Carbon Date

There's no way his wallet could have been where it was found—in the abelisaurid’s fossilized ribcage. The archaeologists carbon-dated the wallet leather to the same period as the dinosaur, so it was no prank. He’d lost it on a plane a couple months back, which explained exactly nothing. True, his dreams had always taken him to distant star systems and civilizations that never existed. And yes, he woke up most mornings with inexplicable new scars, but who doesn’t?  Plus the fact that the driver’s license—featuring his degraded yet still identifiable name and face—was from a year that hadn’t happened yet.
