The Baruri Carapace
This item was trawled from the bottom of the Baruri River (a tributary of the Rio Negro, which is itself a tributary of the Amazon) in Brazil, embedded in a lump of curiously hardened clay. The Baruri Carapace is a remarkably complete set of plate (breastplate, helmet) and scale mail (arms, legs); while the (presumably leather) bindings and linings used have long since rotted away, the armor plates and scales remained essentially intact. The Carapace was made for somebody about 5 feet 4 inches tall, although researchers are less sure about that.
