Jack Horner Dinosaur Hunter Below Independent Readers Unit A Level 3

"When Jack Horner was a child, he was fascinated by dinosaur fossils. He hunted for them and dreamed of being a great paleontologist. But Jack struggled with school and reading. Jack found his own way to success and became one of the world's most famous paleontologist!"--

Have you ever wondered what left behind those prints and tracks on the seashore, or what made those marks or dug those holes in the dunes? Life Traces of the Georgia Coast is an up-close look at these traces of life and the animals and plants that made them. It tells about how the tracemakers lived and how they interacted with their environments. This is a book about ichnology (the study of such traces) and a wonderful way to learn about the behavior of organisms, living and long extinct. Life Traces presents an overview of the traces left by modern animals and plants in this biologically rich region; shows how life traces relate to the environments, natural history, and behaviors of their tracemakers; and applies that knowledge toward a better understanding of the fossilized traces that ancient life left in the geologic record. Augmented by illustrations of traces made by both ancient and modern organisms, the book shows how ancient trace fossils directly relate to modern traces and tracemakers, among them, insects, grasses, crabs, shorebirds, alligators, and sea turtles. The result is an aesthetically appealing and scientifically grounded book that will serve as source both for scientists and for anyone interested in the natural history of the Georgia coast.

"Bubbles over with the joy of scientific discovery as he shares his natural enthusiasm for the blend of sleuthing and imagination."—Publishers Weekly, starred review What if we woke up one morning all of the dinosaur bones in the world were gone? How would we know these iconic animals had a165-million year history on earth, and had adapted to all land-based environments from pole to pole? What clues would be left to discern not only their presence, but also to learn about their sex lives, raising of young, social lives, combat, and who ate who? What would it take for us to know how fast dinosaurs moved, whether they lived underground, climbed trees, or went for a swim?Welcome to the world of ichnology, the study of traces and trace fossils – such as tracks, trails, burrows, nests, toothmarks, and other vestiges of behavior – and how through these remarkable clues, we can explore and intuit the rich and complicated lives of dinosaurs. With a unique, detective-like approach, interpreting the forensic clues of these long-extinct animals that leave a much richer legacy than bones, Martin brings the wild world of the Mesozoic to life for the 21st century reader.

This book offers a thorough appraisal of Operation Allied Force, NATO's 78-day air war to compel the president of Yugoslavia, Slobodan Milosevic, to end his campaign of ethnic cleansing in Kosovo. The author sheds light both on the operation's strengths and on its most salient weaknesses. He outlines the key highlights of the air war and examines the various factors that interacted to induce Milosevic to capitulate when he did. He then explores air power's most critical accomplishments in Operation Allied Force as well as the problems that hindered the operation both in its planning and in its execution. Finally, he assesses Operation Allied Force from a political and strategic perspective, calling attention to those issues that are likely to have the greatest bearing on future military policymaking. The book concludes that the air war, although by no means the only factor responsible for the allies' victory, certainly set the stage for Milosevic's surrender by making it clear that he had little to gain by holding out. It concludes that in the end, Operation Allied Force's most noteworthy distinction may lie in the fact that the allies prevailed despite the myriad impediments they faced.

Drawn from a 2005 international symposium, these essays explore current tyrannosaurid current research and discoveries regarding Tyrannosaurus rex. The opening of an exhibit focused on “Jane,” a beautifully preserved tyrannosaur collected by the Burpee Museum of Natural History, was the occasion for an international symposium on tyrannosaur paleobiology. This volume, drawn from the symposium, includes studies of the tyrannosaurids Chingkankousaurus fragilis and “Sir William” and the generic status of Nanotyrannus; theropod teeth, pedal proportions, brain size, and craniocervical function; soft tissue reconstruction, including that of “Jane”; paleopathology and tyrannosaurid claws; dating the “Jane” site; and tyrannosaur feeding and hunting strategies. Tyrannosaurid Paleobiology highlights the far ranging and vital state of current tyrannosaurid dinosaur research and discovery. “Despite being discovered over 100 years ago, Tyrannosaurus rex and its kin still inspire researchers to ask fundamental questions about what the best known dinosaur was like as a living, breathing animal. Tyrannosaurid Paleobiology present a series of wide-ranging and innovative studies that cover diverse topics such as how tyrannosaurs attacked and dismembered prey, the shapes and sizes of feet and brains, and what sorts of injuries individuals sustained and lived with. There are also examinations of the diversity of tyrannosaurs, determinations of exactly when different kinds lived and died, and what goes into making a museum exhibit featuring tyrannosaurs. This volume clearly shows that there is much more to the study of dinosaurs than just digging up and cataloguing old bones.” —Donald M. Henderson, Royal Tyrrell Museum of Palaeontology
