The bones of a two-year-old girl, whose mother is accused of murdering her, showed signs of having been chewed by animals when they were found, a court has heard.
The gruesome evidence came in testimony from a professor of anthropology, who helped recover most of the bones, at the trial of Casey Anthony in Orlando.
Anthony has been charged with the first-degree murder of her toddler Caylee.
Prosecutors claim the 25-year-old used duct tape to suffocate the child.
But the defence argues Caylee accidentally drowned in her grandparents' swimming pool in the summer of 2008.
Caylee's remains were found in December that year in woodland near her home, almost six months after she was last seen by her grandparents.
Jurors have been shown photos of the youngster's decomposed skull.

Professor John Schultz told the jury how a team of forensics officers searched woodland, marking with tiny flags the locations where Casey's remains were found.
As he spoke about a bone which he said showed signs of having been "chewed on by an animal," Casey appeared to slump toward one of her lawyers, who wrapped an arm around her.
Forensics scientists testified earlier this week that high levels of chloroform were found in Anthony's car. Chloroform is a chemical associated with human decomposition.
The compound can also be used to render a person unconscious.
Prosecutors have said previously that an internet search on chloroform was conducted on a computer found in Anthony's home.

Under cross-examination, defence attorney Jose Baez pointed out that though there were two user-created accounts on Anthony's desktop, that did not mean someone else could have used the computer for the chloroform searches.
The trial has gripped the US and live coverage is being broadcast from the hearing.
Police had to break up a scuffle on Friday among members of the public waiting for a chance to get a seat in the courtroom to watch the murder trial unfold in person.
More than 100 people had queued for hours outside the Orange County Courthouse, some since 1am in the morning.
