1. What Exactly Are Pterodactyls and Pterosaurs?
Pterodactyl is a widely used term but not scientifically precise. It’s a general term for pterosaurs, reptiles from the order Pterosauria. Paleontologist David Hone at Queen Mary University of London estimates there are over 130 identified pterosaur genera. These creatures were widespread, living from China to Germany to the Americas. Pterosaurs existed from the late Triassic period to the end of the Cretaceous period (228 million to 66 million years ago), coexisting with dinosaurs but not belonging to the dinosaur family.
2. How Do Pterosaurs Differ from Dinosaurs and Birds?
Pterosaurs were flying reptiles, not dinosaurs. According to the journal Zitteliana, they lived alongside dinosaurs and became extinct around the same time. It’s crucial to remember modern birds didn’t evolve from pterosaurs. Instead, birds descended from small, feathered, terrestrial dinosaurs. This distinction highlights the unique evolutionary path of pterosaurs within the history of life on Earth.
3. When Was the First Pterosaur Discovered and Named?
In 1784, Italian scientist Cosimo Collini identified the first pterosaur, Pterodactylus. Initially, Collini thought he had found a marine creature that used its wings like paddles, as reported by the Geological Society of London. In 1801, French naturalist Georges Cuvier suggested these creatures could fly. Then, in 1809, after a fossil skeleton was discovered in Bavaria, Germany, he coined the term “Ptero-dactyle”. Although scientists later identified different genera of flying reptiles, “pterodactyl” has remained the popular term.
4. What Does “Pterodactyl” Mean and How Did Pterosaurs Fly?

The term “Pterodactylus” comes from the Greek word pterodaktulos, which means “winged finger.” According to the American Museum of Natural History, this describes their flight mechanism: a skin and muscle membrane stretched from an elongated fourth finger on each hand to their hind limbs. Pterosaurs also possessed membranes between their shoulders and wrists, possibly incorporating the first three fingers. Some even had a third membrane between their legs, sometimes connected to or incorporating a tail.
5. Were Pterosaurs Warm-Blooded or Cold-Blooded?
Early research suggested that pterosaurs were cold-blooded and better suited for gliding than active flight. However, later discoveries indicated some pterosaurs, such as Sordes pilosus and Jeholopterus ninchengensis, had furry coats of hairlike filaments called pycnofibers. As the Chinese Science Bulletin suggests, this indicates they were warm-blooded and generated their own body heat.
6. How Fast and Agile Were Pterosaurs in Flight?
A study published in the journal PLOS One suggests pterosaurs had powerful flight muscles, allowing them to walk on all fours (like vampire bats) and vault into the air. Once airborne, the largest pterosaurs (Quetzalcoatlus northropi) could reach speeds over 67 mph (108 kph) for short bursts and then glide at around 56 mph (90 kph).
7. What Was the Size Range of Pterosaurs?
Pterosaurs varied significantly in size. Nemicolopterus crypticus, the smallest pterosaur, discovered in China’s Liaoning Province, had a wingspan of only 10 inches (25 centimeters), according to the Proceedings of the National Academy of Sciences. In contrast, Pterodactylus antiquus had an estimated adult wingspan of about 3.5 feet (1.06 meters), according to the journal Paläontologische Zeitschrift.
8. Which Pterosaur Species Were the Largest?
The largest species soaring during the Jurassic period was Dearc sgiathanach, with remains found on Scotland’s Isle of Skye, revealing a wingspan exceeding 8 feet (2.5 meters), according to the journal Current Biology. Pteranodon, discovered in 1876, had a wingspan ranging from 9 to 20 feet (2.7 to 6 m), as noted in Current Research in Earth Sciences. Coloborhynchus capito had a wingspan of about 23 feet (7 m). However, Quetzalcoatlus northropi is believed to be one of the largest pterosaurs, with a wingspan reaching 36 feet (11 m), as reported in the journal PLOS One.
9. What Were the Distinctive Physical Characteristics of Pterosaurs?

Given the wide variety of pterosaur types, physical characteristics differed considerably. Many pterosaurs had long necks, sometimes with throat pouches for catching fish, similar to those of pelicans. According to the journal ZooKeys, most pterosaur skulls were long and filled with needle-like teeth, except for the Azhdarchidae family, which included Quetzalcoatlus northropi, known for being toothless. Crests on their heads were a distinguishing feature. These crests came in different forms, including bony, fleshy, or even saillike crests.
10. What Was the Purpose of the Crests on Pterosaur Heads?
Scientists have proposed various purposes for these crests, from heat regulation to serving as rudders during flight. However, as David Hone and his colleagues argued in a 2011 study in the journal Lethaia, the most likely function was for sexual selection. Juveniles lacked crests, indicating the structures were relevant only to adults for mating purposes.
11. What Did Pterosaurs Eat and How Did They Hunt?
Pterosaurs were carnivores, though some may have occasionally eaten fruits, according to David Hone. Terrestrial pterosaurs consumed carcasses, baby dinosaurs, lizards, eggs, insects, and other small animals. Water-loving pterosaurs ate marine life such as fish, squid, crab, and shellfish.
12. How Did Marine Pterosaurs Manage to Hunt and Avoid Drowning?
In 2014, Hone sought to learn more about the lives of marine pterosaurs, finding that juveniles dominated the fossil record. He hypothesized that juvenile pterosaurs often died by drowning rather than being eaten. Testing this, Hone and his colleague Donald Henderson modeled how well pterosaurs could float on water. They found pterosaurs floated well but had poor floating postures, with their heads close to or on the water.
This suggests that aquatic pterosaurs would launch into the air shortly after diving for food to avoid drowning. Young pterosaurs, with less developed muscles or still learning to fly, would have more difficulty launching from the water, potentially leading to drowning.
13. What Can Fossilized Teeth Tell Us About Pterosaur Diets?
According to Nature, researchers have discovered wear patterns on fossilized teeth of toothed pterosaur species, providing insights into their diets. For example, Dimorphodon, a roughly 3-foot-long pterosaur, was previously believed to be a fishing reptile. However, dental evidence revealed wear patterns that would have been produced by eating insects and land vertebrates rather than marine life.
