Agatized dinosaur bones (aka gembones) are a rare type of fossil. To become agatized, first the original bone must be covered quickly in a material like ocean sediment or volcanic ash to prevent scavenging and keep oxygen out. In most cases, the bone is then permineralized - mineral rich ground water slowly seeps in and deposits some of those minerals in open cavities and tiny spaces in the cells. This is where the journey for most fossils ends. But when conditions are right, a second re-mineralization occurs and types of silica (jasper, agate, chalcedony, and my favorite kind of fossil - opal!) replace the first minerals, resulting in beautiful, shiny gembone!
