With a lively rhyming text and vibrant paper collage illustrations, author-artist Bob Barner shakes the dust off the dinosaur bones found in museums and reminds us that they once belonged to living, breathing creatures. Filled with fun dinosaur facts (a T. Rex skull can weigh up to 750 pounds!) and an informational "Dinometer," Dinosaur Bones is sure to make young dinosaur enthusiasts roar with delight.

"From celebrated genetic anthropologist Jennifer Raff comes the untold story-and fascinating mystery-of how humans migrated to the Americas"-- 20,000 years ago, people crossed a great land bridge from Siberia into Western Alaska and then dispersed southward into what is now called the Americas. Until we venture out to other worlds, this remains the last time our species has populated an entirely new place, and this event has been a subject of deep...

Perhaps nudged over the evolutionary cliff by a giant boloid striking the earth, the incredible and fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially the mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic...

"Developed by literacy experts for students in kindergarten through grade three, this book introduces fossils to young readers through leveled text and related photos"--

Step back in time and follow dinosaur tracks around the world. Whether made by a few dinosaurs or large groups, these tracks provide clues to the movement and behavior of these lovable ancient creatures. What dinosaurs made the tracks and what do scientists think they were doing when they made them? The author tells the story in rhythmic rhyme that may be sung to the tune of Over the River and Through the Woods.

"When the twelve-year-old daughter of a British carpenter pulled some strange-looking bones from the country's southern shoreline in 1811, few people dared to question that the Bible told the accurate history of the world. But Mary Anning had in fact discovered the 'first' ichthyosaur, and over the next seventy-five years--as the science of paleontology developed, as Charles Darwin posited radical new theories of evolutionary biology, and as scholars...

"Engaging images accompany information about triceratops. The combination of high-interest subject matter and light text is intended for students in grades 2 through 7"--

Stephen Jay Gould borrowed from Winston Churchill when he described the conodont animal as a riddle wrapped in a mystery inside an enigma. This animal confounded science for more than a century. Some thought it a slug, others a fish, a worm, a plant, even a primitive ancestor of ourselves. The list of possibilities grew and yet an answer to the riddle never seemed any nearer. Would the animal that left behind these miniscule fossils known as conodonts...

"The theory of evolution unites the past, present, and future of living things. It puts humanity's place in the universe into necessary perspective. Despite a history of controversy, the evidence for evolution continues to accumulate as a result of many separate strands of incredible scientific sleuthing. In The Story of Evolution in 25 Discoveries, Donald R. Prothero explores the most fascinating breakthroughs in piecing together the evidence for...

When a Tyrannosaurus rex suffers pain from meat trapped between its enormous teeth, a nearby colony of ants risks entering the great creature's maw to make their own repast from the remains of the dinosaur's most recent meal. From this humble beginning, over the course of millennia, a symbiotic civilization achieves amazing advances, reaching dizzying heights in countless endeavors scientific and social, facing dangers and exploiting opportunities...
