Fossils in and Out

Fossils In and Out covers the formation and preservation of fossils: traces of ancient life. We focus primarily on mold-and-cast fossils: fossils where the original structure is completely dissolved after burial, leaving a void of material where the object was called a Mold. Over time, groundwater can deposit mineral grains and fill in the fossil mold, creating a Cast of the organism. Museums copy this model to create lifelike replicas of fossils for display in museums, and so will we!
