In the late Cretaceous period, many animals began to take wing, and dinosaurs were no exception. Fly high with our dino-“soar” friends as well as Rain, Emily, and the rest of Dr. Da Vinci’s Dinosaur Explorers crew as they find out just how these flying creatures stay afloat! But these time travelers have to be careful--these aren’t friendly skies they’re flying in; the lord of the skies is an expert predator with a prehistoric eagle eye. It will take luck and ingenuity to survive this era and make it one step closer to making it home.

Trapped in the Precambrian Era 570 million years ago by an earthquake, the X-Venture Xplorers find themselves in a fix- by needing a bigger fix for their time machine! Rain, Sean and Stone are now faced with the challenge of finding electricity in an era where human haven"t even evolved! And to make matters worse, the locals don"t take kindly to them either! Witness all the wonders of our world"s past with these PREHISTORIC PIONEERS!

Plunged way back into the past, Rain, Emily, and the rest of the Dinosaur Explorers, continue to make their way back to the present, but first they must take the plunge and submerge themselves into the prehistoric oceans. What they find is that the weightlessness of the water caters to larger creatures, sometimes bigger than dinosaurs themselves! Here they must dodge carnivorous ancient dolphins, elude massive crocodile creatures, and essentially do their best to survive. But it’s also possible that they may even find some undersea friends. One thing is for certain, the Dinosaur Explorers are in way over their heads! Will they sink or swim?

Donald R. Prothero's science books combine leading research with first-person narratives of discovery, injecting warmth and familiarity into a profession that has much to offer nonspecialists. Bringing his trademark style and wit to an increasingly relevant subject of concern, Prothero links the climate changes that have occurred over the past 200 million years to their effects on plants and animals. In particular, he contrasts the extinctions that ended the Cretaceous period, which wiped out the dinosaurs, with those of the later Eocene and Oligocene epochs. Prothero begins with the "greenhouse of the dinosaurs," the global-warming episode that dominated the Age of Dinosaurs and the early Age of Mammals. He describes the remarkable creatures that once populated the earth and draws on his experiences collecting fossils in the Big Badlands of South Dakota to sketch their world. Prothero then discusses the growth of the first Antarctic glaciers, which marked the Eocene-Oligocene transition, and shares his own anecdotes of excavations and controversies among colleagues that have shaped our understanding of the contemporary and prehistoric world. The volume concludes with observations about Nisqually Glacier and other locations that show how global warming is happening much quicker than previously predicted, irrevocably changing the balance of the earth's thermostat. Engaging scientists and general readers alike, Greenhouse of the Dinosaurs connects events across thousands of millennia to make clear the human threat to natural climate change.

STEM-inspired comics adventures drawn in a full-color manga-style reminiscent of Dragonball Z, with special illustrated pages devoted to science facts. The Dinosaur Explorers—Rain, Emily, Sean, and Stone, along with Dr. Da Vinci, his assistant, Diana, and their robot helper, Starz-- were all flung back in time by Dr. Da Vinci’s particle transmitter, and the solar-power device can only bring them back to the present a few centuries at a time, giving them all a perfect opportunity to explore the past—provided they can actually survive it. They now find themselves back in the Jurassic, and they quickly find it’s no walk in the park (Get it?) (Sorry.). This is the grand age of dinosaurs, but also the time when the first non-dinosaur animals begin to stretch their wings!

While exploring the Triassic era, the X-Venture Xplorers are split in two- not by rampaging creatures or primal danger, but by simple squabbling! Stone and Emily continue on foot, while Rain and Sean take the vehicle for a spin! However, the era’s residents see this as an opportunity to score some bite-sized snacks! And things are only going to get worse! Read on and see how the X-Venture Xplorers escape being TRAPPED IN THE TRIASSIC!
