Yes.

I know because I once edited an article into Wikipedia. I needed a source for a generic claim (something reasonably well-known to experts in the field, such as "protons are made of UUD quarks"), and I just cited something I was familiar with. It wasn't even a good source for the claim - the paper didn't aim to prove the claim, it just contained one line that confirmed that the claim is very well known. But since I was familiar with the paper I didn't bother looking for something else.

A few months later, it turned out that the source, along with others in the Wikipedia article, had been cited by others for the same claim.
