During the age of dinosaurs, not all the incredible creatures were land-dwelling. Some of the most fascinating and awe-inspiring creatures were the prehistoric swimming and flying reptiles. These ancient beings ruled the seas and skies, showcasing a diverse range of shapes, sizes, and adaptations.

In this article, we will explore the top 10 prehistoric swimming and flying reptiles, from the largest and most fearsome to the lesser-known but equally intriguing species.

Top 10 Prehistoric Swimming and Flying Reptiles

Quetzalcoatlus

– Scientific Name: Quetzalcoatlus
– Period: Late Cretaceous (Maastrichtian)
– Location: North America

Quetzalcoatlus is a genus of azhdarchid pterosaur, known for being one of the largest flying animals of all time. Its name is derived from the Aztec feathered serpent god, Quetzalcoatl. The two confirmed species of Quetzalcoatlus, along with other azhdarchids, were the largest known flying animals of their time, with giant wingspans and long, stiffened necks.

Unlike the serpent god it was named after, Quetzalcoatlus had no feathers. Its body, including its wings made of skin and fibers of keratin, was covered with hair, as in all pterosaurs. This prehistoric creature is believed to have been warm-blooded and active, similar to dinosaurs.

The exact lifestyle and feeding habits of Quetzalcoatlus are still a subject of debate among scientists. Some believe it was an opportunistic carnivore, feeding on both carrion and live prey, while others suggest it had a lifestyle similar to that of a stork, stalking small prey items like lizards and insects.

Quetzalcoatlus had a long, sharp beak, similar to modern storks, which is often used as evidence for its ground-hunting behavior. Its front and back limbs also support the hypothesis that it may have hunted small animals on the ground, similar to storks or hornbills.

Arambourgiania

– Scientific Name: Arambourgiania
– Period: Late Cretaceous (Maastrichtian stage)
– Location: Jordan, possibly the United States

Arambourgiania is an extinct genus of azhdarchid pterosaur, belonging to the same family as Quetzalcoatlus. It is one of the largest flying animals ever known, with an estimated wingspan of around 10 meters (30 feet) or more. This prehistoric creature lived during the Late Cretaceous period, alongside dinosaurs like Tyrannosaurus rex.

The name “Arambourgiania” was given to this pterosaur in 1989 by Russian paleontologist Lev Nesov, in honor of French paleontologist Camille Arambourg. However, the name “Titanopteryx” was informally used in the West, partially because the new name was assumed by many to be a nomen dubium.

Arambourgiania is known for its unusually long neck, earning it the description of a “flying animal with a giraffe-like neck”. Recent research has suggested that the single known bone of Arambourgiania is actually part of a neck vertebra, not a bone from the hand as previously thought.

Like other azhdarchid pterosaurs, Arambourgiania was likely a skilled hunter, capable of both hunting and scavenging for food. Its large size and unique features make it a fascinating and lesser-known member of the prehistoric flying reptile family.

Liopleurodon

– Scientific Name: Liopleurodon
– Period: Middle to Late Jurassic (Callovian to Kimmeridgian stages)
– Location: Europe

Liopleurodon, meaning “smooth-sided teeth,” was an extinct genus of large, carnivorous marine reptile belonging to the Thalassophonea, a clade of short-necked pliosaurid plesiosaurs. It lived during the Middle to Late Jurassic period, approximately 166 to 155 million years ago, and was the apex predator of the seas that covered Europe during that time.

The genus name Liopleurodon was coined by Henri Émile Sauvage in 1873. Sauvage named three species which he assigned to this genus, each based on a single tooth. One tooth, measuring 7.5 centimeters (3.0 inches) long, was found near Boulogne-sur-Mer, France, in layers dating from the Callovian, and was named Liopleurodon ferox. Another tooth, measuring 7 centimeters (2.8 inches) long with a crown length of 5.5 centimeters (2.2 inches), was named Liopleurodon grossouvrei.

Liopleurodon was a formidable predator, with a skull and jaws that took up one-fifth of its total length, giving it a powerful bite. It is often recognized for its appearance as the villain in the BBC’s “Walking with Dinosaurs” TV series. The exact size of Liopleurodon is still a topic of debate among scientists, with estimates ranging from 5 to 15 meters (16 to 49 feet) in length.

This prehistoric marine reptile remains a fascinating and iconic creature of the Jurassic seas, showcasing the diversity and power of the ancient world’s top predators.

Shastasaurus
