Today we went exploring on the Cross A ranch 7,680 acres near the edge of the Powder River Basin. The rocks exposed near in the Powder River Basin are from the Cretaceous Period. First stop, there were some exposed dinosaur bones remaining from the previous dig by JP Cavigelli and his crew from the Tate Museum at Casper College in Wyoming. We dug a little less than a foot and found a toe bone from a hadrosaur, a small gar fish scale, and a small fossilized piece of a turtle shell. First time I have ever had the opportunity to dig for dinosaur bones and that was possible because of the UC Clermont Undergraduate Research Program. Going down the hill into the valley, you could see weathering and erosion caused by water. Digging through the sand stone we found iron concretions that had formed in the valley. Second stop, we found tendons and plant fossils exposed, as well as iron concretions and sandstone.
