Brachylophosaurus Humerus

BDM 121.012 This humerus belongs to a juvenile *Brachylophosaurus* from the Judith River Formation of Northern Montana (Campanian, ~77mya). This limb bone, along with many others from a duckbill dinosaur bonebed, show evidence of carcass scavenging behavior from carnivorous theropods like *Daspletosaurus*. Many gouging teeth marks are recorded along the bone surface as the predator worked to dismantle the carcass. From public lands administered by the Bureau of Land Management.
