In 1880, a winged humanoid was discovered in the Madisonville area of Connecticut, USA. In 1910, an inexplicable 'bird' appeared in the waters off Normandy, France, diving and rising to catch fish. By 1927, a large bird with a thunderhead was found in Sausalito. Similar large avian creatures were also reported in Santa Barbara, California, and surrounding areas in 1948, with sightings of these prehistoric-shaped birds occurring across various parts of the United States that same year. In 1963, strange flying creatures were recorded in New York and parts of the UK and the US.

In 1932, American scientist Edwin Dutton discovered a peculiar animal in the tropical jungles of Cameroon, Africa. This creature had pointed, webbed wings and emitted a piercing shriek. Its mouth revealed a set of white teeth, almost as if it were grinning mischievously. Although this pterosaur had been extinct since prehistoric times, its modern reappearance has left many puzzled. This creature returns at dusk, heading back from where it came and hiding in the marshlands.

These phenomena suggest that certain remote areas of the Earth may still harbor animals and beings from our past, presenting enigmas that contemporary scientists find difficult to explain. Scientific expeditions in the Congo have also documented local residents' reports of gigantic monsters, even discovering traces and fur samples left behind. This indicates that despite our many advancements, nature and history remain full of unresolved mysteries.
