(4) 4-6 Illustrated by Mark Hallett. This oversize volume introduces the Smilodon fatalis, a saber-toothed cat that flourished in North America until roughly ten thousand years ago. The competently written text describes the Smilodon's physiology (which included seven-inch teeth), discusses their hunting techniques, and speculates on what caused their extinction. The accompanying color illustrations lack clarity and impact. Bib., glos., ind.

(4) K-3 Illustrated by Mark Hallett. Beginning with an account of a 1994 discovery of bear bones and wall paintings in a French cave, this oversize book introduces the cave bear, which flourished from 300,000 to 10,000 years ago. The intriguing text touches on the cave bear's physiology and way of life and speculates on how the animal interacted with humans. Some of the accompanying color illustrations have a muddy quality. Bib., glos., ind.

(4) 4-6 Illustrated by Mark Hallett. Beginning with a discussion of the Jarkov Mammoth, recently unearthed in a frozen state, the volume also describes mammoth physiology and way of life, traces its family tree, and speculates on the possibility of bringing these extinct creatures back to life through cloning. The capably written text is stronger than the serviceable color illustrations, but the book remains an intriguing introduction to mammoths. Bib., glos., ind.

(3) 4-6 Illustrated by Greg Ruhl. This story of the Apollo moon landing tells of both the historic space flight and the feelings of eleven-year-old Jan Aldrin as she watches events from Earth and waits for her father's return. Illustrated with color photographs and perhaps unnecessary original artwork, this cogent introduction is given added interest by supplying a child's perspective. A time line is included. Bib., glos.
