Supplementary data 

Full zircon U-Pb geochronometric results of all grains analyzed from the Devil's Graveyard Formation. Individual zircon 238U-206Pb ages with > 10% analytical uncertainty (2s) or >15% discordance between 238U-206Pb and 235U-207Pb age were excluded from TuffZirc weighted mean calculations. All analyses were conducted at the UTchron laboratory at the University of Texas at Austin.
