DINOSAUR DINNERS

What did dinosaurs eat? Most dinosaur fanciers know that some ate plants, others animals. This ``First Book'' provides photos of dinosaur and plant fossils as well as artists' renditions of various dinosaurs dining. The brief text is frequently sidetracked by irrelevant trivia: ``The plates on stegosaurus's back really gave it one of the first solar-powered heating systems!'' Or, ``Brachiosaurus didn't have a strong tail to help it stand, but if you weigh 70 tons...that might not help anyway.'' With so many outstanding books available on the subject, this seems unnecessary. Further reading; glossary; index.~(Nonfiction. 8-10)
