Yeah, I'd like to hear more about how they attempted to date it. Most of the dating techniques I know aren't going to work well on a big chunk of metal, coz you can't make assumptions on multi-alloy isotopic ratios (maybe the uranium/lead ratio is weird coz they put uranium in there for some reason, not because it's young, or maybe they made ultra-low-uranium alloy rather than it being super old.) I'm vaguely suspicious from how the article is phrased that they're dating the organic materials found beside it.
I'd start by trying to determine what it's a piece of.
Knowing it's a 'port side manifold cover' (example) would eliminate it being of extraterrestrial origin.
I'd also be looking at the degradation. How long would it take for lime or other crystals to form and grow to that thickness, and would that help us arrive at a date for the underlying object?
Lastly, where was the object found? A disused airstrip? A junk yard? The site of that airliner crash in 1957?
Bob Lai: dug up from the bottom of a riverbank, 10 meters down. And while I agree that figuring out what it's from would be helpful, that presumes the what-it's-from is knowable. If it's part of an alien spacecraft, or some weird German WWII experiment in rocketry, it may not be identifiable by anyone living. Based on my experience playing with magnesium-zinc-copper casting alloys of aluminum, it might not take long buried in water to get some pretty awesome corrosion going on, like decades rather than millennia.

Of the two of them, we now know which one Vlad "the Mad" Putin believes is the girl in their relationship. For a "macho macho man" like #DonaldTrump that's going to hurt. #TrumpNation http://www.denverpost.com/2017/09/05/vladmir-putin-donald-trump/

If it were in sea water for only 2 days it would look worse.
