From the photographs we can find that there are footprints of a small animal at every top of zigzag. The zigzag cracks were controlled admittedly by the animal slightly disturbing just when they were breaking. There is a phenomenon worth researching further (fig. 1 ). Distributing equality of zigzags, the horizontal crack (F1) is cracked along the footprints strictly. The vertical one (F2) was not cracked regularly and confined by F1. The crack was展开更多
