What kind of seeds are these?

In some bear scat. They are maybe 1/2” long. SW Colorado.

I tried using Google Lens. The AI suggested all sorts of things like beetles or pecans, which did not look like what you have in the image. Eventually I found a picture of Russian olive tree seeds, which looks like a pretty good match. When I Googled “Russian olive trees Colorado”, I found pictures of them growing in Jefferson County, Colorado, where they are considered an invasive species.

Yes, I think you are right. They grow out here, and bear (get it?) edible fruit.
