Careful study of fossil bone or tooth anatomy yields much
exact information about placement and strength of muscles, tendons, ligaments, nerves,
and blood vessels. In rare cases, skin and hair impressions or actual skin or hair remains.
Body weight is more difficult to gauge because fat leaves no impression on the skeleton.
