Prosecutors say Casey Anthony killed her toddler on June 16, 2008 so she could live the good life, free of the responsibility of parenthood.
Casey's attorney told jurors Caylee accidentally drowned in the Anthony family's backyard swimming pool and no one reported her death.
Friday marked the second day of testimony dominated by graphic descriptions about the condition of the child's remains. Thursday's court session adjourned early after Casey fell ill.
The 25-year-old defendant was back in court first thing Friday morning. She kept her head down and dabbed her eyes and nose with tissues during testimony by John Schultz, a forensic anthropologist and archeologist who helped recover most of Caylee's bones from the crime scene.
From what he found, Schulz concluded Caylee's body was mostly intact inside layers of bags when it was dumped in a wooded area. Over time, he testified, the body was pulled apart and dragged by animals to other spots nearby.
As Schulz testified about a bone 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.
Schulz said he found that plant roots had grown through the matted hair surrounding Caylee's skull and through her bones.
