A captivating look at the life of a modern-day fossil hunter who makes the find of a lifetime. Wendy has…
an eye for the unusual and is skilled at finding things that others don't see. On a middle school field trip, she spots one of those unusual things --- it's fossilized coral 100 million years old! Wendy's thrilled! And soon, she gets hooked on hunting fossils. She decides to turn her passion into her career and becomes known as the “fossil whisperer” around the world. But it's close to home where she makes her most amazing find: Wendiceratops! Make no bones about it, a dinosaur species named after you is way cool! Kids will be wondering: what might be buried where I live?Par Richard Leakey, Richard E Leakey. 1994

origins. Leakey's position is that in spite of what certain evolutionary events suggest, it is social behavior, not mechanical devices like tools, that drives the evolutionary forcePar Marc Simont, Franklyn M. Branley, Franklyn Mansfield Branley. 1989

Rockies. Gould's account of the 1909 discovery of the Burgess fossils and their incorrect classification forms one part of this book; another deals with the evolution of the creatures that survived the fossils' era, and their place in the history of lifePar Caroline Arnold, Richard Hewett. 1989

to what life was like long ago. The author describes the work of paleontologists in learning about dinosaurs, especially the discoveries made at Dinosaur National Monument in Utah. For grades 4-7 and older readersPar Dan Flores. 2022
In 1908, near Folsom, New Mexico, a cowboy discovered the remains of a herd of extinct giant bison. By examining…
flint points embedded in the bones, archeologists later determined that a band of humans had killed and butchered the animals 12,450 years ago. This discovery vastly expanded America's known human history but also revealed the long-standing danger Homo sapiens presented to the continent's evolutionary richness. Distinguished scholar Dan Flores's ambitious history chronicles the epoch in which humans and animals have coexisted in the "wild new world" of North America-a place shaped both by its own grand evolutionary forces and by momentous arrivals from Asia, Africa, and Europe. With portraits of iconic creatures such as mammoths, horses, wolves, and bison, Flores describes the evolution and historical ecology of North America like never before. In thrilling narrative style, informed by genomic science, evolutionary biology, and environmental history, Flores celebrates the astonishing bestiary that arose on our continent and introduces the complex human cultures and individuals who hastened its eradication, studied America's animals, and moved heaven and earth to rescue them. Eons in scope and continental in scale, Wild New World is a sweeping yet intimate Big History of the animal-human story in AmericaPar Kathleen Weidner Zoehfeld, Julius Csotonyi. 2019

of the museum's collection is on exhibit on its 700,000 square feet of floor space; the rest is squirreled away in twenty-three interconnected buildings. Preston takes us on a grand tour of its library of bones, labs, vaults, corridors, and storage rooms, reporting on the museum's mind-boggling treasuresPar John Foster. 2022
This volume, aimed at the general audience, presents life and times of the amazing animals that inhabited Earth more than…
500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies. Grazing, predation, and multi-tiered ecosystems with animals living in, on, or above the sea floor became common. The cascade of interaction led to an ever-increasing diversification of animal body types. By the end of the period, the ancestors of sponges, corals, jellyfish, worms, mollusks, brachiopods, arthropods, echinoderms, and vertebrates were all in place. The evidence of this Cambrian "explosion" is preserved in rocks all over the world, including North America, where the seemingly strange animals of the period are preserved in exquisite detail in deposits such as the Burgess Shale in British Columbia. Cambrian Ocean World tells the story of what is, for us, the most important period in our planet's long historyPar Lisa Wheeler, Kurt Cyrus. 2006

hominidés ont-ils quitté l'Afrique ? Qui étaient donc les petits hommes de Flores ? De quand dater les premiers peuplements de Chine ? Quel est le véritable inventeur du feu ? À toutes ces grandes questions, Yves Coppens, dans ce livre qui lui ressemble, à la fois profond et plein d'humour, donne des réponses tout à fait nouvelles.Partant des origines de l'homme, il nous raconte aussi la romanisation de la Gaule, l'industrie du sel ou encore la culture viking et nous fait prendre ainsi conscience de l'actualité étonnante de ce passé dont nous sommes tous issus." -- 4e de couvPar Roger Cohen. 2008
