2:33pm: Court has resumed.
Forensic physician Professor David Wells is giving evidence by phone.
2:42pm: Professor Wells examined photographs of the injuries on Mr Baden-Clay's face.
He said the injuries were caused by a "blunt force".
"Look the first thing that does come to mind ... will be implements such as fingernails, or possibly a claw from a domestic animal ... and that would fulfil the type of injury and the arrangement of that injury," he said.
2:52pm: He said he could not see a "mechanism" where a blade could cause the injuries of the type seen on Mr Baden-Clay's face in normal use.
"It's an unusual site to get a shaving injury," he said, referencing the abrasions on Mr Baden-Clay's cheek.
"These are not being caused by a sharp object."
2:57pm: Professor Wells said the marks on Mr Baden-Clay's neck appeared to be linear bruises rather than scratches.
"It's a form of blunt trauma," he said, commenting on the cause of the injury.
Yet, he later added that fingernails could have caused the neck injury, "if the nails were applied across or over the top of fabric".
3:11pm: Under cross-examination from Mr Baden-Clay's defence barrister Michael Byrne QC, Professor Wells said an in person examination of injuries was preferred.
But he said that he would not hesitate making observations about a good quality photograph.
3:33pm: Professor Wells has been excused.
