An antler on a red deer stag. Velvet covers a growing antler, providing blood flow that supplies oxygen and nutrients. Each antler grows from an attachment point on the skull called a pedicle. While an antler is growing, it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone. [6]
Velvet antler is the whole cartilaginous antler in a precalcified growth stage of the Cervidae family including the species of deer such as elk, moose, and caribou. Velvet antler is covered in a hairy, velvet-like "skin" known as velvet and its tines are rounded, because the antler has not calcified or finished developing.
Examining signs of modifications to bones can offer conservation scientists information about age, usage, creative techniques, and previous attempts at conservation.

Flaked stone reduction involves the use of a hard hammer percussor, such as a hammerstone, a soft hammer fabricator (made of wood, bone or antler), or a wood or antler punch to detach lithic flakes from the lithic core. As flakes are detached in sequence, the original mass of stone is reduced; hence the term for this process.

They have a joint at one end, often forming a T or Y shape, but always with a swelling of the antler at that end. There is a circular hole drilled through the antler just below the swelling or joint, and often a smaller second hole nearby on the shaft. Typical examples range from 6 to 8 inches (15 to 20 cm) in length. [4]
