Fourteen more or less archosaurian variations, 1950-94, compiled by the veteran anthologizer. Familiar to dinosaur buffs and science fiction readers alike will be such famous old tales as Ray Bradbury's ""The Fog Horn"" (sea monster falls in love with a lighthouse); Isaac Asimov's ""Day of the Hunters"" (warm-blooded, intelligent dinosaurs--written, astoundingly, in 1950!); Arthur C. Clarke's ""Time's Arrow"" (fossil hounds chased by a carnosaur); and L. Sprague de Camp's Mesozoic safari, ""A Gun for Dinosaur."" Almost as well known, if less venerable, are Edward Bryant's ""Strata"" (Mesozoic ghosts); Howard Waldrop's Indians and dinosaurs vs. soldiers and settlers in the ""Green Brother""; Robert Silverberg's dinosaur renaissance, ""Our Lady of the Sauropods,"" and--towering above everything else here--Poul Anderson's chilling time travel/nuclear war yarn, ""Wildcat."" Of the more recent entries, Sharon N. Farber's splendid commentary on ""bone warriors"" O.C. Marsh and Edward D. Cope will amuse paleontological cognoscenti; the others--from Patricia Cadigan, Kristine Kathryn Rusch, Robert J. Sawyer, and Harry Turtledove--look somewhat pallid by comparison. Still, Anderson's tremendous yarn by itself is probably worth the price of admission, while the other oldies cast a nostalgic glow.
