David Hone, a palaeontologist at Queen Mary University of London, says there are at least 130 valid pterosaur genera. They lived in many locations across the globe, from China to Germany to the Americas.
According to the journal Zitteliana, the Pterosaurs first appeared in the late Triassic Period and were in the skies until the end of the Cretaceous Period. The Pterosaurs were not dinosaurs and became extinct at the same time. Pterosaurs were flying lizards.
The ancestors of modern birds were small, feathered dinosaurs.
According to the Geological Society of London, the first pterosaur discovered was identified in 1784 by Italian scientist Cosimo Collini, who thought he had discovered a marine creature that used its wings as paddles.
The term "Ptero-dactyle" was first used after the discovery of a fossil skeleton in Germany. Scientists realized they were finding different genera of flying reptiles when they used this term. pterodactyl was the popular term.
The Greek word pterodactylus means "winged finger" and is an apt description of its flying apparatus. According to Mcgill University, the wings of Pterodactylus and other pterosaurs were made up of a skin and muscle that stretched from the hands to the hind limbs.
Some groups of pterosaurs had a third membranes between their legs, which may have connected to or incorporated a tail, and the reptiles had a third membranes between their shoulders and wrists.
Pterosaurs were thought to be more suited to gliding than active flying. Scientists discovered that some pterosaurs, including Sordes pilosus and Jeholopterus ninchengensis, had furry coats that were warm-blooded and generated their own body heat.
According to a study published in the journal PLOS ONE, pterosaurs had powerful flight muscles, which they could use to walk as quadrupeds, like vampire bats. The study found that the largest pterosaurs could reach speeds of over 67 mph for a few minutes and then glide at a cruising speed of over 90 mph.
The smallest pterosaur was discovered in the western part of China. A description of the animal was published in the journal of the National Academy of Sciences. According to the Carnegie Museum of Natural History, half of the wing of this flying reptile was occupied by a long finger.
The only known species of pterosaur, Pterodactylus antiquus, had an adult wingspan of about 3.5 feet. The size of the Pterodactylus was confused early on because some of the specimen were juvenile rather than adults.
The Dearc sgiathanach was the largest species that existed during the period. The journal Current Biology states that the remains of a pterosaur were found in Scotland and had a wingspan of more than 8 feet.
Othniel C. Marsh discovered Pteranodon in 1876. The Kansas Geological Survey's Current Research in Earth Sciences bulletin states that it had a wingspan from 9 to 20 feet. It is thought that Pteranodon hunted fish over the open ocean. According to the American Museum of natural History, the pterosaurs would have rarely been seen on land and could have spent their time on the water. Their wings would have had to generate a lot of force to lift them from the water.
Coloborhynchus capito was a large pterosaur with a wingspan of about 23 feet. An examination of a fossil that had been in the Natural History Museum of London since 1884 led to the discovery.
According to the journal, the largest pterosaur is believed to be Quetzalcoatlus northropi.
The physical characteristics of the winged reptiles varied depending on the genera.
Pterosaurs had long neck and throat similar to pelicans for catching fish. The pterosaur skulls were full of teeth. According to the journal ZooKeys, the pterosaurs of the Azhdarchidae family were toothless.
Pterosaurs had a crest on their heads. It was thought that pterosaurs had no crests, but it is now known that they did.
Some pterosaurs had big, bony crests, while other crests had no bone. Hone told Live Science that some pterosaurs had a saillike crest made of a sheet of bones.
Scientists have proposed many possible uses for these crests, including that they were used for heat regulation or to serve as rudders during flight.
Hone and his colleagues argued in a study that the crests may have been used for sexual selection.
There are several lines of evidence that support this function of the crests, Hone explained, most notably that juvenile pterosaurs do not have crests, suggesting the structures are only used for something that is only relevant to adults.
Some Pterosaurs may have occasionally eaten fruits. Some species spent their lives around water, while others were more terrestrial.
Hone said that Terrestrial pterosaurs ate carcasses, baby dinosaurs, lizards, eggs, insects and various other animals. The water-loving pterosaurs ate a variety of marine life.
Hone wanted to learn more about the lives of marine pterosaurs. Hone said that juvenile animals dominate the fossil record. Young animals are usually those that are targeted by predators, preventing them from becoming part of the fossil record.
One hypothesis is that the juvenile pterosaurs died by being drowned. Hone and Donald Henderson modeled how well pterosaurs could float on water. Pterosaurs floated well, but they had poor floating postures, in which their heads rested very close to the water.
This suggests that aquatic pterosaurs wouldn't spend a lot of time on the water's surface and would launch into the air after diving for food. Hone said that young pterosaurs with weak muscles or still learning to fly would have a harder time launching back into the air from a dive.
According to Nature, researchers have discovered wear patterns on fossilised teeth that help to reveal their diet. Dimorphodon was thought to be a fishing reptile until dental evidence showed that it was more like a land animal.
