This is a slice of the Esquel Meteorite which was found in Chubut, Argentina in 1951 by a rancher digging a cattle pond. A single mass weighing more than 700 kilograms was found.
It is a pallasite meteorite, and that is why it contains such strange shapes and patterns. Pallasites are translucent, olivine crystals embedded in an iron-nickel matrix.
Despite more than 50 years of searching, no more pieces of this rare pallasite have been recovered.
