Fantastic Four #346

In "70 Million Years BC...and Then Some!", the Fantastic Four face their most primal challenge yet—trapped on a prehistoric island with no powers and time itself slipping away. As they struggle to find a way back to their own era, the threat of extinction looms larger than ever. Written and illustrated by Walter Simonson, with cover art by Simonson, this 1990 issue delivers a high-stakes adventure where survival depends on wit, not strength.
