There have been some extraordinary dinosaur discoveries in our state over the past few decades, but the fossils that put Montana on the prehistoric map were found near Choteau by paleontologist John Horner beginning in the late 1970s. About 12 miles west of Choteau in an area that includes the famous Egg Mountain site, Horner and friends unearthed colonies of dinosaur nests as well as a bed of bones from a heard of over 10,000 duck-billed dinosaurs thought to have been killed by a volcanic eruption 75 million years ago. These discoveries along with Horner's research have done as much to advance our understanding of dinosaur behavior as any other fossil site in the world. Here are some highlights from the Choteau area discoveries. For a more detailed account of the evidence discussed below, you'll have to read Horner's book, Digging Dinosaurs.
