As well as their world class fossil displays, a new exhibition of astounding images and renowned retail collection, a mystery of epic proportions is unfolding these school holidays.

What happened?

Three hundred and sixty million years ago in a fishy town named Mudhole Springs (Canowindra) a puzzling mystery took place.

Our hero Ossi the Grossi (Canowindra grossi) is new in town and after a night out at "Jimmy's Oxygen Bar" his precious fin-ring gemstone has gone missing".

"We need junior detectives to follow the clues and find the secret of the Mystery in the Mudhole," explains Museum manager Warren Keedle.

"Follow the clues and find out who was responsible for this crime."

If you manage to solve the crime you will take home your own precious gemstone as a reward.

Each participating child from 5yrs to 15yrs old will be given a list of suspects with their museum entry and can cross them off as they are eliminated from the list by following the clues hidden around the museum.

If you're feeling the mystery solving is a little beyond yourself, the museum also has a new exhibition running, Fins to Flight.

This is an exhibition of astounding images from world renowned wildlife photographer Akos Lumnitzer.

These stunning images highlight the ecological and evolutionary progress from Fish to Birds.

The exhibition will be on public display from January 1 to February 2 in the foyer of the Age Of Fishes Museum Canowindra.

Entry to the exhibition is free of charge.
