" Douglas Preston's Tyrannosaur Canyon is unfortunately compared to Michael Crichton's Jurassic Park, which does neither book good service. Preston's book has no living dinosaurs, except for the flashbacks to 65 million years in the past that follow the life of a female t-rex. Where Crichton's book was a clever way to get people to understand cloning research, Preston's is all about paleontological speculation, with strangely less hard biology. So Tyrannosaur Canyon is an ultimately simpler, pulpier book, with a little more sex appeal, a little more cliche soul-searching, and people running from other people rather than raptors. It's a typical thriller up until the end, when the plot peters out into a pseudo-scientific conspiracy theory that you couldn't possibly predict because the book didn't build to it or even really hint at it. This leaves the novel a strange and incomplete mix of speculative pulp science and spicy thriller conventions. "
