Trees probably a little optimistic (1.3 – 1.4 billion years before Carboniferous)
Not just uranium depletion though… Cowan, G. A. (1976) Sci. Amer. 235 36 Could it have happened elsewhere – probably yes… Could it happen today – probably not, 235U not 3% nowadays…

1.8 billion years later, under a squash court in Chicago… Fermi, 2nd Dec 1942 Chicago Pile 1 uranium sheets, graphite blocks, cadmium rods Coolant, shielding? -None
Became CP-2 when moved to Argonne. CP-3 Heavy Water “CP-4” -> EBR 1…
“CP-4” -> EBR 1… Partial core meltdown…
