I stopped at Lake McConaughy (near Ogalalla, Nebraska) on my way out to Colorado and picked this (along with some nice burrow casts, probably clam) from one of the beaches. I’m not very familiar with the fossils in this part of the state and wondered if anyone could help me with who this chunk of bone may have belonged to. I know it’s a stretch to id this considering how little of the bone is there and the lack of either end, but any help would be appreciated.
