The Deep Time Diaries Paperback – October 1, 2000
From School Library Journal
Gr 4-6-Raham "transcribes" diaries kept by the two youngest members of a family of time travelers, then adds explanatory essays, places to visit, maps, sources for further information, and even games and puzzles. Ragging on one another in a brotherly/sisterly way, Jon and Neesha, with their parents, take an alien time machine to nine points in the distant past, beginning with a stop near the La Brea tar pits about 20,000 years ago, and ending in the Precambrian Era 800 million years earlier. Raham does not stint on specific detail in his supplementary material, which ranges from a plethora of mouth-filling scientific names, fossil-distribution charts, and which "dig-your own" fossil sites in the U.S. charge admission to an extensive glossary dubbed "Neesha's Selected Guide to Big Words." Though the illustrations-a mix of simple drawings and watery-looking color scenes-are nothing to write home about compared to the technically accomplished, melodramatic dinosaur art widely available in other books, and some of the various typefaces are thin to the point of invisibility, young proto-paleontologists will find plenty of solid information as they enjoy the Olifees' breezy observations and misadventures.-John Peters, New York Public Library

Author Gary Raham, a high school biology teacher, wrote science articles for publications like Highlights for Children before publishing Dinosaurs in the Garden (1988) then this book, Deep Time Diaries (2000). His website opens with the tag "where science, art and creative education coincide" and that is an apt description of Deep Time Diaries, which weaves fiction with solid scientific fact. In Deep Time Diaries, the Olifees, a fictional family from the early 22nd century, travels in a time machine to nine different points in time in Earth's past, progressively moving farther back into prehistory, encountering different prehistoric creatures and environmental conditions.
Chapters conclude with explanatory information and suggested fossil sites to explore including the La Brea tar pits in CA; Fossil Butte National Monument, WY; Dinosaur National Monument, UT; dinosaur tracks in Glenrose, TX; Dinosaur Ridge near Denver, CO; Petrified National Forest, AZ; and Yellowstone National Park, WY, to name a few. A full-color time scale placing the events in the story in their proper places within the Cenozoic, Mesozoic and Paleozoic geological eras is located at the back.
Here are the points in time to which the Olifees travel, and a preview of what they encounter:
Trip 1: Late Pleistocene, 20,000 years ago (they encounter saber-toothed Smilodons, man-eatingTeratorns, and tar pits)
Trip 2: Early Eocene, 51 million years ago (early primate Smilodectes, the fierce six-foot bird Diatryma, rhino-sized mammal Uintathere)
Trip 3: Late Cretaceous, 68 million years ago (Triceratops, Parasaurolophus, Ankylosaur, and monkey puzzle tree)
Trip 4: Middle Cretaceous, 110 million years ago( Cycads, Acrocanthosaurus, Deinonychus)
Trip 5: Jurassic, 145 million years ago (Brachiosaurus, Sauropod, Apatosaurus)
Trip 6: Triassic, 225 million years ago (Placerias, Coelocanth [still alive as a species today!], Icarosaurus, Coelophysis)
Trip 7: Carboniferous (late Pennsylvanian), 295 million years ago (Lycopods, Pelycosaurs, Seed Ferns, a huge tarantula)
Trip 8: Middle Cambrin, 525 million years ago (Trilobites, Sea lilies, Priapulid worms)
Trip 9: Precambrian, 800 million years ago (steaming pools with microscopic life)
If you have a budding paleontologist in your household -- or simply a child who loves prehistory -- you should check this book out.
