Where is the dura mater in spinal cord?

The dura mater is the outermost layer of the meninges that surrounds and protects the spinal cord. It lies just inside the vertebral column and extends from the foramen magnum at the base of the skull down to the second sacral vertebra. The dura mater forms a protective sheath around the spinal cord and is separated from the vertebrae by the epidural space, which contains fat and blood vessels.
