So I am in the process of changing the oil pan gasket on my newly acquired 1990 FJ62 (pretty miserable job BTW) and this is what I found at the bottom of the oil pan when it finally decided to come off.

Truck ran just fine, and I don't see anything missing or out of the ordinary. It is the same size and thread pitch as the nuts found at the bottom of the connecting rod caps, but none of those are missing. There aren't too many other areas where this could have come from.

Any ideas? Should I be concerned?

Perhaps from one of the studs that hold down the rocker assembly?

There's no passage large enough for anything that large to pass from the top end to the bottom end. So I'd carefully examine the entire bottom end if there are no nuts missing from the Main Caps. Connecting Rods or possibly the oil pump mounts. I'd say your good.

That's what I am thinking. Definitely nothing missing. I did check the oil pump mounts too. Maybe a "leftover" from original assembly? Gasket looks original so I doubt anyone else has been in there yet.

You are correct, I just checked as I was sure they were large enough...

Correct. At least nothing visible or obvious from the bottom end. All rod caps have their respective 2 nuts each, and it's not from the oil pump or pick up.
