Argentavis is being highlighted for its extraordinary size, with reports describing the extinct bird as looking like a small biplane when it was in the air. Its wingspan is put at about 7 metres, making it one of the most striking examples of a giant prehistoric flyer.
The scale of Argentavis was not limited to its wings. The bird is also described as weighing around 72kg, an unusually high mass for an animal capable of flight. That combination of immense span and heavy build is what makes Argentavis such a standout subject in discussions about ancient bird life.
The comparison to a biplane helps capture just how unusual Argentavis would have appeared overhead. With such broad wings and substantial weight, it would have looked very different from modern birds familiar to most people today.
Details like its 7m wingspan and 72kg body continue to underline why Argentavis remains one of the most remarkable prehistoric birds ever identified. Even from the limited measurements alone, it is clear that this was an animal built on a scale rarely seen among flying creatures.
