This segment focuses in on the anti-theft brief case, a device which pours out smoke and fire bullets when tampered with. Most of the information has come from fossil finds, usually involving individual bones but sometimes entire skeletons. By comparing fossils bones to those of modern vertebrates, paleontologists have been able to classify dinosaurs into two distinct orders based primarily on the structures of their pelvis. The saurischian dinosaurs generally had massive, solid bones which allowed them to grow enormous. Fossil bones not only allow scientists to classify dinosaurs, but they give a tremendous amount of information about an individual species life style.
Bones have their limits though.
They can't tell you what color the animal's skin was or if it lived alone or in groups. Have the students discuss and list which animal characteristics would be most easily identified by fossil bones and which would be impossible to tell. Remind them that as technology improves, scientists are capable of extracting even a greater amount of information from fossils. One source would be a local butcher shop. Obtain a variety of clean chicken, turkey, beef and pork bones and have students compare both the internal structure and external shape.
