Brief answers to 100 questions children asked the editors of Owl magazine, but not everything dinosaur lovers would like to know. Questions vary from intriguing (""Why did huge dinosaurs lay such small eggs?"") to silly (""Were baby dinosaurs cute?""). Some responses don't really answer the question: ""How big was T-rex?"" ""T-rex was so long that it could bite the diving board in most backyard pools while banging on to the wall at the shallow end with its tail."" Format is fussy, with three columns of text, photos of fossils, and drawings that vary from authentic to annoyingly rubberized or cute. Some, reproduced from museum murals, are too reduced in size to be useful. Brief ""dinosaur quiz,"" with answers in the back; glossary; index. Adequate where demand is insatiable.
