Got stuck for two weeks trying to date a single pottery shard from a dig near Tucson

Found this plain looking piece in a test pit, thought it would be a quick ID. My professor said 'just run it through the lab,' but the carbon dating came back with a weird range that didn't match the site's other stuff. I ended up spending over 14 days cross checking soil layers and comparing it to pieces from three other sites before we pinned it down as a trade item from much farther south. Has anyone else had a simple find turn into a massive time sink like that?

Yeah that "massive time sink" feeling is real, but cross checking with other sites like you did is what finally worked for me too.

Massive time sink" is how you learn though, that's the job. My worst one was a bone fragment that looked modern but wasn't, and the process to figure that out is just what we do. Calling it a sink makes it sound like wasted time.

Yeah, @the_rowan you're right. That phrase makes it sound like you just wasted hours for nothing, but that's literally how we figure stuff out. I had a piece of ceramic once that looked exactly like a common modern type, but the context was all wrong. Spent three days going back and forth with the geologist before we realized it was a local clay nobody had documented properly. It was a slog, but that's the whole point of the job.

Read a paper on that exact thing, right?
