After a lifetime of walking with dinosaurs, I found my attention riveted by the paintings and sculptures from the collection of John J. Lanzendorf reproduced in Dinosaur Imagery: The Science of Lost Worlds and Jurassic Art (foreword by Philip J. Currie and photography by Michael Tropea; Academic Press, $49.95). These images demonstrate that restorations of dinosaurs are becoming more lifelike and that the animals were indeed otherworldly.
The works of art are arranged by geologic age depicted and portray dinosaurs as intermediate between reptiles, on the one hand, and birds and mammals on the other. Many are accompanied by commentary from a paleontologist, highlighting the tension between the analytic viewpoint of a scientist and the synthetic perspective of an artist. The art tempts one to generalize, stimulates reflection and focuses the reader on what, really, was a dinosaur. Do we have it? Is there anything missing—the distortion of a foot supporting a massive or accelerating body? the quasi-familiar details of ancient insects and plants? the smells, sounds and moods of the "former world" in which natural selection shaped the dinosaur?
What do the pieces tell us of ourselves? Tyrannosaurus rex is the most popular dinosaur. Two-thirds of the dinosaurs illustrated are raptors or large carnivores, and more than half of the herbivores are objects of impending or actual carnivory. Bird dinosaurs and dinosaurian herds are not as effective in capturing imaginations. Dinosaurian environments entirely vanish in sculpture. We have not yet exhausted the implications of the dinosaurian world.—Dale A. Russell, North Carolina State University and the North Carolina
"Penguins are 10 times older than humans and have been here for a very, very long time," said Daniel Ksepka, Ph.D., a North Carolina State University research assistant professor. Dr. Ksepka researches the evolution of penguins and how they came to inhabit the African continent.
Because penguins have been around for over 60 million years, their fossil record is extensive. Fossils that Dr. Ksepka and his colleagues have discovered provide clues about migration patterns and the diversity of penguin species.
