head
A head is the part of an organism which usually includes the ears, brain, forehead, cheeks, chin, eyes, nose, and mouth, each of which aid in various sensory functions such as sight, hearing, smell, and taste. Some very simple animals may not have a head, but many bilaterally symmetric forms do, regardless of size.
Heads develop in animals by an evolutionary trend known as cephalization. In bilaterally symmetrical animals, nervous tissue concentrate at the anterior region, forming structures responsible for information processing. Through biological evolution, sense organs and feeding structures also concentrate into the anterior region; these collectively form the head.

Head stamp on Smith 500 ammo
I was hoping someone might recognize this headstamp? The round is a 500 smith and Wesson. A gun I bought had 100 rounds of this ammo, being cautious on a big bore, I do not want to shoot it unless I know what it is. Thanks for any help in advance.- Discussion Thread
