Great choice!

Hmm, guns are fun so I'd like to bring some, you know for that feeling of security, but yep I reckon we should invent a force field of some sort just to mitigate the risk of any danger.

Pangea is a monstrously huge supercontinent so we might need some navigational equipment...I'll bring my Garmin GPS. No satellites back there though, so we might need to invent them.
