The section of dermis that covers the dorsal wall of the pedal bone (distal phalanx) and provides the vascular support for the stratum lamellatum of the hoof wall. The dermis is covered in hundreds of lamellae, running in proximo-distal direction down the dorsal wall of the coffin bone. At the distal end of the lamellae, there are several papillae, known as terminal papillae, it is from these papillae that the white line is secreted.

The lamellar dermis is an important component of the suspensory apparatus of the hoof.
