People across the Lower Eyre Peninsula were encouraged to bring in curious bones they had found for South Australia Museum scientists to examine as part of this year's SALT Festival.
Over the course of the two-hour bone detective workshop several families, children and adults brought in their findings for SA Museum mammal specialist Dr Cath Kemper and disease specialist Dr Ikuku Tomo to inspect.
Oscar and Zane Hamilton-Reid brought in a box full of bones they had collected and found at beaches in Fishery Bay and Sleaford.
Dr Kemper identified a seal skull the boys had found and a piece of whale bone, before taking photographs of two presumed bird skulls for further investigation back at the museum.
Museum scientists will re-examine the photographs taken of bones that were unable to be identified on the day and will email through their findings to the owners.
The pair both said the workshop was "really cool".
Dr Kemper said some bones had tested her as her specialty was mammals, but she would endeavour to find out what the bones were that she could not identify.
She said people had brought in seal skulls, kangaroo bones, various species of shark teeth, whale bones, different vertebrae and a range of other bones.
"It's wonderful to see that kids are still interested in natural history," she said.
"The Lower Eyre Peninsula has a lot of interesting sightings for live animals...other species come in here as the upwelling brings in all kinds of marine life."
Dr Kemper said she encouraged people to take photographs and provide details of sightings, including strandings or deaths of marine animals, as the museum provided the state's statistics to the federal government.
In addition to the workshop there was also a mini-display of seal, whale and dolphin specimens on loan from the SA Museum at the Port Lincoln Hotel.
The bone detectives was one of two events hosted by Natural Resources Eyre Peninsula across the 10-day event.
