The saber-toothed cat is one ancient animal that lived at the same time as early humans.  Fossilized bone tells us how the cats may have looked, how and what they hunted, and how they may have become extinct.  As large, strong animals, they may have preferred hiding and waiting for prey to walk by instead of chasing it.  They may have lived in groups (prides) who cared for injured cats, as fossils have revealed healed bones.  With no more than four sentences per double-page spread, the text is simple and clear.  Acrylic paintings provide colorful, detailed illustrations to support the information about this prehistoric, formidable predator.
