Toluca Iron Meteorites

The Toluca meteorite is a coarse octahedrite (Iron, IAB-sLL) meteorite, one of the oldest known meteorites on Earth. It fell in south-central Mexico as early as 50 to 60,000 years ago near the present-day city of Toluca. It was likely used by local peoples to craft tools and weapons, and was recognized as a meteorite by the West in 1776. Its main mass is held in Mexico City. When acid etched, this meteorite displays wonderful, interlocking Widmanstätten lines.
