Antler - Wikipedia, the free encyclopedia |
 | | Antlers are the large and complex horn-like appendages of deer, consisting of bony outgrowths from the head with no covering of keratin as is found in true horns. |
 | | While an antler is growing it is covered with highly vascular skin called velvet, which supplies oxygen and nutrients to the growing bone; once the antler has achieved its proper size, the velvet is lost and the antler's bone dies. |
 | | Due to its hardness, antler was an important material for tools from the Palaeolithic onwards (points, harpoons, needles etc). |
