|Weasel and stoat skulls can only be reliably separated on size, but the largest male weasels can be larger than the smallest female stoats ! Nevertheless, they are "good species" and their skull lengths rarely overlap in Britain. Any skull less than 42mm overall length is almost certainly a weasel.|
