This is definitely a tentative ID on my part considering that so little of the beetle is actually visible. :(

I am kicking myself for not getting better images, but when I stopped to photograph this very sticky patch of Columbian Black-tailed Deer scat, I wasn't even thinking that this was a beetle. I recall taking photos because I wanted a record of whatever weird thing (fruit pit? large seed?) I imagined the deer had consumed. It was only later when I was viewing the magnified version that I was fairly certain I could make out elytra and a pronotum.

Confirmation or correction of my suspicion as to species would be excellent. Thanks so much for any help!
