5 Year Old's Show-and-Tale (Isle of Wight)

The elementary school of a 5 year old in the Isle of Wight now has something interesting in the display case.

The youngster found a Beaker barb-and-tang which he thought was a dinosaur tooth.  The ailerons and tang are in perfect condition.

I saw this register in the Portable Antiques database several days ago and didn't think much of it.
However, the back story of how it was found makes it interesting.  From the BBC [Link]
