What's particularly mad is that this implies an ESTABLISHED ecosystem about 200My BEFORE the end of the Late Heavy Bombardment, previously accepted as the time of first life, and before the end of the Hadean. eon. The Theia impact (which formed the Moon and probably liquefied any crust the Earth had prior to it) happened around 4.4 to 4.45Gy ago, only 200My earlier.
(Implicit evidence for panspermia, anyone?)
