And what were the dominant terrestrial species at said time? Would there even be any? I have zero idea of what’s the expected survival rate of an iPhone in the fossil record, but I like to imagine a giant sloth stepped on one once and we are none the wiser.

Alternative title:

“Assuming the timeline is stable and time travel is possible, but no evidence is ever found until its invention, what would be the earliest acceptable time period for time-travel tourism, and the latest cut-off point no one would be allowed to go to?”

      A phone in a region with rock or ice flow might be grinded down into fine sand within hundreds of years. A smartphone touching lava will be burned to crisp within minutes

      A Nokia 3310 on the other hand would survive all of these without a scratch. 🙃
