It sounds like something from a very popular dinosaur theme park film series, but the idea of a prehistoric shark still swimming the seas today is one that has popped up every now and then in recent history. As recently as 2013, a film – promoted as being a documentary – suggested an animal known as the megalodon could still be alive... Is it? Dan and Ciaran find out.

Today, we're going on one of the biggest treasure hunts in history. There's something very special about this treasure hunt though. It was created by Forrest Fenn – an art dealer and author in the US – and unlike the treasure hunts you might read of in books or see in movies, he was very much alive and giving out clues. No pirates here... Just a stash of goodies worth thousands of dollars. It's the last episode of Mysteries of Science but don't worry, we'll be back with a new season very soon.  Until then... Stay curious.
