Iron, coarse octahedite (IAB, Og)
Found 1776, 3 tons

One of several multi-ton iron meteorites from Mexico (e.g., Chupaderos, 24 tons; Morito, 10 tons) 'discovered' in early colonial times and, in some cases, apparently very well known to and utilized by the local population for some indefinite period.

The main mass is in Mexico City.
