I live in the middle east and found these in an abandoned house in this field next to my house about two years ago . they all seem to be from the same animal as i found them all in the same little pile, unfortunately no skull only a jaw bone with some teeth (some of them a few feet away and had to dig around a bit to find them all) they are very small, I’ve placed an Australian 2$ coin and a measuring tape for reference.

i would also like to know how i can clean them as they are very dusty and grey but some of them are very dry and brittle and i am afraid to damage them .

(yes my sheets will be changed after this lol)
