, you might see something that looks less like a reptile and more like a flying windsurfer. This is Tapejara, one of the most distinctive pterosaurs ever discovered. Its name comes from a Tupi word meaning “The Old Being,” but there was nothing old-fashioned about its design. With a massive, sail-like crest rising from its skull, Tapejara was a masterpiece of aerodynamic evolution.

Discovered in the famous Santana Formation—a fossil paradise that preserves soft tissues like skin and muscle—Tapejara has become an icon of South American paleontology. It wasn’t the biggest flyer, but it was certainly one of the weirdest.

The Crest: A Sail in the Sky

The most defining feature of Tapejara is its crest.

• The Structure: The crest wasn’t just bone. It consisted of a bony ridge at the front of the snout and a bony prong at the back of the head. Between these supports stretched a massive membrane of soft tissue, creating a structure that looked like a ship’s sail or a shark fin.
• Function: Why have a giant sail on your head?
  • Display: The most likely function was for showing off. In life, the crest was probably brightly colored—reds, blues, or yellows—used to attract mates or intimidate rivals.
  • Aerodynamics: Some scientists believe the crest acted like a rudder, allowing Tapejara to make incredibly tight turns. This would have made it highly agile, able to dart through forests or canyons with ease.
  • Thermoregulation: A large surface area full of blood vessels could have helped the animal dump excess heat, keeping it cool in the tropical Brazilian sun.

A Weird Diet for a Flyer

Most pterosaurs, like Pteranodon, were fish-eaters (piscivores). Tapejara was different.

• The Beak: Its beak was short, deep, and downturned, almost like a parrot’s. It had no teeth.
• Frugivory: This shape is perfect for plucking fruits and seeds. Many paleontologists believe Tapejara was one of the first fruit-eating pterosaurs (frugivores). It may have played a crucial role in spreading the seeds of early flowering plants across the continent.
• Omnivory: It likely wasn’t a strict vegetarian. Like a modern toucan or raven, it probably ate whatever it could find—insects, small lizards, carrion, and fish. This flexibility allowed it to thrive in a diverse ecosystem.

Video Game Stardom

Tapejara owes much of its modern fame to the video game Ark: Survival Evolved.

• The Agile Flyer: In the game, Tapejara is prized not for its speed, but for its maneuverability. It is the only flyer that can strafe (move sideways), fly backwards, and latch onto vertical walls. While the wall-latching is speculative, the agility fits with the “rudder-crest” theory.
• Multi-Passenger: It is also famous for having a saddle that holds three players, making it a “tactical helicopter” of the dinosaur world. This depiction has cemented Tapejara as a tactical, skilled flyer in the minds of millions of gamers.

The Santana Ecosystem

Tapejara lived in a vibrant, watery world. The Santana Formation was a large inland sea or lagoon system teeming with life.

• The Giants: It shared the skies with much larger pterosaurs like Tropeognathus (which we will meet later). While Tropeognathus dominated the open water, Tapejara likely stuck closer to the shoreline or the forests.
• The Swimmers: The waters were filled with massive fish like Mawsonia (a coelacanth) and predators like Spinosaurus relatives (Irritator). Tapejara had to be careful when coming down to drink.

Evolution of the Tapejarids

Tapejara gave its name to an entire family of pterosaurs: the Tapejaridae.

• Global Reach: While Tapejara is Brazilian, its relatives have been found in China (Sinopterus) and Europe (Europejara). This shows that the “short-faced, big-crested” body plan was a global success story.
• Extreme Crests: Later members of the family, like Tupandactylus, evolved even crazier crests. Tupandactylus had a crest so large it looked like a sailboat with wings. Tapejara represents the “classic” form from which these extremes evolved.

Conclusion

Tapejara wellnhoferi is a reminder that pterosaurs weren’t just “flying lizards” that skimmed the ocean for fish. They were diverse, complex animals that filled many niches. Some were the seagulls of the Cretaceous, but Tapejara was more like a flying toucan—colorful, loud, and at home in the trees. Its unique silhouette makes it instantly recognizable. Whether hanging off a cliff in a video game or adorning a museum display, the “Old Being” with the mohawk remains one of the most charismatic flyers of all time.

Frequently Asked Questions

Q: Could it walk on land? A: Yes. Pterosaurs were surprisingly good walkers. They walked on all fours (quadrupedal), folding their wings back. Tapejara, with its strong limbs, was likely quite comfortable foraging on the ground.

Q: Did it eat dinosaurs? A: Only tiny ones. A baby dinosaur or a small lizard would have been a tasty snack, but Tapejara wasn’t a big game hunter.

A Cultural Icon

Tapejara has transcended paleontology to become a symbol of Brazilian science. It appears on stamps, in local museums, and even in street art. Its “Old Being” name connects modern Brazil to its indigenous roots, while its fossil connects it to a deep geological past. It is a source of national pride, proving that some of the most amazing animals to ever fly did so over the ancient lakes of Ceará.

Q: How big was it? A: It had a wingspan of about 3.5 meters (11 feet). That sounds big (wider than a car), but for a pterosaur, it’s medium-sized. It was very lightweight, probably weighing only around 35 kg.

A Legacy of Color

Tapejara changed the way we see pterosaurs. Before its discovery, they were often depicted as drab, leathery gliders. The incredible crest of Tapejara forced paleoartists to use color. It opened the door to the idea that the skies of the Cretaceous were filled with brilliant reds, blues, and yellows. Today, when you see a colorful pterosaur in a movie or book, you can thank Tapejara for leading the way. It brought the rainbow to the reptile world.

Q: Why “The Old Being”? A: The name comes from Tupi mythology. It refers to a legendary entity, fitting for a creature that looks like it belongs in a myth rather than scientific reality.

The Mystery of Flight

One of the biggest questions about Tapejara is how its crest affected its flight. Wind tunnel tests suggest that while the crest created drag, it also provided immense stability. It acted like a vertical stabilizer on an aircraft, preventing the animal from yawing (twisting) uncontrollably. This would have been crucial for a creature that spent its life flying through the turbulent air currents of a canyon or forest. It suggests that Tapejara was a master of “precision flying,” able to hover, turn on a dime, and navigate complex environments that larger, clunkier pterosaurs would avoid. It was the hummingbird of the pterosaur world—if a hummingbird was the size of a person and had a giant sail on its head.
