While this happened at the end of last December, it's still very worth sharing.
Nicolas Cage accidentally bought a black market Mongolian Tyrannosaurus in a bid. And had it returned to the Mongolian government once he learned out it ended up in the bid in the first place.
This isn't all that surprising, since a lot of dinosaur fossils come out of Mongolia that way; it's how Deinocherus' full body evaded us for so long.
I think the funniest part about it is that he outbid Leonardo DiCaprio for it.
