Reports by cryptozoologists about sightings of living flying reptiles in the jungles of Africa ignore the fundamental laws of biomechanics. The idea of the survival of large Mesozoic archosaurs is broken down by the hard facts of the paleontological record.
Pterosaurs possessed a specific respiratory system and a lightweight skeleton for conquering the air space. Climate change and the disappearance of the food supply at the end of the Cretaceous period made their adaptations an evolutionary dead end.
Biomechanics of flight of large archosaurs
The wing of the pterosaur was formed from a skin membrane stretched between the trunk and the extremely elongated fourth finger of the forelimb. This membrane was permeated by muscle fibers and blood vessels, which made it as vulnerable as possible. Any rupture of the membrane deprived the animal of the ability to glide.
The Azhdarchids, which reached a wingspan of 10 meters, required huge launch pads and powerful thermal updrafts. The dense tropical jungle where the mythical kongamato supposedly hides is physically unsuitable for taking off and maneuvering creatures with such aerodynamics.
Specific anatomical features of the taxon:
- pneumatization of bones, reducing the total mass of the skeleton;
- the presence of a complex system of air bags;
- lack of powerful keel muscles for waving flight.
The modern atmosphere has different parameters of oxygen density and concentration compared to the Cretaceous period. Giant flying reptiles simply would not be able to provide their muscles with enough energy to maintain flight. The metabolism of archosaurs was designed for a different biosphere.
Paleontological record and dating
Fossilization preserves not only bone remains, but also soft tissue imprints in fine-grained sedimentary rocks. The global stratigraphic section clearly records the complete disappearance of pterosaur remains at the Cretaceous-Paleogene boundary. The Cretaceous-Paleogene extinction wiped out all species of flying reptiles without exception.
Radioisotope dating confirms that the youngest pterosaur bones are about 66 million years old. Over millions of years of excavations on all continents, not a single fragment of a jaw or phalanx dating back to the Cenozoic era has been found.
Factors that exclude the hidden survival of the population:
- the need for a huge area to maintain genetic diversity;
- absence of traces of nutrition and specific coprolites;
- total displacement of birds from ecological niches.
Large animals are unable to survive in isolation for millions of years without leaving material traces in the geological layers. The evolution of mammals and birds has long filled all available food chains of the upper levels of forests and coastal zones. Predatory pterosaurs would not have been able to withstand food competition with modern ornithological species.
Analysis of photographic materials and evidence
All photos of the alleged pterosaurs, without exception, were subjected to rigorous digital and optical analysis. Research has proved that the famous pictures from the time of the American Civil War are recognized as gross falsifications. The models were created from papier-mache, and the perspective was distorted to visually enlarge the objects.
Eyewitness accounts are often based on optical illusions or incorrect identification of large bats. The Indonesian flying fox with a wingspan of up to one and a half meters at dusk is easily mistaken by impressionable tourists for a prehistoric monster.
Human perception tends to complete familiar images with a lack of visual information. Popular culture, dinosaur movies, and the press form a persistent archetype of the flying lizard. The scientific method requires the presentation of a physical holotype rather than blurred video recordings, so theories about pterosaurs remain pseudoscientific folklore.
