15706. THE CONTROVERSY OVER DINOSAUR METABOLISM. This paper provides an overview and analysis of the controversy over dinosaur metabolism and the ongoing debate concerning whether dinosaurs were endothermic or ectothermic. Following a brief introductory overview of the implications of endothermy versus ectothermy for species physiology and survival, the essay examines the main arguments and evidence directly related to dinosaur metabolism, the analysis also considers the implications of the recent findings on the KT event and the mass extinctions for dinosaur metabolism. Concludes that the metabolism of dinosaurs was probably heterogeneous (some were endotherms and others ectotherms). KEYWORDS: dinosaurs biology metabolism endotherm ectotherm term paper. APA Style. 13 pages, 34 footnotes, 18 bibliographic sources.
