Marvel Two-In-One #36

Trapped in the "past", on the other side of a Bermuda Triangle wormhole, Ben Grimm and four other 20th century natives are trying to avoid being eaten by confused Brontosauri. After a quick trip over a waterfall, the quintet finds their way back to Ben's plane, where they locate the wormhole by tracking the radiation from the missing bomb Ben had been looking for when he got sucked through the wormhole. On the other side, back in our own time, Mr. Fantastic is waiting to meet Ben at Cape Canaveral, but the Jaguar Priest follows them through the wormhole...
