The huge weight, if it is indeed correct, makes Gancedo the second-biggest meteorite ever discovered. The largest, incidentally, is the 80,000-year-old, 73-ton mega meteorite Hoba, which was found in Namibia in 1920.

Much like Hoba, though, Gancedo is composed of 92.6 percent iron and 6.7 percent nickel. In fact, before Iron-Age smelting was developed, meteorites – albeit much smaller ones than Gancedo – were the main source of iron for our distant ancestors.
