adding onto my other post- TW spoiled for skull!!
i added more photos, and i’ll try to explain better this time
so two of these skulls are coyote, a human and an unknown species (just searched up animal skull)
in the middle of the jaw there is a line, and usually the jaw is split in half from that spot. why is that and what is the purpose of the line? does it make it more weak in the spot?
