CT (computed, computer, or computerized tomography) is a technology that enables highly detailed and nondestructive three-dimensional examination of solid objects using x-rays. It is perfectly suited for paleontology, as fossil material is often precious and irreplaceable, and information on internal structures is crucial for placing ancient species into their proper anatomical, and ultimately evolutionary, context. In the past, comparable data could be obtained only though serial grinding, in which a specimen was slowly ground away and illustrations made at small intervals, a process that is slow, laborious, and destructive.
