WEB DESK: A mountain lion killed in the US state of Idaho had a set of fully formed teeth growing out of its forehead, wildlife officials say.
The lion was legally shot dead by a hunter on 30 December.
The Idaho Department of Fish and Game says the teeth could be the remnants of a conjoined twin which died in the womb, or possibly a kind of tumour.
The lion was hunted after it attacked a dog near the town of Weston, Idaho. The dog survived, but a hunter set off in pursuit and killed the big cat a few hours later.
Mountain lions, a native species of big cat, are relatively common in Idaho. They are elusive animals which seldom come into contact with humans.
This can put predatory mountain lions into conflict with people, livestock and pets, says the Idaho Department of Fish and Game.
