The Boundary Trails Health Centre near Morden has a new patient, one that's been dead for 80 million years.
Researchers gave a mosasaur skull a CT scan.
The Canadian Fossil Discovery Centre says this could provide them with a lot of information on how the marine reptile acted when it was alive.
“Hopefully, we'll know the shape of the brain cavity, the size of it, and maybe even get a better picture of what the brain actually looks like," said Matt Duda from the Canadian Fossil Discovery Centre.
This is the first time a scan like this has been done in Canada.
The scan takes a few minutes and will determine different bone or rock mineral densities to gather information.
The CT technologist says they can blast the radiation far higher than they would for a human.
Preliminary results show a fracture on part of the skull and have provided some information.
No word yet when full results will come in.
