Petrified Lightning - 2.545" Saharan Fulgurite rockinaboxstromatolite The classic Cavern Club brickAbove: Front of the Specimen Card.

These natural time capsules allow scientists to study the composition of ancient climates. This specimen is a 2. 545" fulgurite collected in the Sahara Desert. Originally
