Dry Bones: A Longmire Mystery: Johnson, Craig: 9780143108184

When Jen, the largest, most complete Tyrannosaurus rex skeleton ever found surfaces in Sherriff Walt Longmire’s jurisdiction, it appears to be a windfall for the High Plains Dinosaur Museum—until Danny Lone Elk, the Cheyenne rancher on whose property the remains were discovered, turns up dead, floating face down in a turtle pond.

With millions of dollars at stake, a number of groups step forward to claim her, including Danny’s family, the tribe, and the federal government.
