内容简介

Paleontologist Robert T. Bakker tells the amazing story of a day in the life of a pack of Deinonychus dinosaurs. Readers follow the creatures as they single out, kill, and devour an injured tenontosaur; climb up into a tree; fall asleep; and are themselves stalked by a giant predator. Includes an explanation of how scientists study rocks and minerals; fossil roots, claws, teeth, and bones; and modern predators to understand raptor behavior.

作者简介

Robert T. Bakker (born March 24, 1945) is an American paleontologist who helped reshape modern theories about dinosaurs, particularly by adding support to the theory that some dinosaurs were endothermic (warm-blooded). Along with his mentor John Ostrom, Bakker was responsible for initiating the ongoing "dinosaur renaissance" in paleontological studies, beginning with Bakker's article "Dinosaur Renaissance" in Scientific American, April 1975. His special field is the ecological context and behavior of dinosaurs.

Bakker has been a major proponent of the theory that dinosaurs were "warm-blooded", smart, fast, and adaptable. He published his first paper on dinosaur endothermy in 1968. His seminal work, The Dinosaur Heresies, was published in 1986. He revealed the first evidence of parental care at nesting sites for Allosaurus. Bakker was among the advisors for the film Jurassic Park and for the 1992 PBS series, The Dinosaurs. He also observed evidence in support of Eldredge's and Gould's theory of punctuated equilibrium in dinosaur populations. Bakker currently serves as the Curator of Paleontology for the Houston Museum of Natural Science.

京东原版书的活动很给力！中文书也不错！价格优惠，送书速度快。唯一就是包装太差，送来的书常被压坏。。要是能用箱子就好了，箱子可以回收，一样环保。有一次送来的书，因为塑料袋破损还缺了一本，还好后来快递员在仓库找到了。好险哪！
