Avisauridae leg formed by fused metatarsals (the bones which comprise the foot in humans). As a result, members of this family are distinguished from other enantiornitheans exclusively by features of the tarsometatarsal and pedal phalanges (toe bones). Unlike in some prehistoric birds, avisaurid tarsometatarsals were not completely fused, with the distal (outer) parts of the metatarsals being separate from each other. The proximal (near) half of metatarsal III (the long bone in the middle of the tarsometatarsus) is convex from the front. The inside edge of this bone's trochlea (toe joint) has a bony tab which points downward, known as a
Halving the Bones years prior to the events depicted in the documentary. In Japan, when someone is cremated, their bones are not reduced to ash.

Ruth is given a fragment of skull, a small part of a rib, and an unidentified bone to bring back the United States for her mother who did not attend the funeral. Reluctant to give the bones to her mother, Ruth lets the bones sit in a tea can on her shelf in her closet. Years pass by, and
