Pretty cool find, and found in the county I live in. 3 tiny towns in this county, Mitchell, Spray and Fossil.
That is pretty special, particularly considering it's supposedly the first dino fossil found in the state.
Maybe you can find and dig up the rest of it. :)
I like that part of the world. In high school, we used to go on OMSI field trips to Fossil, and one of my brothers spent a summer at Camp Hancock around 1967 or so. Then I worked for the Forest Service on the Ochoco National Forest for a few seasons in the 80s. There used to be a really good restaurant in Mitchell then, wonder if it’s still there. In 2017 my wife and I watched the eclipse near Seneca, and that’s the last time I’ve been to Oregon.
