Goat bite marks on chewcard.
This arc of marks on just one side of the chew card have been made by the incisor teeth on the goat's lower jaw. Goats have no incisor teeth on the upper jaw, onlu a bony pad, so there will be either no impression on the other side of the card or just a shallow rather vague dent. (Note: sheep, cattle and deer can leave very similar marks, varying mainly in size.)
