Dr Leslie Griffiths, a medical forensic officer employed by Queensland Health, examined accused wife killer Gerard Baden-Clay on April 22, 2012 and again on June 14, 2012 and told the court he believed the two scratches on Baden-Clay's face were caused by finger nails.
"I'm saying that I believe it's caused by a finger nail and I have reasons to believe that," he said.
"A finger nail would be at right angles to the skin.
"That (the injuries) could be explained by a convex nail being drawn down the face ... producing an elongated wound."
Defence barrister Peter Davis said the two scratch marks weren't entirely parallel - one started higher and slightly curved away.
"You've got two quite significant scratches which would indicate quite significant force," he said.
Dr Griffiths said that could be explained.
"It could be simply explained by the fingers moving during that exercise," he said.
But Mr Davis said the doctor's explanations were "purely speculation".
"All you can say is it is consistent with finger nails provided you make various assumptions," he said.
The court was also shown lighter scratches on Baden-Clay's neck, on the opposite side to the marks on his jaw.
Dr Griffiths said he believed the marks on the neck were also caused by fingernails.
He said neither the scratches in the face or the neck would have bled.
Another photograph showed scratches and bruising on Baden-Clay's upper chest on the left hand side.
"I think that's a bruise," the doctor said.
"There appears to be a pattern to that bruise - I believe that's a superficial bruise."
The same photograph shows a separate small yellowish bruise on the right hand side of Baden-Clay's chest.
Dr Griffiths said the yellow colour showed the bruise was at least 18 hours old.
