Fossil #1: Saudi Arabia, 
Kuwait, Qatar, Oman

First place fossil goes to these four Parties for risking the good faith and integrity of the negotiations by blocking all attempts to secure a technical review of the 1.5 target and suggesting that vulnerable countries use Google to get information that they need/want. They did this in the teeth of emotional pleas from vulnerable countries and 
numerous rounds of diplomatic efforts to reach a compromise.

Saudi Arabia even gave us a list of traded goods which would be in peril from a 1.5 target. See if you can spot which one is their true concern: rice, cocoa, tomatoes, coal, oil.  (If you’re stuck, look up their chief export on Google.)
