In 1961, an oil company geologist, Robert Liscomb, found dinosaur bones near Ocean Point along the Colville River. Unfortunately, he died soon thereafter and the bones ended up in a warehouse gathering dust for many years. The bone bed he discovered was later named for him. It was not until 1983 that the find came to the attention of dinosaur experts. About 95% of the bones from this bed have turned out to be Edmontosaurus, which was a large (15 meters long), non-crested duckbill. Largely juvenile bones (some adult) have been found here.
