Unlikely: assuming all of the authors of the various papers were on earth at the time, the spacetime intervals separating their discoveries were almost certainly timelike, in which case there is no ambiguity in their ordering. Unless they were within a few ms of each other (in the earth's reference frame).
But (taking the joke closer towards absurdity) when using vector timestamps independent actions by people not communicating with each other don't have a well-defined order.
