Marrying Paleontology with Photography
The 78 splendid photographs of fossils in Ancient Microworlds, by Giraud Foster and Norman Barker (Custom and Limited Editions, $65), include barks, corals, leaves, fishes, crustaceans, seashells, opalized wood, cephalopod shells, Arizona petrified woods and Colorado dinosaur bones. Shown are Eocene palm roots from Texas, preserved in opaline quartz; a late Jurassic ammonite, replaced by pyrite enough to show suture lines, from Germany; a cross-section of the trunk of a Permian tree fern, also from Germany; and a Jurassic conifer from Patagonia, with seeds that contain embryos.
"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.
