Book Description
Sixty-five million years ago, a comet or asteroid larger than Mount Everest slammed into the Earth, inducing an explosion equivalent to the detonation of a hundred million hydrogen bombs. Vaporized detritus blasted through the atmosphere upon impact, falling back to Earth around the globe. Disastrous environmental consequences ensued: a giant tsunami, continent-scale wildfires, darkness, and cold, followed by sweltering greenhouse heat. When conditions returned to normal, half the plant and animal genera on Earth had perished. This horrific chain of events is now widely accepted as the solution to a great scientific mystery: what caused the extinction of the dinosaurs? Walter Alvarez, one of the Berkeley scientists who discovered evidence of the impact, tells the story behind the development of the initially controversial theory. It is a saga of high adventure in remote locations, of arduous data collection and intellectual struggle, of long periods of frustration ended by sudden breakthroughs, of friendships made and lost, and of the exhilaration of discovery that forever altered our understanding of Earth's geological history.

Book Description
This overview of dinosaur discoveries in Mexico synthesizes current information about the geography and environment of the region during the Mesozoic when it was the western margin of the ancient continent of Pangea. The book summarizes research on various groups, including turtles, lepidosauromorphs, plesiosaurs, crocodyliforms, pterosaurs, and last but not least, dinosaurs. In addition, chapters focus on trackways and other trace fossils and on K/P boundary (the Chicxulub crater, beneath the Gulf of Mexico, has been hypothesized as the site of the boloid impact that killed off the dinosaurs). Dinosaurs and Other Reptiles from the Mesozoic of Mexico is an up-to-date, informative volume on an area that has not been comprehensively described until now.

Book Description
Stories in both English and Spanish. Atlantis: the lost continent is actually us in the future. As we progress in the sciences and technologies we are building Atlantis and somewhere in the future, Atlantis was destroyed as time meets itself with the past and consequently we are finding Atlantis as an ancient civilization of the past, in the present which is actually the future of us as we are the last city in the future, just as the world came to an end. The other short stories will also stimulate the mind and hopefully it is their final version and they're put to rest, and the chicken will thank you, so will the rooster.

Book Description
Did dinosaurs live millions and billions of years ago before humans or together with humans? God made every living creature in six days, both animals and humans. Fossils of dinosaurs together with humans have been found. Drawings of dinosaurs on caves have been found as well. Can the behemoth animal spoken in the book of Job be a dinosaur? How do we know they were not vegetarians? The behemoth is so strong that even a raged river can't disturb it, even when the Jordan gushes into his mouth. Vivieron los dinosaurios millones y billones de años antes que los seres humanos o juntamente con ellos? Dios creo todo ser viviente en seis días, ambos, animales y humanos. Fósiles de dinosaurios juntamente con humanos fueron encontrados. Dibujos y talladas de dinosaurios en cuevas han sido vistos también. Puede ser que el animal behemot hablado por Dios en el libro de Job un dinosaurio? El behemot es tan fuerte que aún un feroz rio no puede molestarlo, aún cuando el Jordán entra en su boca.
