Perfectly preserved T-Rex tooth discovered buried in farmer's field could fetch £20,000 | Mail Online: "An 67 million year old T-Rex tooth unearthed sticking out of a farmer's field could fetch up to £19,000 at auction.

It is officially one of the oldest teeth ever discovered after a rancher stumbled across the ancient dentistry poking out of the soil after he ploughed his field in rural Garfield County, Montana, USA.

It is in such good condition, its tiny serrated edges, which helped the dinosaur grind down their preys bones, are still visible on the surface. "
