Barack Obama and Sir David Attenborough meet in Alice's Resturant...

No, this isn’t the setup for a joke. Two newly described Edicaran fossil species in Australia have been named Obamus coronatus and Attenborites janeae in honor of the above-mentioned historical live guys.
(Acceptable comments in the thread including discussion on the nature and/or coolness of these Edicaran fossils in specific and Edicaran fauna in general and attempts to construct the joke suggested in the subject line.)**
