DATING DINOSAURS AND OTHER OLD THINGS by Karen Liptak

DATING DINOSAURS AND OTHER OLD THINGS

Age Range: 12 & up

KIRKUS REVIEW

 Humankind has kept records for only a few thousand of its two million years; scientists (archaeologists, paleontologists, anthropologists) and historians are still finding new ways to read our history and that of the eons that preceded us. The remains include rocks, fossils, and artifacts; there's a variety of dating methods and tools--rock layering, potassium/argon migration, radioactive carbon decay, tree rings--each with its own strengths and limitations. Those in current use, plus some that are still experimental, are described here with examples of their uses. The result is a wide-ranging overview of methods and tools. Objects, time frames, and some of the people involved are also depicted in drawings and photos. Liptak's prose is a little leaden, but serviceable, though her explanations can be skimpy: ``trillion'' is explained, but ``half-life'' is deferred to the glossary, and although potassium/argon dating is described as the major dating clock for dinosaurs, neither word appears in the index. Uneven, then, but since there's little on the subject, it'll make a useful addition to science collections. Glossary; further reading; index. (Nonfiction. 12+)
