Looks like King Tut’s space dagger wasn’t so special after all.

Archaeologists study the archaeological record through field surveys and excavations and through the laboratory study of collected materials.Mining and smelting terrestrial iron was more difficult than creating bronze from copper and alloys like tin, and involved a reduction process that drew pure metal from unusable iron ore.The technology to do so didn’t appear until later, Jambon’s work suggests, and there weren’t any isolated incidents of iron smithing to muddy the waters.Earthly iron contains very little nickel, but it shows up prominently in iron from meteors.Analyzing the iron-cobalt ratio provides further evidence that the iron fell from the sky.
