Dinosaurs: The Encyclopedia, Supplement 7: 8 - Tapa blanda

"an exciting and ambitious effort to bring updated information to interested readers in a timely way...richly illustrated...a highly descriptive and detailed academic work...an authoritative reference work...value...highly recommended"--Choice.

This reference work is the seventh supplement to Dinosaurs: The Encyclopedia (a 1998 American Library Association Outstanding Reference Book) and follows the intent and format of the encyclopedia and previous supplements. This supplement, as did its predecessors, offers primarily new information based upon the more recent research of vertebrate paleontologists; also, it corrects previously errors that may have crept into earlier volumes and emends outdated information. Among the many dramatic events discussed and updated are the first record of a dinosaur of any kind from Bulgaria, the first evidence of cannibalism in the genus Tyrannosaurus, the first evidence suggesting that some of the most avian dromaeosaurid theropods might have been venomous, the oldest known dinosaurian embryonic specimens recovered to date, and the first relatively complete dinosaur described from Korea. Supplemental volumes do not repeat information from earlier volumes, but build upon them.
