After organizing the bones into groups (skull, ribs, vertebrae, leg bones) and labeling them, students will have to reference the bone diagram to help them identify the bones and assembling them on construction paper as shown in their bone sorting chart. �
There are charts showing bone illustrations with the skull and jaw of an shrew, brown rat, specific birds, vole, and house mouse. You may also find an owl pellet bone chart which has animal bone parts for example skull, jaw, scapula, forelimb, hind limb, pelvic bone, rib, and vertebrae.
