Nine years after the untimely demise of the bright Dr. Michael Crichton a good writer , more talented than many believed, his third posthumous novel Dragon Teeth, is published (he's been busier than numerous authors still technically alive) . If you're looking for an early version of Jurassic Park you will be disappointed, but this book has a feel to it that will keep you turning the page...Essentially the story of two ruthless pioneering paleontologists , historical figures, and great rivals in the 19th century, "The Bone Wars" , digging in the old , dangerous west , in canyons , hills , deserts, always lethal accidents or unfriendly incidents can occur, caused by humans both red and white, for dinosaur fossils , an ancient extinct animal, recently discovered. College professors Othniel Charles Marsh from Yale and his younger, former friend Edward Drinker Cope, from the small Quaker university in Philadelphia, Haverford, both are mad. Any underhanded trick to spoil and discredit the other is fine, they hate with a passion. Big eastern newspapers, (if you pardon the pun, had a field day with their plots) grown men , seeking glory in new finds... And loathsome childish pranks that kept readers amused. William Johnson 18, a lazy freshman at Yale, a rich man's son, quite full of himself, during the centennial celebrations of 1876, held in his hometown, Philadelphia, a short trip from the New Haven, Connecticut campus were he doesn't study...twice put in probation, wrecking private property he gets bored easily and father pays for damages...what's the big deal? Professor Marsh is taking students out west this summer, and Mr. William Johnson, not wanting to lose a bet from his nemesis a fellow arrogant student , an insufferable archenemy... so instead of a leisurely pleasant voyage to Europe and a sightseeing tramp around the continent... it becomes a dirty, awful, backbreaking dig for some old bones as the relentless sun and boss, burns your hide... the Sioux are on the warpath ( if I were you, I'd stay out of Montana), all this nuisance just to show how brave he is.... Famous people he encounters, (Wyatt Earp in particular , is quite charismatic) on trains and western boom towns , some less known, quickly after a brief acquaintance, enter boot hill , not very happy going...Many work for Marsh and Cope, the unscrupulous duo, not at the same time obviously, neither one tells the truth very often or fails to kick a man when he is down. An unexpected, enjoyable romp into history, for people who like to experience the atmosphere of a bygone era and walk in other men's and women's boots. They too can join their hazardous adventures for a short duration...Without any danger to themselves.
