Download Flying Dinosaurs: How Fearsome Reptiles Became Birds by John Pickrell PDF

By John Pickrell

Unearthing the hot paleontologial discoveries, this interesting well known technology booklet exhibits that birds are direct descendants of dinosaurs. the invention of the 1st feathered dinosaur in China in 1996 despatched shockwaves during the paleontologial international. have been the feathers a part of a posh mating ritual, or a stepping stone within the evolution of flight? And simply how heavily comparable is T. rex to a fowl? Award-winning journalist John Pickrell unearths how dinosaurs constructed flight and have become the birds in our backyards. He delves into the most recent paleontological findings in China, the USA, and Europe and uncovers a thriving black industry in fossils and infighting among dinosaur hunters. He additionally investigates the arguable plan to exploit a chook to deliver dinosaurs again from the lifeless. maybe dinosaurs didn't die out while an asteroid hit Earth sixty six million years in the past. This booklet trips into the deep, darkish depths of the Jurassic to determine what occurred.

Download Long-Term Forest Dynamics of the Temperate Zone: A Case by Paul A. Delcourt PDF

By Paul A. Delcourt

The synthesis offered during this quantity is a right away outgrowth of our ten-year FORMAP venture (Forest Mapping throughout japanese North the United States from 20,000 year B.P. to the Present). Many prior study efforts in paleoecology have used plant-fossil facts as proxy details for basically geologic or climatic reconstructions or as a bio­ stratigraphic foundation for correlation of neighborhood occasions. by contrast, during this e-book, we care for ecological questions that require a holistic viewpoint that integrates the interactions of biota with their dynamically altering environments through the years scales as much as tens of hundreds of thousands of years. within the FORMAP venture, our significant study target has been to exploit late-Quaternary plant-ecological information units to guage long term styles and techniques in wooded area de­ velopment. with a view to accomplish this goal, we have now ready subcontinent-scale calibrations that quantitatively relate the creation and dispersal of arboreal pollen to dominance within the plants for the main tree sorts of japanese North the USA. Quantification of pollen-vegetation relationships presents a foundation for constructing quan­ titative plant-ecological facts units that permit additional ecological research of either person taxa and woodland groups via time. software of those calibrations to fossil­ pollen files for analyzing wooded area historical past therefore represents a basic step past conventional summaries dependent upon pollen percentages.

Download The Terrestrial Eocene-Oligocene Transition in North America by Donald R. Prothero, Robert J. Emry PDF

By Donald R. Prothero, Robert J. Emry

The transition from the Eocene to the Oligocene epoch, happening nearly forty seven to 30 million years in the past, was once the main dramatic episode of climatic and biotic switch because the death of the dinosaurs. The light tropical climates of the Paleocene and early Eocene have been changed by way of glossy weather conditions and extremes, together with glacial ice in Antarctica. the 1st a part of this publication summarizes the newest details within the relationship and correlation of the strata of past due center Eocene via early Oligocene age in North the United States. the second one half reports just about all the real terrestrial reptiles and mammals discovered close to the Eocene-Oligocene boundary, within the White River Chronofauna--from the turtles, snakes and lizards to the typical rodents, carnivores, oreodonts and deer of the Badlands. this is often the 1st finished therapy of those subject matters in over sixty years, and should be important to vertebrate paleontologists, geologists, mammalogists and evolutionary biologists.

Download Predator-Prey Interactions in the Fossil Record (Topics in by Patricia H. Kelley, Michal Kowalewski, Thor A. Hansen PDF

By Patricia H. Kelley, Michal Kowalewski, Thor A. Hansen

From the Foreword: "Predator-prey interactions are one of the most vital of all organism-organism interactions....It will in basic terms be by means of compiling and comparing facts on predator-prey relatives as they're recorded within the fossil checklist that we will wish to tease aside their position within the tangled net of evolutionary interplay over the years. This quantity, compiled via a gaggle of specialist experts at the proof of predator-prey interactions within the fossil checklist, is a pioneering attempt to collate the data now gathering during this vital box. it will likely be a typical reference on which destiny examine of 1 of the principal dynamics of ecology as obvious within the fossil checklist could be built."

Download The Link: Uncovering Our Earliest Ancestor by Josh Young, Colin Tudge PDF

By Josh Young, Colin Tudge

For greater than a century, scientists have raced to solve the human genealogy and feature grappled with its issues. Now, with an dazzling new discovery, every little thing we notion we knew approximately primate origins may well switch. mendacity within a high-security vault, deep in the center of 1 of the world's best traditional background museums, is the medical locate of a life-time - a wonderfully fossilized early primate, older than the formerly most famed primate fossil, Lucy, via forty-four million years.

A mystery formerly, the fossil - "Ida" to the researchers who've painstakingly established her provenance - is the main whole primate fossil ever chanced on. Forty-seven million years previous, Ida rewrites what we've assumed in regards to the earliest primate origins. Her completeness is remarkable - lots of what we comprehend approximately evolution comes from partial fossils or even unmarried bones, yet Ida's fossilization bargains even more than that, from a haunting "skin shadow" to her abdominal contents. And, remarkably, wisdom of her discovery and life nearly by no means observed the sunshine of day.

With unique entry to the 1st scientists to research her, the award-winning technological know-how author Colin Tudge tells the historical past of Ida and her position on this planet. a powerful, state-of-the-art clinical detective tale her discovery, and The Link offers a wide-ranging research into Ida and our earliest origins. even as, it opens a stunningly evocative window into our prior and alterations what we all know approximately primate evolution and, eventually, our personal.

By Michael J. Everhart

Revised, up to date, and accelerated with the newest interpretations and fossil discoveries, the second one variation of Oceans of Kansas provides new twists to the interesting tale of the big inland sea that engulfed relevant North the US throughout the Age of Dinosaurs. monstrous sharks, marine reptiles known as mosasaurs, pteranodons, and birds with enamel all flourished in and round those shallow waters. Their plentiful and well-preserved continues to be have been resources of significant pleasure within the medical group whilst first found within the 1860s and proceed to yield intriguing discoveries a hundred and fifty years later. Michael J. Everhart vividly captures the heritage of those startling unearths over the a long time and re-creates in unforgettable aspect those animals from our far-off prior and the area during which they lived―above, inside of, and at the shorelines of America’s old inland sea.
